The Dreaded Blue Screen – The Sight That Is Unbearable For Computer Users

Introduction:

Most of the computer users would have definitely come across blue screen problem, from where the system becomes unusable without reinstalling the operating system, or by changing the required hardware. Once the blue screen appears, your system will keep rebooting and you will not be able to use it. This problem is a very critical issue, and many users often complain and discuss about it on online forums.

Some of the issues experienced by users related to blue screen are:

In one of the tech forums, an individual posted a comment saying that her laptop was showing blue screen for the last few months while turning it on, and she has no clue about what was happening. It often hung showing a NMI parity check. Even after changing the motherboard, formatting the HDD and updating the BIOS, she is still unable to fix the issue.

  • Another regular computer user pointed out that his laptop keeps rebooting after displaying a blue screen after and there is nothing he can do to stop it. Thus, he keeps his system switched off most of the time.
  • One of the users was also facing similar issue with his Dell laptop. Whenever he tried switching his laptop, he was being prompted with a message stating if he wanted his laptop start normally or in the safe mode. On selecting either of the options the laptop was showed a blue screen with a error message “STOP: 0X000000F4 (0X00000003,0X84BA04D0,0X84BA061C,0X81290330)”. He was not sure about what to do like most of the other users facing similar issue.
  • Some computer users have tried reformatting their hard drive to resolve the blue screen issue. While it may have worked for a few, but it just does not seem to work for others. Obviously it looks like the problem does not just lie with the corrupt OS alone.
  • Some of the people have blue screen issue while working on a particular applications or program. Out of nowhere, their systems showed an error message that the system memory is full, and the computer screen turned blue. Many gamers also faced similar issue while playing. When they removed and placed the laptop battery back, the problem seemed to have resolved on its own, but it did create a doubt about the efficiency of their laptops in their minds.

Effective Solutions:

Many users have tried fixing this problem, while some of them did succeed, others were not so lucky. Those who were able to fix it stated that the problem occurred due to the following reasons, as mentioned below:

  1. RAM is not fitted accurately
  2. Less space in the OS drive
  3. Virus has affected the system

You can try troubleshooting the above mentioned issues, but if you are still unsuccessful, you might want to look for more answers in this link. Hopefully, your computer should be up and running smoothly in a matter of few minutes.

Tackle Windows 7 Freezing With Ease

What To Do When Windows 7 Freezes Booting?

A lot is anticipated from Windows 7 by many of us. Several people may point out that Microsoft has learnt some lessons from Windows XP and Window Vista launches. We are still facing the old set of issues that we came across in the earlier windows operating system. One major issue we came across from our users is that Window 7 freezes while booting.

This issue is normally because of the USB connection problem, therefore what you need to do is to detach every one of the USB cable connections and reboot the system. As soon as the computer completes reboot process, integrate a USB connection and then leave this for some time to find out if this link creates a problem.

You might also wish to reboot your system to find out if this relationship brings about freezing while rebooting your computer. Subsequently, carry on this procedure by connecting as well as removing every USB device individually until you can recognize the location where the hardware disappointment is arriving through. The problem is generally the effect of a wireless computer keyboard or even computer mouse or dongle. However, it can be the other device as well.

In the event you have observed that the issue is originating from wireless keyboard and mouse then you will have to examine your computer to find out that the “USB keyboard and mouse support” is enabled in BIOS setting. If this option is enabled then disable it to solve this issue.

Upgrade Computer BIOS

Upgrading Computer BIOS

The complete name of BIOS is “Basic Input-Output System”, which is a computer program that is found in the ROM memory within the motherboard. The major task of BIOS is to supply the information, which is necessary for the hardware compatibility with the computer. It consists the programming, which help the computer to boot. The BIOS does not have the capability of physical functioning, although, you are able to “Flash” BIOS if you feel it’s necessary.

Flashing the BIOS of PC could be dangerous, in case you are not cautious. There are chances of BIOS corruption if while updating power outage happens even for couple of seconds. In such circumstances, the only solution is to change your BIOS chip or even motherboard. When you prepare for upgrading BIOS, it is recommended to have UPS with the backup of at least 10 minutes as a preventive measure.

  • One of the common purposes of upgrading BIOS is to make Windows XP compatible with recent adware for resolving a system obstacle. Undoubtedly, BIOS upgrading could boost up the system performance and might allow you to utilize few computer hardware. However, it does not ensure solution for all system problems.
  • Next question that arises is how to find the appropriate update for your BIOS. If you are aware of the manufacturer of your desktop or Laptop such as DELL, HP, LENOVO then you can find the BIOS update from their website. For the self-assembled computers you will have to go to the website of motherboard manufacturer.
  • Next step pertains to the model no. of the motherboard or computer, for this you should note down the model no. of the motherboard or your computer to find out the appropriate update. You can find the motherboard model number from the memory test. You will have to put this model number in search box for update.
  • After downloading the upgrade, copy it on bootable CD or floppy. Now read the READ ME file instructions to install updates. Before proceeding further, take the back up of your OLD BIOS on CD.
  • BIOS manufacturers have numerous instructions for installing the update. The most popular is boot with the floppy or CD drive. Insert CD restart you PC and follow the instructions, after installation remove the disk.

Upgradation of BIOS is a very effective way to make your Windows compatible with the new amendments, and for resolving the hardware problems. We recommend you to upgrade your BIOS frequently with the proper care.

Use SecurAble To Check Whether Processor Possesses VT Support For Windows 7 XP Mode

Use SecurAble To Check Whether Processor Possesses VT Support For Windows 7 XP Mode

Specific Windows 7 editions come with optional components called XPM (Windows XP Mode, formally known as VXP (Virtual Windows XP)) and Windows Virtual PC, a virtual PC for Win 7 OS that allows you to run a virtual system for virtualization. You can run and access applications that are installed in virtualized XP instance on your Windows 7 desktop to enable backward compatibility.

XPM is simply a virtual system which runs Windows XP (pre-activated) that uses Windows Virtual PC features. XPM and Virtual PC possess improved functionalities which is why several Windows 7 users wish to have these optional components on their system.

The requirements of Virtual PC on Windows 7 are different as compared to Virtual PC 2007 (Service Pack 1). The main difference is that Windows Virtual PC needs hardware-assisted VT (virtualization technology) support. Microsoft has come up with KB977206 which helps users to hack Windows XP Mode and Windows Virtual PC so that they can be run without any hardware virtualization.

VT is a built-in technology in CPU processors. It is known as Intel VT in Intel chip while it is called AMD-V in AMD processors. This virtualization technology capability is incorporated into a tiny chip which cannot be removed or added manually. Even if your CPU possesses VT, you need to enable the same in BIOS.

A majority of recent CPUs posses default VT operation. However, some of the older CPUs running on OEM PC may not include VT. Without VT support, installation of Virtual PC might not be possible or it might not start working. You will be shown the below mentioned error message in such cases.

“Cannot Start Windows Virtual PC host process. Check the System event log for more details.

 Windows Virtual PC requires hardware-assisted virtualization. There is no hardware-assisted   virtualization support in the system.”

 

 

To check whether your processor supports VT, you would normally go through the list of Intel processor features or features list of AMD CPU. However, this might be pretty time consuming. Instead of doing so, you may confirm whether or not your processor supports VT by making use of SecurAble

SecurAble is a useful utility that displays the status of maximum bit length of your CPU, its DEP as well as virtualization support. You need to simply download SecurAble and directly run it. It does not require any installation. It will quickly display the status of hardware-assisted VT feature of your CPU. If it shows the status as “Locked On” or “Yes”, it means that you are free to use Windows Virtual PC.

In case it shows “No”, it means the CPU does not support VT feature. However, if you see the status as “Locked Off”, it means that VT support is not enabled in BIOS. In such a situation, all you need to do is, restart the system, go to BIOS configuration and turn on or enable the hardware virtualization support.

 

In case the hardware virtualization support is locked off or disabled in BIOS, you will see the below mentioned error when you try to run Windows Virtual PC component on your Windows 7 system.

“Virtual machine could not be started because hardware-assisted virtualization is disabled. Please enable hardware virtualization in the BIOS settings and try again.”

 

 

Apart from SecurAble, Microsoft’s HAV Tool is another utility that helps you detect the status of hardware-assisted virtualization support in your CPU.

Access The Windows BIOS Setup With Ease

Access The Windows BIOS Setup With Ease

A creation of Windows, the virtual machine is simulated and runs within the Windows itself, but it doesn’t mean that it doesn’t have the features or powers of the actual computer having a physical existence. The Basic Input Output System (BIOS) is a similar type of a low level component and has its existence in the virtual machine also.

Features or settings of normal BIOS like the system time, IDE configuration, system lock, power management, ACPI, user password and boot device sequence can be changed and viewed via the Visual Machine’s BIOS too. It gives the same privileges as its physical counterpart.

The Windows Virtual Personal Computer (WV PC) comes equipped with the AMIBIOS. Its predecessor the VPC BIOS was modified and changed by hackers to perform the OEM activations crack. In the Windows VPC, the authority or permission to access the setup utility of BIOS has been skipped because of the latest integrated and enhanced features which provide resource and device sharing between the guest OS and host.

 

It also brings on additional features like automatic logon to the guest Windows Operating System and the automatic publishing of the installed applications. Therefore, if we have to access the Windows VP’s BIOS configuration, then we have to disable and switch off some features like Integration Features for some time.

On the boot up process, the virtual machine performs the power-on-self-test (POST) with a black background. Press the Del key at this juncture and you will be allowed to access the setup utility of the virtual machines BIOS.

 

The above mentioned POST sequence finishes pretty quickly, so it is advised that the Del Key should be pressed in time in order to access the settings utility. After you finish accessing the system, just enable the integration features again and help the features get started again.

The Technology Behind Restarting Computers

The Technology Behind Restarting Computers

 

Shutting down and restarting computers is the most common application of any computer. Understanding the process of shutting down computers is pretty simple. Each one of us are habituated with this process in our home theatre systems, television sets etc. The process of restarting a computer is one which needs some thinking.

How does it manage to shut down all its running applications before getting shut down, then disconnecting the motherboard and the most curious part is that how does it manage to restart all its applications again all by itself.

It might be sounding like a maze, but the answer is not that confusing. Whenever we click the Restart command or press the restart button, the O.S shuts down all running and active programs. This is done in order to make its RAM free.

 

After regaining all the resources of the RAM, the OS issues a message command to its CPU in order to make the BIOS to take over and control over the booting process. BIOS load the first five hundred and twelve bytes of the detected device and then jumps to the boot loader before restarting the machine.

It is a misconception that shut down is a safer process, but the above explanation shows that the process of restarting is much simpler and safer.

My Computer Beeps When I Switch It On … What’s The Problem ?

This post is part of the series Boot-up Troubleshooter.

If somethings wrong with your motherboard and/or graphics card, then your PC will make some unusual noises in the form of beeps, these beeps are known as beep codes. These beep codes are actually produced by the BIOS chip.

The BIOS chip has an inbuilt diagnostic system whereby it alerts you to any problems it encounters during bootup. It does this in two ways – a series of coded beeps if the problem occurs before the graphics sstem has initialized or a text error message if the fault comes after.

Depending on your BIOS manufacturer, the beep codes will vary, so you’ll need to know who your manufacturer is before you analyze whats wrong with your motherboard and/pr grpahics card.

Finding who your manufacturer is very easy. As soon as you re-boot your system, you’ll notice your BIOS manufacturers detains at the top of the screen. You should quickly make a not of it as it won’t be displayed for long.

If you are a Windows ME user, you can get your BIOS details by:

::> Start -> Programs -> Accessories -> System Tools

::> Click System Information and look under System Summary.

There you’ll find information about your BIOS Version.

Simple Solutions To Common Problems That Might Be Troubling Your PC

I’ve pointed out some of the most common computer related problems new-bies face when they buy a new computer.

Sometimes your computer is working fine, and all of a sudden it starts behaving erratic. Is such situations, one of the first things to consider is what were you doing on the PC immediately prior to the fault manifesting itself. If you can identify something specific, that you were doing just before your PC/lap started acting funny, then most often simply ‘undoing’ it will eliminate the problem.

Let us, in this article look at most of the ‘common’ actions that may be the reason for your PC / laptop to behave the way it should not :

> Downloading from the Internet:

There are hundreds of thousands of known viruses, the vast majority of which are spread via the internet and their effects can mimic literally any computer fault. So if your PC starts giving trouble after downloading from the Internet there is a very good possibility that it has picked up a virus. If you suspect this to be the case then you must obtain an up-to-date virus program and check your system with it.

If you use internet often, download from unverified or untrusted sources, download attachments from unknown senders, then you should be aware that you are inviting trouble. You should never discount the possibility that your system can be infected by viruses, malwares, spyware and such that can be installed on your system through such programs.

You should also be very careful when you install any freeware programs. It is a very sketchy area, as a normal PC / Laptop user, you’ll have not have any idea if the freeware you want to install is infected or not. When you are downloading it from untrusted sources, it’s a safer way to visit related forums, discuss with people and see if the software you are planning to use is the best without any problems, or ask for suggestions. These days, with the internet boom, there are forums and communities that pretty much discuss everything you can think and imagine about !

> Installing a peripheral, i.e. a new scanner / Upgrading your PC with a new card, i.e. a graphics card:

Installing new hardware is a common cause of problems and is usually due to the new hardware device taking the resources allocated to an existing hardware device. This problem can usually be sorted out via Control Panel, System, Device Manager.

> Deleting/installing a program:

Often we install a program to try out and then having decided we don’t want it delete it. With most programs there is no problem. However there are some which simply refuse to go quietly. The usual problem is that these programs use or ‘borrow’ files and then when they are deleted, take these files with them. Any other programs on the PC which need these files will then not run correctly, if at all. The cure for this is to re-install the affected program.

There are occasions when simply running a particular program will cause problems. It will either have become corrupted or is incompatible with something else on the system. The result will usually be lockups and crashes. Deleting and then re-installing it will usually cure that fault.

> Changing your PC’s settings:

Windows is a very customizable operating system and allows the user to make all manner of changes to its default settings. This also applies to much of the systems hardware. However there are parts of the system where changes can have adverse effects on the PC’s performance. Examples are the BIOS and the registry. The best policy when experimenting with settings, is to make a written note of any changes made. If there are any subsequent problems then you’ll be able to reverse them.

If you are one those with inquisitive nature, to test and experiment new things and enjoy doing it, you should be a little more careful when you deal with your PC / Laptop with such an attitude. I don’t say its wrong if you try out something on your own, but I’d recommend that you better read up about the part you want to fiddle around with. It saves an arm and time. Always pen down whatever changes you’ve made to your system, which will come handy in case you fail to set it right if things go wrong.

> Shutting down / Restarting your PC the wrong way:

There is most definitely a right and a wrong way to shut down or restart your computer. The right way is to select Start -> Restart or Start -> Shutdown. You can also do a soft reboot by hitting Ctrl + Alt + Delete. The wrong way is to hit the reset button or power off button. This can corrupt any program that might be running, or worse, the hard drive itself. Usually though, the effects are minor and can be repaired by exiting in the proper manner and then running a disk utility such as ScanDisk.

Though often looked down on, I’ve seen a lot of problems caused by not exiting windows correctly. You should try and avoid your reboot button as much as possible. It must be used only when you have no option, like when your PC / Laptop is frozen solid. It should not be used as a time saver, quick option to shut down your system !

> Maintenance:

If, for any reason you have been delving inside the system case, its quite possible that you have inadvertently loosened or even disconnected something, a cable or expansion card for example. Try and retrace your steps, checking everything in the area in which you were working, making sure all boards and cables are firmly seated in their sockets.
