My Computer Monitor Does Not Show Anything When It Boots Up ?

June 18th, 2009

If you have little or no computer troubleshooting experience, then this article is for you. With windows. there is always a possibility of, nothing showing up on your computers monitor when you turn it on. You can find the root cause of the possible problem, if you debug in a systematic order.

When you switch on your PC the BIOS performs a series of diagnostic tests known as the Power On Self Test (POST). This involves checking the systems hardware components and their configuration.

To start with, when your system bootup process starts, you’ll see the BIOS message which will have the name of the graphics card and its memory capacity. This is an indication that your graphics card is being initialized and is working well enough. If bootup stops at this point then the problem is most likely to we with the graphics card.

Next comes the BIOS startup display, where you’ll see details of your BIOS chip and also what key to hit in order to enter the BIOS setup program. When you hit Enter, the system performs the memory test. If the memory test doesn’t start, then there might be a problem with your systems memory. If there is, then you’ll get appropriate error messages and you proceed according to the that.

Next comes detection of IDE devices such as hard drives and CD-ROM/DVD drives. If you get an error message which says system is having trouble identifying one or more of the IDE devices, then mostly the problem is with these devices or its configuration.

The BIOS will now attempt to identify any Plug and Play devices in the system. A hang up here is usually caused by an expansion card such as a modem or sound card. The card could be faulty or causing a resource conflict. Try unplugging all the cards in turn and restarting each time.

Plug & Play is a uniform standard adopted by all the major computer manufacturers. It allows a device to be installed to a system as painlessly as possible.

By now the system has identified all the hardware in the system. You should now see a system configuration summary detailing all the hardware it has found.

The BIOS will now attempt to find and load the operating system. First it will look in the floppy drive and then the hard drive. This will be indicated by lights and physical activity in the respective drives. Any failure at this stage indicates problems with the floppy or hard disk drives or their contents. If the operating system loads or begins to load then the hardware part of the boot process has been successful.

Pay careful attention to any beeps you might hear on starting up you PC. This is the BIOS telling you something is amiss. Remember that a single beep on startup is normal and indicates that everything is OK.

    @jake

    attach the vga cable to the graphic port by tightening the screw to the graphic port.
    it may be you turn the vga cable upside down during when you are attaching it to your computer

    @Gautam
    it may be one of the pin on your vga cable has removed.
    you may mistakenly turn the vga cable upside down
