    Try the following steps and I gurantee you that the problem will be solved.

    1) open you computers cabinet,

    2) remove all the power cords from the devices it has been attached to, (i.e, hard disk, cd\dvd drive , floppy drive etc)

    3) remove the ram Module from its socket carefully.

    4) carefully blow of all the dust from the motherboard using a bower or u can use you vaccum cleaner with blower on mode.

    5) power on your system on the same state, and the switch it of again within 5 secounds

    6) again re-insert the ram module in its slot.

    7) power on your system again, this time you will be able to see the display on your computer, once you see the display switch off your computer again and plug in the power codes to all the devices from which you had unplugged.

    Chetan Karia's suggestions DO work - often does the trick for me, though officially "frowned upon"!

    Can I just emphasis,though, that you MUST make sure the mains power is off when you delve inside your machine for your own safety, and also discharge yourself of static by grabbing hold of a mains water pipe or something else that's earthed before you handle your RAM chips.

    Good luck!
