Pc boots, But no Display to the Monitor.

Specs: Windows XP
Almost 3 days before,

when i was playing a game my PC freezed then i planned on restarting it. After that there is no display on the monitor, the light on the monitor keeps blinking even when PC boots up.
So i decided to remove the graphics card and plug the monitor to integrated graphic chipset and the computer started.I bought this graphic card a week ago (XFX Geforce 8800GT).
Since the integrated chip is working i think motherboard and ram are fine.

The graphics card temp never got above 70C, So there was no overheating issue.

Is this the problem with graphics card or any other device.

Can a restart damage the graphic card?

I have tried things like resetting the bios, rubbing the graphic card with pencil eraser, checking the video cables etc and nothing seems to be working.

Any help would be appreciated!

Do you have a decent quality power supply with enough amperage to support the 8800GT?

Interesting graph at artstechnica. Shows power consumption under load @ 220w and peak @ 245w yet the specs on Nvidia website ( http://www.nvidia.com/object/produc... ) seem to say peak power consumption is 105w.

So in actual performance testing the power requirement is more than double the maker's spec. @245W that equates to a draw of over 20Amps on the 12V connection.
I suspect your powersupply has two +12V rails rated 18Amps on each. Those are meant to be peak load rather than continuous. Your graphics card has overloaded the PSU and the damage is now done. Whether the damage is to the card, powersupply or motherboard PCI-e slot remains to be determined.
