White Screen of Death

Guys need your help on this.

My Config is as follows:

Asus P5Q Delux
Quad Core 9550
Palit Sonic Edition Ati 4850.
G-Skill 1066 2GB DDR2.

I am able to boot the machine and go to the bios but within a minute the screen turn's white. I am suspecting the GFX Card but i am not sure. I dont know what the problem could be. Please help.

Thanks in Advance.

^ psu ? (10 chars)
did u try clearing the bios - enter the bios - restore to factory settings - and then save and exit ? (can be managed in a minute)

Bios reset done. No Use Some times I dont even get a display.

^ remove the ram and try starting the system , do u get beeps ? if possible can u try a different ram chip..... and again , which PSU ?????

Done that I am getting the beeps. PSU = VIP GOLD 500W

-boot into the bios and try to run the ram @ 800mhz and check
-check another ram
-check another gpu

^in that order

Ok the culprit is the GFX card. I tested the same on another machine. This has been a rather strange issue that the card works for 10 seconds and the hangs up. Any way my card is currently under warranty so will try to get a replacement of the same. Guys thanks for your help on this.

^glad u figured out the issue. all the best for the rma and hope u get ur rig up and running soon !
