BSOD probably due to Graphics card
I launched assassin creed revelation and my PC just froze. After restart there was no bios screen but all fans were running and in my mobo only one LED was glowing(D1 was on and D2 was off and my mobo manual said that this is due to memory error). So I cleaned RAM and tried again but same problem. I removed graphics card and it booted successfully and works fine. So I guess the problem is with graphics card(HD4870).
And just a few minutes back I reinserted the graphics card and tried to boot. It didnt boot for a few mins but I just waited and after 3-4mins it booted. But there were some patches of pixels here and there on the screen. And while starting windows it crashed(BSOD). Due to the pixelated screen I could not read the BSOD properly. I again tried booting and again it didnt boot immediately but after a few mins and while loading windows again BSOD. I tried booting again and same result.
While searching google I saw lots of BSOD posted over here. So thought of posting. I think the graphics card is dying. Since the screen is pixelated I don't think the graphics card can be repaired. Or can it be repaired? I will be inclined towards repairing it if possible or else I need to buy a new graphics card. I am uploading the SF_Diagnostic_Tool zip file. Kindly confirm if the problem is with the graphics card alone or whether other components are also affected. Without the graphics card the PC works fine. No BSODs. So I guess only the graphics card is the culprit.
