Need a replacement graphics card?

[Sheepdisease]

Hello, I have suddenly started having major problems with my PC since I replaced the thermal paste on my CPU and liquid-cooled heatsink for my GPU.

 

I'm not quite sure what I have managed to do, but my guess is that the graphics card is screwed. My motherboard does not have on-board graphics to test this theory. When I booted up having removed all the old paste, replacing it with much better stuff, it loaded up Windows 7 like normal. When the desktop loaded, it was all fractured (parts of the desktop appear fine and others completely messed up/randomly). I restarted the computer, because on top of this, the computer froze up, This happened a few times, before finally I restarted again and the computer booted-up, got to the loading Windows screen and after that, made all the usual sounds (internal) that would suggest it was still loading up into Windows, but my monitor displayed nothing but a blank screen.

 

Any thoughts? If it is the graphics card, can anyone suggest what I can replace the BFG 8800GTX OC2 768MB GDDR3 Dual DVI HDTV Out HDCP enabled PCI-E Graphics Card with, running on a Corsair 620W HX Modular PSU (ATX12V v2.2 APFC)?

 

Thank you so much for your consideration!

Hello, I believe we have met somewhere else lol, I suspect heat but will leave the tech's here to suggest more, as they may have a different idea's ;)

Hello again, yes we have me elsewhere! Thank you for your response.

Hi, I can only ask if you kept in contact with the case while doing the renewal of the heat paste, and also that the machine was definitely not switched on as I suspect static damage, hopefully only to the graphics card, but you never know. The only way to be sure will be trying another GPU card in it.

I would suspect the RAM sinks on the underside of the GPU are not contacting the GPU waterblock :)

Hello,

 

thank you both very much for your responses.

 

Nev, when I was applying thermal grease I had grounded myself and was careful not to touch areas of the card which are sensitive to static (picking the car up very much like one would pick up a cd or dvd carefully from the sides).

 

Dalo, blue pads came with the water block and these were adhered to the RAMs when I attached it to the graphics card.
