Sounds like the guy who built your computer didn't do a good job. If he built it from scratch, with brand new components, you shouldn't be getting this corruption. If you recycled old parts with a new GPU, then you may have a cause.
I'm not sure what he means about an incompatibility, but if he knows that they don't work together, why did he put them together? Did you pick out the parts and he assembled it? Or did he pick out the parts for you?
I've only had this happen twice, once it was the cooling on graphics card dying, I set a room fan on full blast pointed an the open case, and it did the trick until I replaced the cooling. The second time is on a very old computer, but I haven't bothered to diagnose it yet.
Hey man! thanks for your suggestions/not going on a crazy rant - apparently my card is ugly
First of all, you guys having your fake/joke/not fake arguement, take it easy

hahaha, i don't want my shitty computer causing all this histeria!! (jks i kinda do. but not really. i dunno.)
In answer to your question: my old computer (which wasn't really that old) died because the graphics card just totally got busted. I was told by alot of people that my computer was fine but i just needed a new card (kinda an important part of a computer i guess

) so I bought my new card.
The guy just stuck the new graphics card in for me really. assembling computers is his job so i don't think he would have stuffed it up...
what he said exactly is actually that some people with my graphics card and motherboard combo experience problems turning the computer on, because for some reason the graphics card doesn't get enough power and therefor nothing displays on screen. He said that all these people had the same issues and the same solution - just turn the computer on and off. the computer wouldn't start perhaps one in 5 times.
ANYWAY, he demonstrated this to me, and sure enough what he said would happen happened when we were in his office. bout 2 weeks later this bullshit starts happening. now i can't get back onto him

and im not sure if he could help anyway - he's more of a builder/electrition then a computer genius.
Just so I know - what is the VDDC current exactly?
thanks so much people
