I think it's my vid card...
About two weeks ago, my computer would just freeze up every now and then, and I think it mainly occurred when I was doing something video-intensive, such as watching a video or playing a game. It only happened maybe once every few days, so I thought very little of it. Now, it happens all of the time. I'm amazed I'm even able to type this message without it freezing up. It still mainly happens during video-intensive computing, but it takes a lot less for it to crash now.
I have an HD4850, Q6600, two sticks of 1GB Corsair XMS2, and I just tried a new PS, PC Power & Cooling Silencer 750W. I tried swapping the sticks of RAM, same problem, tried running the Windows 7 RAM checker, no errors.
I'm pretty sure it's a problem with my video card, as that would make the most sense, but I was trying the easiest fixes first before I had to replace my vid card. I updated drivers on the vid card, still same problems.
Any ideas? Or is it time for a new vid card?
EDIT: Sorry, Q9300. Don't know if that matters or not.
