Lately, my desktop has been freaking out on occasion. It results in a complete freeze of the computer, and a white screen, or a black screen. It's also happened on a more mild level too -- then my desktop recovered and claimed it was a video driver crash/recover. This forces me to power down my desktop manually and reboot it, and upon reboot, I don't get the "windows has recovered from a serious error" dialog box.
At first I thought it was my RAM (no idea why, but it was worth a shot), so I tried all of them individually and what-have-you, none of the RAM was at fault.
I figured if it was my CPU, worse mojo would be happening than this.
Then I was like "well duh, one of my video cards is overheating." Except that isn't the issue, because when it freezes, I open my computer case and touch my video cards. They're both nowhere near hot enough to overheat.
After that, I figured it was my drivers, so I removed and re-installed them completely, and just last night it happened again.
I'm running windows 7 ultimate x64 with an ATI Radeon HD 5670 and an ATI Radeon HD 4300/4500 card.
Has anything like this happened to anyone? I googled around but didn't get many results.
