Windows 7: Display constantly freezes after RC1 install

I was using the Beta since Feb. with no problems whatsoever. When the time limit was up I installed the RC1. I did a freesh install, not an upgrade. Ever since the install, my display will freeze at random and the pc requires a hard reboot. I initially assumed it was a video driver issue. First, I updated all my drivers to the latest, but it kept happening. So I tried the driver for Vista, but it kept happening. Well, gaming and watching video is the main thing I do with my pc, so as is it is useless. I disabled the video driver so I could download another OS but it still freezes, even with no video driver.
I can't stay unfrozen long enough now to download a linux distro, and my XP is no good becasue it doesn't come with the drivers I need to get online, so I can't install it and update the drivers, so basically I'm screwed.
I have searched online for hours, but no real answers. Its frustrating as hell that the beta was working flawlessly, then they made me ugrade, now its broken.

Hello Nitesmoke, welcome to the forums.

You might try one of the newer builds, such as 7264. If you want a link, PM me.

I was actually re-downloading the beta and was going to use some "methods" to get it working past the 2 hour shutdowns. I'll try the newer build firts, though.
