I installed Win 7 32bit on a clean system yesterday. And I just got a spontaneous reboot after only some browsing/downloading, nothing harsh on the system.

Installed a few apps and 1 game, 1 video card driver for my x1950 which isnt supported anymore by AMD on Win 7, and thats it. I already noticed a weird stutter, where the system would just freeze a second every 10 seconds, for a couple of minutes, it stopped, and another couple of minutes later it crashed.

Well, I had another one this afternoon when I was burning Win7 64bit, it failed and just rebooted, my DVD drive freaked out and started spinning continuously, plus it wouldnt even eject. I had to reinstall the DVD drivers driver for it to give me my CD back, but thats not really related to this I guess. I have been having a similar issue with my newly constructed computer, and I would be very curious if there has been a solution fleshed out. The error seems to happen more frequently when exercising the 3D hardware (e.g. I've updated the motherboard firmware and drivers, video card drivers, and integrated sound / ethernet drivers in an attempt to fix this problem, which has so far been fruitless. Interestingly, the spontaneous reboots only started occurring after I updated my motherboard firmware to the latest version (as the version that comes with the Gigabyte GA-m790XT-U4DP doesn't recognize Phenom II x4s by default, and sets their frequency to 800Mhz rather than the 3.2Ghz the chip is supposed to be running at). 7 I have about a dozen of logs mostly identical to the one below modulo the time at which they occurred. I've attached the most recent one in hopes that it provides someone else more edification than I've had.
