That will cause immediate problems if this is being seen on a brand new build or you added additional memory in lately. You didn't fill out your system specs or provide that information that might be a help here in solving the problem.

Note that problems with power supplies while most of the draw is seen during the post tests can also play a role. If the board is a year old+ you may have to replace the battery on it as another possible cause. Once a battery becomes weak you will tend to see sudden restarts out of the clear blue! Eventually you will press the power button one day and then see nothing! when a battery goes completely.

These are some other things to consider before assuming any hardware fault being realized.

I think I've solved the problem. not sure why vista didn't have a problem.
I tried different memory settings, did not help, tried increasing memory voltage did not help. What did help was lowering the FSB frequency from 333 to 332. with 333 memory was slightly overclocked by default. with 332 it is 1 Mhz lower.

That would suggest it was still memory related but not for the same reason as finding a bad dimm or mismatch. By lowering the memory clock a bit it appears all the memory installed is now keeping pace as it should with matched timings.

The 332 x 2 = 664mhz still applies. But at least you made some headway there.

That seems to be working out for you there. Since you found things more stable with the slower timings that suggests the board is a little particular about what memory goes on.

I noticed the memory was at 2.1v in the text file you added. Have you tried changing that at all like dropping it to 1.9-1.95v? Memory will tend to run cooler with the lower voltage setting.

I want to test my system for a few days before trying something.

I can readily agree with that. Presently the 4gb of PC2-6400 memory used here stays at 1.8v 4-4-4-12 2T and has been doing well since Dec. 2008. CPU-Z shows the 1.8v there. That's DDR2 800 however that will run that low.

Otherwise at least according to someone at the Corsair forum and as long as your cpu supports the speed you simply load the optimal defaults in the bios with the 2.1v for that memory to see 5-5-5-15 2T

Mostly this was a problem seen with the 64bit Vista seeing reboots due to an incompatibility with hardwares. But you also saw problems simply getting the older 64bit Windows on with more then 2gb installed as well. The only other to look at would be the HPET setting there to see if that is enabled. Otherwise see how it goes for now.
