I have just built a new system with the above specifications and I am having problem where windows would restart immediately after or before xp logo shows up. It appears to happen if the computer is turn off for 1-2 hours. If i reset or turn off and turn on again, windows would start normally. It is an intermedently problem that i cant seem to pin point the causes. I have even tried and built a second system based on the same specs-model-brands, the restart problem still occurings.

Could it be that psu is under power? How could two exact same computer built with the same part, experience the same problem?

Got a link to where you bought the ram? And how much, in what configuration are you using?

And yes, that PSU may not be enough for your card. What is the 12V rail on the PSU and what does your card require?

The 430 watt basic thermaltake psu can provide +12v 18a under max load. What struck me is that psu is not even at max when windows is loading but why windows is having problem loading. When windows has successfully loaded, the computer seem to work fine without any reboot, lockup or freezes. It only happen during startup out of 1 in 10 turn on. I know it is not driver problem.

On the box it states that mininum requirement is +12V 26A

Two gig of cosair value ddr2 667 Mhz 2 X 1GB
Regarding the ram, it is set at auto settings. I have never had any problems with ram at auto settings with other builds.

Well that is your problems there then. Your card needs up to 26A and your PSU only can give out 18A. That card plus all your other items is for sure maxing that PSU out

Ya, Auto is likely fine with that ram. I just asked incase you had 2x2GB or 4x1GB

I would suggest you buy a much better PSU for each system. A PSU is the MOST important part of your system, and should never be skimped on. You should get one with at least 30+A and 500W, the wattage is not so important but the 12 rail amps is for sure
