Hello, My computer gets to the windows screen and then shuts off. i can get it to usually load into vista after letting it sit in the bios settings till the system temp reaches 31 degrees celcius, but after a while the computer will shut down randomly and it will always load right back up into windows. i just cant seem to start it when its cold for some reason. ive changed out the ram and tried different sticks in both slots and neither has affected the issue. i tried putting in a different hd but it just goes to blue screen and restarts. i cant load into safe mode or have the system check for errors unless like i stated earlier it just turns off unless it hits the right system temp.
That is a strange one all right. I would start off by swapping out the PSU. If that doesn't work I would pick the motherboard as the next most likely suspect. I would definitely start with the PSU however.
