The Computer has 2 hard-drives, one with windows 7, one with XP, both turn off right within 5 seconds of hitting the welcome to windows screen, I Eliminated heat as I re-seated, re-thermal compounded, and checked the temperature of the core. no problem there. replaces the PSU same result, changed all the internal cables, swapped ram, I am leaning towards it being either the Motherboard, or the CPU. however the system has no problem loading into safemode, it just turns off on both installations all though on different hard-drives, and the windows 7 installation has never had anything installed on it. The computer has worked for several months then, just these issues, Anyone?
Its a AMD Dual-core, 2 gig ddr, 2 hd's one Sata, One IDE sharing a ribbon with the DVD drive. It's not an overheating issue, I resank the CPU and re-applied thermal paste, the temp never goes over 42 when doing stuff, I am thinking its the CPU or motherboard, otherwise It wouldn't have the exact same problem on both loads of windows, since they are on seperate drives, one is SATA and one is IDE, and both windows stop right while loading and the computer shuts off, however I can enter safe-mode no problem, I would consider that the installation is messed, however not in both windows, and since windows 7 has been installed and loaded maybe 3 times, but nothing is installed on it, it does not make sense that it would be the installation, since I eliminated heat, the PSU and the ram through testing and swapping others, and the problem still exists that's, I'm just asking if anyone has any other Ideas before I get a new mobo and processor.
If you have 2 memory sticks, try each one on its own. Not sure if that will help, but it's easy enough to test that it's worth it. I also think a problem like that can occur when Windows tries to use the advanced features of the video card that it doesn't use in safe mode (not sure about on Win 7) so you may try deleting the video card while in safe mode, and downloading the latest drivers.
