I am attempting to run a reinstall of Windows 7 for a friend. The system boots and gets into the Windows install, though when it gets to Expanding Files ... 75%, the system acts like it is rebooting and then shuts off. I have thought about that it could be bad RAM or HDD. Though the times that I have seen that it would give some sort of error code first. I also though that it could be the mother board overheating. Though wouldn't it just shut down not try and reboot first then shut down. On top of that wouldn't it need to cool down before it would work properly again. Have you heard of this? What did you do? Got any ideas?
