- Windows WILL start up just fine if the computer has been sitting OFF for at least ten minutes.
Things I've already tried:
- Reformatted the HD and reinstalled Windows XP
- Tried a fresh install of Windows XP on a different HD
My half-cocked theories:
1. Could one of the system and/or boot files be corrupted? My guess is NO because this would also affect a normal cold boot shouldn't it?
2. Is there a component either on the mobo or in the PSU that is locally overheating? If so, it would mean then that said component is only needed during boot up. In other words, it does its job during boot and then is no longer needed. After a cold boot (which so far has always been successful) that component would then be too hot to work properly for a restart.
