The only pertinent piece of hardware for this problem is my motherboard (ASUS P5N-D, BIOS revision 1401), since it is the only piece of hardware that has changed from before this problem appeared. Every other piece of hardware is exactly the same as before, the only changes that had happened to the computer are several installations of Windows Vista and 7, but that was after the problem appeared (1 reinstall of Vista and 3 reinstalls of 7).
Here's what's wrong; I had a computer and everything was working fine until one day the BIOS chip died. I sent it in for repairs and after I got it back restart didn't work anymore. What I mean by this is that restarting Windows from the Start menu, after installing updates/applications, even during Windows installation would only go half way, as in shut it down and then freeze before powering back up, forcing me to either perform a reset or hold the power button for 4+ seconds to shut it down. The fans keep spinning and NumLock is on, but the computer is for all intents and purposes powered off (no signal to the monitor, no HDD activity,...).
I have reset BIOS (in the menu and also by removing the battery), updated it and nothing helped.
The power & reset buttons and shutting down the computer from the Start menu works flawlessly. Also, if I restart from BIOS it works, but that is the only instance so far in which case it worked.
This is what I know:
It is not a PSU, temperature, compatibility or Windows issue. I am 99% certain it is something involving the motherboard (BIOS, jumpers,...), I just don't know what it is.
I've had this problem for a couple of years now, but after I bought 2 WD Raptor HDDs for Dual Booting Win7, it's getting pretty annoying having to shut down my computer every time I want to boot into the other OS.
