Plz help...I built a new PC and everything is well except the OS (I think). My PC would restart every once in a while and an error report would be sent right after it booted. Microsoft's crash analysis said that it was caused by a driver problem. I tried reinstalling several different drivers, updating the drivers/Window, and I tried scanning the hard disk for file corruption...etc but they all didn't help. Some times when the PC reboots on its own it display a message right after the POST saying there is a "missing or corrupted file in system32\...." (don't remember which file it was, but it was a .DLL file) and told me to replace it. If that is the problem how would I reinstall that file? Thanks.
