If not mobo caps then PSU, rootkit, failing driver or service in that order.
Check the PSU with a DMM. Scan for viruses IN SAFEMODE. Check the Event Logs for unusual warnings or errors at startup/shutdown.
Safemode working points at infection or driver/serivce issues. Bobby Heid wrote:
Hi all. I have a friend's HP pc (P4-3Ghz, 1.5GB RAM) running XP pro. Starting last Friday, it would not shut down for her (it would hang). Then it decided it would hang on startup. So I went over to look at it. I could boot in safe mode (and shut down also) with no problems. I brought the pc home and restored it to a prior backup from about a week ago. Now, it seems that I can get it to work properly (most of the time) if I do a restart, but it hangs on startup if I start from being powered off. I have disabled all startup items from msconfig, dabbled with services, but to no avail. I've tried using "last known good configuration." and it works sometimes. Anyone have any ideas as to what may be going on or have any ideas for me? Thanks, Bobby
