XP hangs on loading ACPI - reboot loop - could it point to bad PSU??

[bucketwater]

Thanks for replies ahead of time. No luck loading XPPro in safe mode or normal. get a continual reboot. sometimes it was getting further along than other times during the 'windows loading splash screen'. Thought it was a drive issue, threw in a new empty drive. Was able to get XP up and running. Came back to computer later to find it in a reboot loop.

I enabled boot logging and took a look at the boot-log file through bitDefenders knoppix/linux recovery OS -
Drivers seem to load up until:

Did not load driver Advanced Configuration and Power Interface (ACPI) PC

Thus I am wondering what the issue is with that driver and windows. This is now occuring dually in a fresh XP install on a new drive, and on my old drive that was originally in the computer.

When I set windows to go loading the last previously successful configuration, the PSU makes a terrible noise, however, it doesn't make this noise until that choice is selected.

For instance right now I have booted into knoppix via BitDefenders boot cd... and the computer is fine with the PSU not making any weird noises.

Thoughts here? Before this happened I did not upgrade ANY drivers, install new software, OR hardware.

First a list of your system componets may be helpful.

Before you get to the XP splash screen hit F8. It should give you a list of options. Select the option to "Not reboot computer on error" (something along those lines). If it's not a power issue but rather a blue screen event, your computer should stop at a blue screen with a STOP Error. If that happens, post what the STOP Error is.
