I had a hard drive that seemed to be faltering. WinXP would freeze for a moment or two then resume. Also, recently, whenever the computer would reboot, it would automatically run chkdsk. I installed a new hard drive, a few moths ago and cloned the os to it using Acronis. Before switching over to the new drive, I thought I'd try throwing in a new power supply that I had laying around, thinking it might be a power issue. I went from an Antec 500 to 650. I am now getting the 0x0000007E BSOD error when trying to get into WinXP normally. This occurs no matter which hd I boot from. I ran chkdsk /r on both hd's and did a fixboot on them both as well, nothing. Prior to that I booted from the XP install disk and ran the repair module. I also, unseated and reseated my video card. No luck. I am able to boot into safe mode. Not sure what to do next.
