Troublesome BSOD

If anyone could give me some suggestions other than contact Dell Support! I got the Blue Screen of Death when I just turned on my computer. It was working fine the day before, but I remember installing a new program for my PDA. Here's the code: Stop: 0x0000007b (0xF9678528,0xc0000034,0x00000000,0x00000000) I'm unable to get into any type of safemode or last config. I've tried to reboot w/ my Window's XP CD, then do a repair and get into the Windows command screen to run a "chkdsk /f" as it states to do on the BSOD. I could only do a "chkdsk /r". Not sure what my other options are or how to do an actual repair of the installation. Please help, I don't want to reload XP and wipe out my drive cuz I didn't get to back it up w/ my external HD and I'll lose alot of personal data (family pixs, mp3's, school documents).

I read up on this forum and other forums and found out how to do the repair by rebooting XP. Please delete this thread.
