I got an XP Tip for ya!
Don't go messin with certain settings like bios and certain administrative settings unless you have System Restore on and have set a recent restore point!
I killed my OS! I couldn't even reinstall Windows. I had to install a brand new Hard Drive (which I just happened to have laying around) and set up my old 'C' drive as a secondary drive just so I could install XP and pull my critical data off of the 'C' drive. Then I had to reformat my 'C', delete the partition and then set it back up as my primary drive and reinstall XP.
Only good thing is that my system definately needed a good cleaning and it gave me the excuse I needed to finally partition my drives the way I want them. My system is running A LOT faster now as well. Anyhow, i'm back to gaming tonight!
