Computer wont boot up all the way.

Hello,
My computer wont boot up all the way. Right after the Windows XP pops up with its cursor bar below it, the screen turns black for about a minute and a half, instead of loading the uer login, this blue screen shows up with a message, "physical memory dump station" but my computer reboots itself before I have time to read it. The message is only there for about a second or two. It wont make it to the user login screen before rebooting. I have tried starting windows in: safe mode, safe mode with command prompt, safe mode with networking, start windows normally, and last known good configuration (your most recent settings that worked). The computer will not load anything else before restarting. HOW DO I FIX THIS PROBLEM???????? Before it started doing this, I started my computer up and windows wanted to run a disc scan or something like that, windows said I could cancel it, but was recommended that the scan took place. So i let it. After the scan, it starting deleting a bunch of stuff, like google items, and i think some window apps, I think. I wasn't really paying attention, it was 5:30 in the morning. If windows recommends it, I nowmally allow it. And thats when SH*T hit the fan. Can someone PLEASE tell me what happened, and what do I need to do to fix it? I am not a computer genious, so PLEASE HELP!!!!!!!!!!

Thanks to anyone that can help.
