To begin with I am a self taught (trial & errorssssssssss).
Recently a neighbor brought her computer over because of an internet e-mail problem. Because I was in a hurry, I just run a System Restore to 2 weeks ago.BIG MISTAKE!!!!!!!! Now at bootup I get a screen asking me to do a safe bootup or a normal bootup. Both give me a normal startup XP screen and then I get a blank screen and stays there with no more activity. I have reinstalled XP (repair) a couple of times with no results. No errors encountered on repair install. I don't want to reformat and reinstall unless I have to. She has no backups!! Any ideas what I can try to do without formatting?????????? BIOS problem maybe and how do I check if Bios working properly????

Computer is a VPR Matrix Model 1620 w/Windows XP Home.

Any help would be GREATLY appreciated!!!!!!!!!!!!!!!!!!!!!!!
