It looks like you have had a hardware failure at the most inopertune time. Most likely the computer has devekloped some bac sectors on the hard drive right in the area where Windows has the boot up programming. To test this i would use a Windows XP CD to boot up the computer with and see if the computer will get to a desktop that way. If it still does not get to a desktop there are some hardware failures that could cause it. Memory that is going bad could cause it. Again, the hard drive losing sectors could cause this.
A repair install may fix the problem( but i doubt it).http://www.geekstogo...ws-XP-t138.html
If the repair install does not work it is time to start replacing hardware until the problem is fouind. Memory replacement is first( cheapest and easist). Maybe just checking the memory in another computer or using memtest 86 to check it will tell you. If not the memory i think it is the hard drive and replacing it would tel you if the drive is going bad. Every HD maker has utilities to test the hard drive if you want to look in the computer for the drive maker. go to the HD makers website and download their diagnostic software and burn it to a CD to run on the computer. Yhat will tell you if it's bad.
Sorry for the bad spelling. It took a day to figure out the wireless was being blocked by a hard drive i carelessly left next to the receiver.
