A couple of days ago my computer shut itself down without warning. When trying to start it back up it went to a black screen, after leaving it for a while it said that a certain sys32 file was missing or corrupt. I had to send off for a recovery CD as i was never given one. When it arrived i put it in and re-installed XP Home. After this i went to boot it up and on the first black screen of writing it came up Boot from CD: 'Disk Read Error'. I tried to re-install XP several more times and still i got this. I then turned it on and it went to the XP check disk screen (although i dont know how it came up). It took the best part of 15-20 hours to complete all 5 stages and it says some files had been replaced. So once again i boot it up and it goes fine. I get onto the desktop and start to reinstall some programs. After this it crashed twice and when trying to turn it back on it stays on a black screen and the keyboard freezes aswell when trying to get into safe mode. My most recent attempt and i havent downloaded any of the Auto Updates for XP because when it tells me to restart i do it but it crashes when rebooting. At the moment im catching up with a few things such as downloading Lost and Prisn Break but at the moment im afraid to do anything with it and i wont be turning it off again for a while. Any help is much appreciated.
