So it started last week when I woke up and turned my computer on and I found I was stuck at detecting arrays window I eventually got passed that (not sure how but I did) and I was able to use my computer not once did it freeze. The next day I turned my computer and it was stuck at the Windows XP loading screen, I waited for a long time but nothing happened even the lights of my computer didn't flash. So I have a few backups of the system on Caddy Hard Drives (I believe there called) I tried them all not any of them worked (I think unless I did something wrong) except for one that was a backup of a different PC which loaded up fine. (Unfortunately I was unable to actually use my keyboard or the internet despite being plugged in so I was unable to virus check my hard drive) I then used my original Master drive (The one that I couldn't get into) Then allowed me to get onto it and now works perfectly fine, I then got a message about a registry that was missing and was successful replaced. Everything works fine except for thee freezing. I'm unable to virus scan the C Drive (it freezes) I also can't chkdsk (freezes on 4% on stage 1) nor can I revert to last restore point. Overall I have no clue what to do
