Everytime i start my computer the little bar that runs accross the screen freezes and i have to pull the plug at the mains. When I turn it back on it say "windows is sorry for this error and we believe a recent set of software or hardware may have caused this" I choose start windows normally and it crashes again, I have to do this 5 or 6 times for windows to load. Its only started happening recently and I havent installed anything new really. I ran a check disc and scanned for viruses but nothing was found.
Any help would be appreciated.
