Windows XP crashed (I think) during a system restore. When I reboot XP appears to be loading then the screen goes black. It is a Dell pc and Dell helped me run extended diagnostic tests and found nothing. I cannot get into safe mode either. They had me run windows reinstall/repair and it all looks good until the computer tries to restart, then back to the black screen after XP starts loading. Dell's next step is to wipe my hard drive clean. I have been told to put my hard drive in another computer which is not an option, I have also been told to try using another account to log in as it seems the user account settings are not loading due to a profile being corrupt, but I am at a black screen and cannot log in. Someone else said registry problems. The general opinion is not to clean the hard drive, which I hate to do, but what do I do next?
