I came in this morning to get on my computer like usual. Windows was stuck,(it was running fine when I left it and I didn't shut it down) It was basically showing the desk top background but that's it. No icons or anything. I rebooted told it to start windows normally and windows booted to the desk top. But it was very sluggish and then froze up. I restarted but this time told to to go to safe mode. It behaves as though it's going to safe mode. Black background loading system files needed etc. But it stops. Never boots into safe mode. I tried telling it to boot normally again and it did. I tried to do system restore but got the error message saying the drive had errors and needed to be checked and fixed. So I scheduled it and restarted. Acts like it's going to do it. Says it's going to scan disc unless I push any key to stop it. I don't touch anything. Check disk pulls up but does nothing. It crashes after like 2 seconds so no check disk. It then boots into windows and the process starts all over. What could do this and how do I get out of it?
