Once again, I am in need of more PC help. Basically, I recently bought a Dell OptiPlex off of ebay to replace my dead HP Pavillion. It arrived today, I got it all set up, downloaded all the programs I wanted, and everything seemd to be working great. Then I leave it alone for half an hour. I come back, and it's off. Well, that's a bit odd, but not a big deal. I turn it on and try to log in with the user account I created. No dice. I try over and over but it doesn't work. So I log in with the old account name and password. What a surprise, it works. But none of my programs or documents are there. Darn. So, I change the name and password again, and restart, and it does it again. What is causing this and what can I do to fix it? Thanks in advance!
