I've had this Windows 7 laptop for about a year now.  It actually just got back from the repair after a major hardware issue that popped up out of nowhere.  It should be working fine now, except it suddenly BEGAN to act strange again.  Just yesterday, it crashed twice.  I think it was during a video, but the screen suddenly froze and after waiting a couple minutes it crashed.

The next problem is when it starts up.  It starts normally with the windows logo, but never gets to the welcome screen.  I hear the windows greeting noise, but the screen remains lit up and black.  After waiting for a few minutes, I pressed the power button until it shut down, then turned it on again.  This time it started normally.

What worried me more is that TODAY, all my ACCOUNTS were logged out.  Normally I keep my email and other account passwords saved and kept logged in (when I open up my email, I'm already logged in).  The passwords are unchanged, but all my accounts were logged out.

Is this serious?Please define "crashed"Went to the screen where it said "dumping data" or something.  It started up pretty quick after that, so I couldn't really see what it was. Quote
