This happens every morning or after any long period of time when my computer is off. I start up the computer and it freezes on the start up screen. The blue bar stops and it's appearance is different. It's no longer a segmented bar but like two hollow bars( if that makes any sense.) I then have to restart and the computer usually starts up fine. Every now and then it'll reset on the "WELCOME" window. Anyone have any ideas on how to fix this?

CPU might be heating up.... maybe replace the fan or heat sink i'm spent.. all this hacking is making me tired

or just vacuum all the dust off of the heatsink

Hmm, i also failed to mention it takes a very long time to start up. Probably a few minutes instead of the usual 30 seconds or so. Thanks for the suggestions. I'll post a reply about the vacuuming. thanks again.

Hmm, I did all the vacuuming and it didn't seem to fix anything. Logically, the heat shouldn't be a factor if the computer has been off for 8 hrs. I don't know, the computer will run fine once it starts going. I can turn it off for about an hour and turn it back on and I won't have these problems. Anyone else got any ideas? thanks
