I can start the computer up fine in safe mode. I’ve used the system restore feature from a couple of dates going back a month or two but I still get the same problem.
The weird thing is, after booting into safe mode, if I don’t use the auto re start after a system restore or just exit out of the safe mode and re start in regular mode, windows will start up fine about half the time. If the computer boots successfully into a windows sesscion it works fine, that's how I'm posting now.
The problem seems to have started after being on line, clicking a link that tried to load up a PDF file in the internet explorer and froze explorer up. I cleared explorer off with the task manager and re started explorer fine, about 5 minutes later the computer just re booted it’s self and then the next time I tried to start the computer the next day I started getting this problem.
