My computer has screwed up twice in the past 3 or 4 days. It gets a bunch of lines across the screen starts making weird noises then gets a blue screen. When I shut it down and turn it back on everything works fine.
Done all Windows critical updates?
Suffered from any viruses recently?
Scanned for viruses?
Have you made any changes to your PC that started these blue screens?
At the end of the day, your OS could just be failing. I would start backing up everything you want to keep and do a re-format.
