Um, ok really big problem. Once and a while for the past week my computer has just decided to shut down in the middle of something (usually Sims 2) and this blue screen with white writing comes up saying something about the computer shutting down and doing some kind of memory dump I think. I don't know exactly what. Before that, I've been having a problem with the machine randomly restarting for the past few months (I already updated my drivers to fix this, but it didn't really HELP). Now when I turn on my computer, it goes onto a screen with a countdown from 30 asking me whether I want to start up from safe mode, start normally, or revert to last known working setting. Whatever one I pick, it goes to the windows is starting up screen. then, all of the sudden, the computer hum gets a little quieter, and then it goes back to the gateway screen, then back to the sceen asking me how i want to start up the computer. What the heck is going on?! I'm sorry this is really long, but I don't know what's important and what's not. BTW virus, malware, and spyware scans during the last few months found no major problems. Also btw, I am a computer idiot and will likely understand little to no computer jargon used.   Any help appreciated. Quote
