Usually right after I turn it on. It will run normally for about 10 minutes and then just reset itself, giving me a blue screen (which goes away so quickly I can't see what the error is), and then run fine for a while, only to reset again. Does anyone have any idea of what's going on or how to look up what the error is?
I've had issues with this PC overheating in the past, and I'm wondering if also maybe it's related to the external hard drive (which is not on right now) or external DVD burner I have hooked up via USB.
