My computer running Windows 7 suddenly starts behaving very strangely. If I leave it idled for a while, it automatically logs off and restarts. After that, it may or may not restart successfully. What I mean by that is that when the manufacturer's logo appears when booting, it shuts down and restarts again.
I don't know if this is a hardware or software issue. Does anyone have a clue of what's going on? I know what I am describing here is vague, but that's all I can provide.
