My Computer restarts every time I switch it off.
Here's the story: My computer automatically turned on few weeks ago when I was sleeping (I didn't set to switch it on nor tune the registry, etc.), and then every time I try to log off from Windows, it just restarts. Even though I push the power button, it just froze without turning off.
I've looked for many solutions on the internet (including Wake on LAN, unplugged all USB devices, tuned the registry, unchecked the box to avoid restart on system failure, and clean up the dust), but nothing works .
Is there any electric shortage? How can I know? How can I prevent it from restarting due to an electric shortage or software problem?
I built my computer about 1 year ago. This problem frustrated me recently; I hope it doesn't harm the hard disk. I need some help. Thank you very much!
