1. Computer HANGs or RESTARTS on its own.

a.       Probably a computer VIRUS.  Remove the virus or scan and clean your computer with the Antivirus of your choice.

b.      Your operating system is corrupted. You need to repair it but reinstallation is the best solution.

c.       The software or process you are running is corrupted or might not be compatible to your operating system. Reinstall the software.

d.      Hardware defect like Memory and Video Card so you should check on these. Try reinserting these hardware.

e.      Defective ATX Power Supply. Have it replaced or change with higher wattage.

f.        CPU overheating.

Solution:

- There's a build-up of dust in the heat sink so detach the fan and heat-sink then clean.

- The CPU fan is not turning or turning slowly - Clean the fan and put motor oil (not cooking oil) or grease on the bearing. The bearing is at the center of the fan covered by a rubber or a hard plastic. Replace the fan if it still doesn't turn. I recommend high quality cooling fan with at least 5000 RPM.

- If you had overclocked the CPU, reduce the overclock speed. Better you configure within the rated limits.

g.       Check the Video Card, if the fan is not turning then do solution above.

h.      Hard Disk (HDD) overheating. Put extra cooling fan above your hard disk.
