My computer keeps rebooting every 10-15 minutes...why would this happen for no apparent reason?
Maybe a heat issue or bad psu. It`s hard to tell from what you have or should I say haven`t told us.
Please can you be a little more specific? I.E when did this problem first occur?
What is your psu? and what OS are you running?
Have you recently installed or uninstalled any hardware/software etc?
