I don't mean to alarm you but if the same thing would happen to me with a gaming computer I would panic.
I would like to know what the command prompt says, but since you can't tell me, my educated guess is that there is a hardware or OS malfunction.
If I were you, I would first try to reset to factory settings. We at CCM have faq on how to reset almost all computer brands to factory settings except Cyber Power.
