My PC just started randomly restarting, and then sometimes freezing. Heres the weird part, when it freezes, i cant turn it off. even if i hold down the power button or press the reset button. I have to turn off my power cord in order to restart my PC. And when it freezes my speakers make a weird constant noise. I think its my Motherboard. Because all of the symptoms are directly connected to the motherboard.
All my CPU and GPU temps are normal. I even turned off all overclock setting back to normal. and still i get these problems.
any ideas what it could be?
