My computer has been resetting a lot especially after I use it for a few hours. I think it may have to do with the power supply or temperature issues. The PWM temperature sometimes reaches 56-57 degrees is this too high? Would it cause the computer to reset itself?. I've also gotten Stop 0-x00000050 and stop 0x0000007F. With error messages of page fault in nonpaged area and mismatched kernel and hal image. Please help!

Thanks,

Rob
