I have a computer here at work and the CPU is idling at 41 C I know this is way to high and the PC continues to shut down. There are no signs of dust visible and the RAM is good on the machine. There are fans at the back of the computer and on the processor. Also I have the side cover off. However the PC is still shutting down. What can I do to stop this from happening? Motherboard issue? Power Supply? Please inform
