I have been having random comp shutdowns, like someone pulled the power recently. This happened before, so I took the computer apart and reconnected everything then the issue went away for 3-4 months. Now its back. Now Im thinking could this be due to over heating, Running speedfan shows me that Core 0 is running at 52 degrees could this be the problem?
What components are you using? Could be a variety of things, try running some programs (or a stress/torture test like prime95) to put some high load on your CPU and see how quickly your CPU heats up. if it is 52C idle, it is a bit high but it's more the temps under load that you should worry more about. Your PC probably has an auto-shutdown feature that turns off your computer if the CPU gets to a certain level that will prevent any damage from happening.
