The computer will just randomly do a windows shutdown and then restart. Cleaned, changed the power supply and still does it.

    As I said it just does a windows shutdown, as if you click start/shutdown and then restarts goes right back to windows. Does not stay off, I would think a heat problem would make it stay off or immediately shutdown again, which it is not doing. Also it can just be sitting on not logged in and will shutdown.

Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the computer back on and figures out a way to foil the protection, the unit is probably doomed. Once a unit shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated unit is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning. Check the CPU fan if it is spinning and also the CPU itself put thermal paste. So that the heat from CPU will absorbed by the heat sink.
