When is the last time you took your computer apart and cleaned out the ‘dust bunnies’?
Check the vents on the powersupply, processor exhaust fan and on the front of the computer for dust plugging up the works.
It doesn’t matter if you are in an air conditioned environment. Dust will cause your CPU to overheat.
Also pull the heat sink off the CPU and clean the dust out of there too.
Most of the ‘error’ codes you get are too cryptic to be able to pin point a program or process that may be causing it. They are generally caused by a ‘memory’ error because of heat build up. (some times it’s bad memory too, but not likely)
Also try re-seating your memory and any expansion cards you have plugged in.
Good advice from Bigh4u2 in that hardware is the most likely culprit, and memory the most likely source of hardware problems other than oddball USB devices.
Overheating - I don’t think so. Modern CPUs/mainboards have overheating protection and will slow down and/or start beeping when they get too hot.
