My pc freezes seemingly randomnly, some days not at all and some days multiple times in a row. I will be on it and all of the sudden I can't do anything, screen does not go black or blue or anything, it literally just freezes where it is. Because it does not blue screen there is nothing in the dump files I can look at to give me a clue. I ran memtest last night and it came back with no errors. Drivers are up to date. This was happening before I upgraded some parts and after so I am led to believe it is not from any of these parts: CPU, mobo, GPU, Hard drive. I keep cpuid or hwmonitor running to make sure it is not overheating anywhere and I haven't seen anything above 40 degrees celsius. I really have no idea where to look now. Has anyone seen this before?
