My grandfather's PC was shutting itself off, and based on my previous inspection, I thought it could have been a bad PSU, since the PSU fan was barely spinning, while the CPU fan was working fine. So, I ordered a new PSU (a Cooler Master GX 450W), which should arrive soon.
However, I decided to disconnect and reconnect the PSU to the mobo, and now the PSU fan works fine, but the CPU fan isn't spinning at all. Perhaps I was thinking the PSU might have shifted its power from the CPU fan to its own fan.
So, what you think the problem could be - the fan itself, the PSU, or the motherboard? The motherboard is a Gigabyte GA-8IG1000MK, and the current PSU is a cheapo Dinamax 450w model.
I really hope it isn't the motherboard. FYI, at least the motherboard does seem to detect the fan not spinning when I enable the CPU Fan Fail Warning in the BIOS, so hopefully this is a good sign. I already ordered a new PSU, but if the fan itself is the issue it shouldn't cost much to buy.
