CPU fan probably seized, is it hard to turn? If so that is definitely the issue. Mechanic issues are usually the problem with PCs.The CPU fan isn't spinning when I turn the power on on the PSU and since the PC doesn't respond to the power button it doesn't start spinning then either.
The Motherboard does light ub with the amber lighting which is on this model, so it is getting power when I switch the PSU on. I can also see a light turn on on the GPU, next to the 8pin or whatever it is, signalling its getting power.
Couldn't find any residue on the MB as far as I could tell and tried swapping the connections for the panel power and reset button but didn't work either.
I'm wondering whether I should take the CPU fan off and take a look under it, but I currently don't have any spare thermal paste at home so don't want to be taking the fan off before I can replace the thermal paste and put it back.
