THanks for the reply. I already determined the psu was causing issues (not enough or inconsistent power because of poor connection)
I bought a pcp& cooling 750w 80+ silver to replace it, I'm also swapping out the CPU (i7-2600k) because it was only running on 1 core 1 thread according to cpuiz....
My question is did the psu damage the mobo, and will that damage my new CPU? (all components are new)
Thanks again for your help.
The motherboard has safeties and will sacrifice itself in order to save the CPU. This means that if the motherboard is functional, then all is well. Good that you got a new PSU.
When you install the new CPU make sure that no pins inside the socket are bent.
