Recently my gaming of has been acting up. the first symptom was all pc fans starting except cpu fan, then the pc would shut off and restart and all fans would spin . Second issue, freezing screen after a few minutes on my pc, only solution was to restart pc. Third and final issue, pc starts but doesn't display to monitor after boot menu. My pc is unusable. Do I have a cpu or motherboard, or even power supply issue? Any help is nice.
