Hi,

my pc seems to trun off whenever it feels like it, and when it does i have to unplug it from the mains and then switch it back off,

some times the monitor goes all fuzzy and the computer crashes and has to be un-plugged from the mains to be reset

i thought it may be heating issues, i dont have a case fan but will be getting one, i ran speedfan and temp2 and temp3 showed up as 72 and 52,

any advice will be greatly appreciated,

thank you

Hi it sounds like a power supply issue to me. I't sound like it is overloading and that's why you have to unplug it and plug it back in to get it to boot. Change the power supply first.
