Computer Restarts Constantly

Hi

Having a weird problem. My PC started restarting by itself and gradually got worse to the point where it won't come on for more than a few seconds and the screen won't display. No consistency in when it was crashing, booting, gaming,idling were all possible.

I replaced the PSU (650w), replaced CMOS battery and reseated the RAM (16gb, tried individual sticks, in different slots) before conceding defeat. Sometimes it would stay on for a few mins, sometimes not, sometimes up to 30-40 mins.

I took it to a well regarded repair shop who ran it for 24 hours non stop and stress tested it. They reconnected all hardware and cleaned it thoroughly. They said it was working fine, just thought it was a loose connection or heat.

Got it home today and it restarted again in seconds. Tried different power cables to no avail in case it was that.

Any ideas what is happening here? Some sort of wiring voltage issue in my house or some reason it didn't break down in the shop? Very puzzled here so any ideas are appreciated. I have emailed them back so will see if they want it in again.

Thanks, Scott

Thanks, should have said. I plugged it in without peripherals all around the house and still the same.

Totally baffled but thanks for the reply!

I don't think so as they said it was the PSU to motherboard connection which is rock solid just now. Could reseat RAM again I suppose. Orientation is interesting.

No heavy loads in cooling or graphics. PC has been fine since I moved here a year ago and had it 4 years or so prior.

Yeah it's weird, like today it hasn't loaded at all but sometimes it would previously. Think it is getting worse. Kept thinking I had solved it with RAM or power. Very frustrating.

Now spent money on being told it is fine.

Getting an electrician out soon so will ask them if they can test the cables or whatever else they can for the sake of completeness.

Did you find anything that helped at all?

Just very frustrated/confused.

Yeah not super confident about removing mobo to be honest. Just don't get how it worked in the shop all day I even used a new power cable on it to check it wasn't something stupid.

Not knowing the issue is driving me a bit crazy but I'll keep trying

Yeah I had thought that a UPS might work. Got an electrician coming later this month to check something so I'll ask him then. Lived here a year without issue though and nothing else is affected.

I can get to the event log occasionally and it says Kernel Power and that the system shut down unexpectedly.
