I have been having the most frustrating issue with unexpected shut downs and I need more opinions. I had a liquid cooler AIO break recently - small leakage - and when it started to malfunction a whole new problem arose. The cooler probably damaged some parts, but I need to figure out which.
What is happening is I can power my system up and usually I can let it run for about 20-30 minutes before it powers itself off and when it does only the power button LED remains lit. When the system shuts off if I press and hold the power button - like a hard shutdown - the LED won't go dark. If I go and flip the switch on the back of the PSU to reset the breaker the LED will go dark and the system is ready to power up again.
The issue is inconsistent - sometimes the machine will run for 20 min before it powers off and other times it will do it before windows even finishes loading.
Now normally the first reaction would be to look at the PSU since I have to reset the breaker, but I have come across some things which indicate more may be involved such as fluid getting onto my board.
In this thread here the guy is describing a very similar issue, the only real differences are his system can run up to 45 min. before shutting itself down and he will have a residual power letting one fan temporarily spin after the power off. Mine doesn't do that, when it happens it is a straight up power off leaving only the power button LED lit. His issue turned out to be his motherboard either due to faulty VRMs or power control circuitry.
Then I saw this youtube video where a guy is talking about the same issue I'm having - no mention of the power LED staying on - and all of the usual hardware suspects checked out. Turns out the mobo was warped and the cpu socket was separating from the board and he demonstrates this with a straight edge razor. What caught my attention was when he stated the motherboard was getting to a certain point with temps and then just shuts itself off. This kind of sounds like what is happening to me.
I haven't used the PC at all since this started happening to prevent further damage to components, but the last time I did turn it on I was looking at temps within HWInfo. Cpu [with stock air cooler] was fine between 18-23 C, general motherboard temp was 30 C, northbridge was between 40-42 C, and HWInfo under the motherboard section has individual listings for "temperature 4, 5, 6" which were around 45 C. I launched Rise of the Tomb Raider, played for about five minutes, and about three minutes after exiting the game is when the shutdown happened. I didn't get to see mobo temps before it happened.
If it really was just the PSU after I flip the switch I would assume the breaker would need time to cool down and reset before being ready to power on again. When I flip the switch it's ready to power up immediately.
Parts are going to have to be replaced and I need to get the best idea I can what is at fault since I would hate to go and buy another PSU when it may not be the problem. I have limited resources so I can't test the PSU or mobo with a multimeter, but I figure one of them is at fault. The question is which one is it?
