Computer ran very hot, shut down, won't boot back up
7 replies, posted
So my step son's computer is a water cooler pc with low-mid end parts and he doesn't do much heavy gaming but recently it had shut down without any warning and won't boot back up. I switched out the power supply and still no luck.
Also checked the CPU and it's not melted as far as I can see and the thermal paste looked alright. I was thinking maybe it is the motherboard but I need help troubleshooting.

Run through a troubleshooting checklist like this one first (including barebones test) then report back if you still haven't found the problem.
Thanks, I'll let you know how it turns out
In what way does it refuse to boot? Does absolutely nothing happen when you try to power it up? Does it start but not POST? Does it turn on and then shut down again shortly afterwards?
And how did you conclude that it 'ran very hot' before dying?
It should also be noted that there are fail safes for components such as the processor, if it runs too hot (~90 Celsius for most Intel ones) the frequency will first be reduced, if that doesn't solve the problem and it continues to heat up, exceeding 100C, the system will shut down to prevent damage, sudden death from heat is sort of impossible, or at least very unlikely.
Feel free to poke me in PMs if you need any assistance, or update the thread and I'll pop back in and try to help.
Your liquid cooler probably leaked. What model is it?

If it's an AIO, occasionally you can make a warranty claim to a manufacturer and they'll reimburse you for new parts
Hey guys, sorry for being away for so long. Have had a lot going on and just now got the time to check his rig. So using a second working PC I switched out every part in his non working rig and checked it in the working rig. Everything seemed to be fine and the last thing was the motherboard. So I'm going to buy a new one and some fans and use Core Temp to monitor his temps for the next few days once it's working again.

It could have very well been the cheap motherboard that was used in his rig seeing as it was a prebuilt pc, when I get the new one I'll check his tower for any loose screws or contact points that may have shorted it. Also to explain how I knew it was running hot is prior to the event I noticed his room was very warm and his pc felt warm on the outside while idle so I can only imagine how hot it got with games. I was going to keep eyes on it but the next day it had died. I should have shut it down earlier.
Depending on the size of the room, even mid tier gaming pcs can efficiently heat your room. In the winter I pretty much just use to use my PC to heat my room but keep the rest of the place colder because heating is fucking expensive (and this was especially effective back in the mid 2000's when Nvidia cards earned their meme status of being hot as shit). Also water cooled builds "put out more heat" in the classical sense because they're more efficiently dissipating heat from the pc outward. Water cooled pcs, unless you're putting the radiator in a window or venting it out of the room otherwise, will [I]never[/I] make the ambient temperature of the room feel cooler than an air cooled pc will.
As to the case being warm, depending on if the prebuilt was engineered to use the case for passive mobo cooling or something like that, it'll be a bit warmer on the outside, but if you're using it far out of spec then it could very well get annoyingly hot, probably not the problem though as the case can be warm to the touch in parts but the mobo may very well be perfectly fine.
