What is Overheating?

[Setton]

I had my PC down in my basement next to my server rack that was pumping out way too much heat and I ignored it for too long (That's been sorted out). Point is I let my PC run in a room with a really high ambient temperature for too long to where it killed both my monitor and SSD (Those have also been fixed). But now my PC is in a normal room temperature area but something is still overheating. Under normal load everything runs fine with no issues but when running any high demand games it will occasionally hard stop. I've already insured that it's getting good air flow and reapplied thermal paste on the CPU. I've tried monitoring CPU temps and seems that at worst I'm hitting low 90 c so it can get a bit high but not overly high so I suspect that my problem is the PSU. My other clue is that when it hard stops I can't just turn it back on I have to flip the PSU power switch off/on first. I'm not sure if that's a feature added with new PSUs when a system over heats or if it's a clear indicator of the power supply going out?

My current build for details:

TLDR:
Does having to flip the power switch on the power supply after a hard stop crash mean the power supply is going bad?

i think there are different issues here

1) cpu overheating... get a better cooler make sure its installed properly 

 

2) psu. get a better* one

i mean, yes, that's highly likely and pretty weird at least. 

 

*not to say thats a bad model, but it may be broken or simply doesn't cut it for this system

Seems to me an overheat issue

There's safeguards so that you can't reboot for a time on overheat shutdown

psus have a future called over current protection also in the motherboard there is a future incase of voltage breakdown to under a specific voltage its gonna stop working to ensure to not get harmed there are two posibilities base on my understanding of electronic and what you said, one is the problem is with psu and it cant provide enough current so the voltage breaks down to a point motherboard fale safe get triggered, other posibility is there is something wrong with motherboard and there is a very small short in the circuit and in normal use this short is small enough to not exceed current protection of the psu but in heavy loads it exceeds that and power supply triggers the over current protection, if you have a multimeter around try to connect the black prob to any black wire of the psu and red prob to a yellow wire and put the multimeter in voltage mode and start any high demand work and while monitoring multimeter if the voltage first dropes then it get shot of most likely can be a broken psu, if you have any other psu around try that one to see is it working properly or not, also you can unplug all unnecessary things like hdds and anything you can do your heavy load without except your cpu pomp and fan and try it again there is a posibility the electrolitic capacitors defected over time in past two years by thhe heat and they got weaker so psu now cant provide enough power for heavy works,  just do not try to open the psu in any situation it is very very dangerous do not open the psu for any reason and do not touch any wire even inside the pc and be really carefull while connecting multimeter prob act like you are working with ac, and dont forget to ue a ground wire to connect yourself to ground if you needed any more explanation on testing please let me know

Heh, guess if it's broken then a new one would be better, initially I was planning on getting an 850w can't remember why I wound up with 750w was probably due to miners taking all the bigger ones at the time. I had the older version of the H100I AIO in my last build and that's still going strong so figured the new version would work for my new PC. I know I can get better cooling out of those nice Noctua's but I really like less bulkiness of water cooling and can't be bothered with doing my own loop. I'll have to research it a bit more.

Saving a bit of money isn't worth risking death (even if it's a minor risk), same reason I stayed out of the old CRTs back in the day. 

I'll probably start with my initial thoughts and get a new PSU and maybe AIO. If those doesn't work then well guess I'll just start swapping things until I find it. My son is due for an upgrade so he can take what ever isn't broken. 

 

Thanks for everyone's replies.

Just as a follow up to this, I think I sorted out my issues but ended up taking the shotgun approach so not 100% sure what resolved it. Wound up getting both a larger AIO radiator and a new 1200 watt 80+ plat PSU (was going to get 1000 watt but the larger one was cheaper due to discounts). I also repositioned my AIO to front air intake and am getting much better temps under load. At some point I'll test out my old PSU in another system and see if it acts up but at least my primary is running stable now.

hi any news on testing old psu to make sure were was the problem?
