PC Shutting Down

[xenom0rphe]

Hey, my PC is Shutting Down when i play Microsoft Flight Simulator 2020 and after that i can't boot my PC until press the PSU's off then on switch. I did OCCT PSU test and after 17 mins of test PC shuts down again. Is this a PSU failure or overheating i don't know but what i know is my GPU and CPU temps are okay when i playing games. GPU temp is around 55-60 and CPU around 60-70. Don't know what to do. Another weird thing is PC is not shutting down when i play PUBG. It's only in Flight Simulator. Maybe its coincidence.

Sorry for bad English.

GPU: ROG Strix 2070 Super
CPU: R7 2700X with Stock cooler
Mobo: B450-F ROG Strix
PSU: FSP Hydro G 750W 80+ Gold
RAM: G.Skill Trident Z 3200 Mhz 2x8 GB

Sounds like your PSU is shutting down due to Over Current protection or one of it's other built in safety mechanisms.
Turning it off, then on again resets this.
This can also be caused by unclean power from the wall socket, a UPS (uninteruptable power supply) maintains a clean power supply to your system if required.

Another weird thing is this is not happening in night. I can play MSFS 2020 at night without any problems. Problem only in daytime maybe my home's energy is unstable during the daytime. Is this possible?

 

[bubbleawsome]

For sure possible. You could be having mini-brownouts during the day that trip up the PSU. Honestly though it could also be the warmer temps during the day increase the computer's power draw just enough to trip OCP.

My bet is power draw being the issue. MSFS2020 is probably the most demanding piece of software out right now, and will draw way more than PUBG will.

 

[FreedomEclipse]

Yeah... Asus has a history of of their boards being a bit sensitive with Over Current Protection on their boards. Its RNG if you get a board thats fussy about it or not. Some boards are fussy while some are not.

I run with OCP off though I am in part of my house that was recently built a few years ago and had fresh electrics installed and double checked afterwards by an independent electrician not affiliated with the group who did all the construction work.

Is your room air conditioned? If not, as bubbleawsome suggested, your ambient (room) temperatures may cool down enough at night to stop an overheating issue.

Daytime grid stability could be an issue too. So, as Caring1 noted, running with a "good" UPS with AVR (automatic voltage regulation) is a good idea. In fact, I always recommend all computers run through a "good" UPS with AVR, regardless how stable the power grid is.

Plus, every home and every computer user should have access to a AC Outlet Tester to ensure the wall outlet is properly wired and grounded to Earth ground. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets (outlets near water) too. These testers can be found for your type and voltage outlet, foreign or domestic, (like this one for the UK) at most home improvement stores, or even the electrical department at Wal-Mart. Use it to test all the outlets in the home and if a fault is shown, have it fixed by a qualified electrician.

In any case, since EVERYTHING inside your computer case relies on good, clean, stable power, you need to swap in a spare PSU and see what happens.

Thanks for the answers. I contacted to my electric supplier they will send a technician and inspect the issue. If there is no problem with my voltages, i will send my PSU to RMA. My room is not air conditioned btw. Outside temp is right now 35 degrees Celsius. At night its dropping around 28

Okay, but outside temp doesn't tell us anything - except it is hot out right now (35°C = 95°F). But you are not operating your computer outside, right? So what are your indoor temps?

The Laws of Physics dictate we cannot cool an inanimate object cooler than the ambient temperature with "passive" cooling. Passive cooling, in this scenario, includes fans and even water cooling that depends on radiators and fans. Only "active" cooling that uses some form of refrigeration, Peltier, evaporation, etc. will cool the device cooler than the ambient temps.

If your problems go away in the cool of the night, I think that is your answer.

Tried on another outlet and after starting PUBG, Flight Sim 2020, PC immediately rebooting. PSU is the problem for sure. Contacted FSP for RMA.

Other outlet proves nothing - especially if on the same circuit. If the other outlet is in the same room, it probably is on the same circuit.

PSU is the problem for sure.

For sure? No way! It certainly could be the PSU but it could be RAM, the motherboard, graphics solution, drivers, or facility power.

Right now im using Nvidia Driver 442.59 and Windows 1909. I will update to Windows 2004 and latest NV Driver. Gonna try this then.

Another room outlet not my room and Apartment inspected by technician. It's around 225-230V so there is no problem with that.

Mobo: B450-F ROG Strix

There's another prime suspect for you.
That board is gamer hype brand scam garbage and its CPU VRM is good only for 65W TDP CPUs.
It's literally worser than lowly Asrock B450 Pro4...
Which at least has three mediocre phases instead of four cripples...
And working VRM cooling instead of marketing having sabotaged cooling by crapping plastic excrement on top of heatsink.

In testing done by "The Stilt" stock 2700X doing x264 encoding overheated B450-F's VRM in 12 minutes and obviously Prime did same.
Even six core 2600X was too much load with PBO enabled.

And now you have there:

- Very high outside temps and no doubt elevated room temps even if having some AC​

- Non-blower graphics card dumping 200+ W of heat into case.​

- And are running modern day Crysis for CPU load.​

Certainly if it isn't the cause VRM must be running extremely hot.

I know my Mobo's VRMs are garbage but i look my VRM temps on HWInfo and OCCT when %100 heavy load. There is no problem with Temps.

While playing game these VRM temps are going around 60-70. I set -0.100 negative offset to my CPU btw.

My +12V rail is too low and CPU Power Reporting Deviation is Red. So that's telling me the PSU is dead. Even in BIOS +12V showing red around 10.5-11.00
