Question Help me troubleshoot system lockup

[dmcguckin]

Hey all - trying to troubleshoot here, my system has been locking up randomly the last month or so. Will be random times, could be gaming, could be web browsing. Hard lockup, screen will just freeze on whatever is going on at the time, no sound, have to turn off PSU and turn back on. No system logs or events related to it. Was stable for months before this. Turned off PBO - still persists - just turned off DOCP in Bios now, will see if it still happens. Any thoughts? I have rolled back GPU drivers, installed new GPU drivers. Windows updates etc.This is not temp related (I believe), system is water cooled.5950x, Dark Hero mobo, EVGA 3090 - all on water.
Windows 10

Specs:
CPU:5950x
MB: Asus Rog Crosshair Dark Hero
PSU: Evga 1000 P2
GPU: EVGA RTX 3090 XC3 Ultra
RAM: 64GB Crucial (2x32) - Ballistix 3600

"No system logs or events related to it " - meaning no errors, warnings, or even informational entries in Reliability History or Event Viewer. Correct?

How old is that 1000w PSU? History of heavy use for gaming, video editing, or even bit-mining?

= = = =

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, and jumpers are fully and firmly in place.

Check for loose screws anywhere. All screws should be carefully snugged down but do not overtighten.

Use a bright flashlight to look for signs of damage: bare conductor showing, melted wire insulation, kinked or pinched wires, browned or blackened areas or components. Swollen components.

Also remember to check the applicable power connections from outlet to system. There should be no wiggle or give in any applicable outlets and plugs. Temporarily bypass power strips, UPS, etc. to determine if the problem stops. Include all peripheral devices: audio, video, storage.

The PSU is several years old 11/2018.
I am a video editor so yes I render with it. - correct, nothing in the event viewer except for the system shut down incorrectly log.

System is very clean

For the moment I will lean towards a PSU problem.

Three years old may be approaching the designed in EOL (End of Life) for the PSU. All the more so if steadily used at high wattage values for rendering, gaming, bit-mining etc..

PSUs provide 3, 5, and 12 volts to varying system components. It only takes a minor glitch or outage in any given voltage to cause problems.

I.e., an incorrect shutdown.

Is it possible for you to borrow another known working PSU to swap into your build?

You can also do some limited PSU testing if you have a multi-meter and know how to use it. Or know someone who does.

Not a full test because the PSU is not under load. However, any voltage out of tolerance makes the PSU a primary suspect.

I was thinking PSU as well, however it is a good PSU with a 10 year warranty on it. I'm going to run Memtest all night tonight and see if that shows any errors to rule that out.

8 hours of memtest last night gave me no errors - so I'm thinking RAM is fine.
