Hard crash

[DredKn0t]

 Hello all,

   So I have been having this issue since I built my new rig about a year ago now and it's only getting worse. My issue is that my PC will just crash at random times. By crashing I mean it suddenly shuts down, monitors go black, RGB on the motherboard, GPU, CPU and Ram all turn off for about a second. Then the RGB comes back on like it's going to reboot and it doesn't. I can see the motherboards post codes and it doesn't show anything out of the norm. PC will not start back up until i turn the PSU switch off hold the power button to drain anything left in the system, then flip the switch back on and press the power button again. I have run individual  and combined stress tests on the CPU, Ram and GPU and I am unable to reproduce this crash. It only happens when I'm playing games that are on the more demanding side. All my drivers and BIOS are up to date and all components are running at stock speeds. All temps stay in an acceptable range. I'm thinking it's either bad Ram or a bad PSU. Specs below. Thank you in advance for anyone who replies to this post.

 

Motherboard: Asus ROG Strix x570-E Gaming

CPU: Ryzen 3800x (stock wraith cooler)

Ram: G.Skill Trident Z 32GB (16x2) 3200 CL16 (running in dual channel mode per motherboard specs)

GPU: Asus ROG Strix 2070S

PSU: Corsair HX850i 80+plat. 

Case: NZXT H700

The behavior sounds more indicative of a bad PSU. I don't know about the RGB turning back on after it shuts down but if you have to hit the button on the back of the PSU to get it to power back on that sounds like over-current protection.

 

There's no way your system is pulling 850W+ which makes me wonder if there's an intermittent short somewhere that just makes contact under the right thermal conditions. Could be a bad cable, adapter, or an issue withe a component (drives, motherboard, GPU, etc.), could even be the motherboard shorting on the chassis from a unnecessary stand-off.

 

I'd probably start by both testing a different PSU and try running the system outside your chassis.

Got a new PSU and it solved the problem. Thanks for the tips!
