Question PC freezes when idle ?

[livialivialivia]

Hi, I have an AORUS x570 Elite mobo with 4 sticks of ram. Out of the blue, my PC started freezing , especially when idle. I tried removing 2 of the sticks to see what would happen. The freezing got less frequent, but still happened. I swap those 2 sticks for the other 2 sticks. Same. Then I tried with 1 stick of ram. The freezing got even rarer, but still happened. I switched the 1 stick for another one (of the 4). Still happened. Then I found out about a setting in the bios called Power Supply Idle Control. It was on auto, I switched it to Typical Current Idle. Freezing was gone . I got lazy and didn't put the other RAM sticks in for months. Things were still working great. Now that I've put them all back in, the problem is happening again.

I am suspicious it's not the RAM sticks because of how it still happened with the 1 stick until I changed a PSU related setting. Also I had run a memtest previously with no errors. So probably the PSU? Probably changing the current setting made it more stable, but it is not stable enough to run 4 sticks of RAM in sync. Other possibility is something with the MOBO. Maybe a BIOS flash? (afraid of those) Or could really be the RAM in the end.

I wanted some pointers as to what to try to tackle first since I have very little spare time to diagnose this, and it might require buying new hardware to test it out.

thanks in advance

I recently had the same issue with windows 11. what's your full pc setup and what operating system you running?

GYGABYTE Aorus x570 Elite Wifi
Ryzen 5950x
RTX 3090 (tried with a 3080 ti and had the same issues)
Swapped my nvme for a new one, still same issue
Corsair RM850x PSU

OS was windows 11, formated to win 10, same issue, now back to win 11 again.

Do you install any software after you do clean os install?

if it freezes on a clean os install without any additional software/programs it could be your ram, you could try a memtest, otherwise check windows event logs to see what happened before your pc froze. and are you using any external drives?

Thanks for the tips. It seems I have solved the issue, and I'll register it here for anyone having the same problem. In the BIOS, under Power and Performance Options ---> C-State Efficiency Mode set that to disabled. From the information I've gathered, the fact that I need to disable this for my PC to stay idle without issues might point to the CPU being the culprit since this is a CPU-related setting. I also suspect it might be because I am not on a stable version of the BIOS. Either way, this has solved the issue for now, and I will try a BIOS update in the future just in case.
