Question System collapse ?

[Alejandro_]

Hello, Im using a translator because the english is not my native language

I had my PC for about 3 years and over time I've upgraded some parts. It started with an A320 motherboard, now its a B450. I used to have 16GB of Kingston 3200MHz RAM, now is Corsair 16GB 3600MHz. Same with the PSU always trying to go for slightly better. At this point idk what is causing the issue.

I use my PC for gaming. I play for a few hours then maybe take a break to watch a video or do something else. But when I go back to playing or sometimes even while I'm playing, the PC completely freezes screen goes black and it stops responding. RGB lights on the RAM, fans, keyboard, and mouse stay on, but if I unplug and replug the keyboard or mouse, they don't light up again, like theres no power going to the USB ports and obviously they don't work. To fix it is forcing shutdown. Windows doesn't show any errors in the event viewer so I have no idea what to do for fix that.

Also I wanna mention that once or twice when I turned on the PC it powered up but didn't show the BIOS logo just a black screen like with the other issue. I had to power it off and on again and then it would show the BIOS logo and boot normally.

Specs
Windows 11 Pro
MOBO Gigabyte b450 ds3h v2 BIOS F66
CPU Ryzen 5 5600g
GPU GTX 1650 ddr6
RAM Corsair 2x8GB ddr4 3600mhz
2X A400 Kingston SSD 480GB
Psu Corsair CX650m
AVR Koblenz RS-1410, 1410 VA / 700 Watts. I dont think thats the issue cause I know someone running a 4070ti and a 5600x with this same avr

¿What I tried?

Windows format multiple times but same thing.
I checked connections.
Did a general cleaning of PC.
Right now I'm testing it without undervolt. I do undervolt for keep CPU clocks more stable not for temps.

Did you reinstall the OS when you migrated platforms?

The latest is version F67g. make sure you're on the latest chipset drivers, then flash the BIOS to the latest version and then clear the CMOS.

Is this the green labelled unit or the grey labelled unit?

Windows format multiple times but same thing.
Did you recreate your bootable USB installer to rule out any corruption? Did you install the OS in offline mode?

How are you cooling the processor? Make and model of your case? Ambient room air temps?

I used to have 16GB of Kingston 3200MHz RAM, now is Corsair 16GB 3600MHz.

The maximum official speed for RAM on the 5600G is DDR4-3200. Your CPU will probably support faster RAM, but there's no guarantee if will be I00% stable at 3600MT/s.

If your BIOS is set to XMP/EXPO/DOCP 3600, try reducing the speed to 3400, or even back to 3200.

Run a full pass of MemTest86 at each XMP speed (takes several hours). If you get even one error, your RAM is not stable.

I have an old 2600X and it will not run faster than its official DDR4-2933 speed, without manual tweaks in the BIOS.

With DDR4-3000 RAM, I relaxed the CL(CAS) timings from CL=16 to CL=18 and it now runs at 3000MT/s.

The latest is version F67g. make sure you're on the latest chipset drivers, then flash the BIOS to the latest version and then clear the CMOS. Yeah I know but I had issues with F67b so I decided not to update until the stable F67 comes out. My chipset driver is updated.

Is this the green labelled unit or the grey labelled unit? No, is this.

Windows format multiple times but same thing.
Did you recreate your bootable USB installer to rule out any corruption? Did you install the OS in offline mode? Yes I do that but with conection

I do undervolt for keep CPU clocks more stable not for temps.
How are you cooling the processor? Make and model of your case? Ambient room air temps? My case is a XPG Valor AIR 6 fans and my cooler is a AK500 Digital I never have problem with temps

I do stress CPU tests with Prime95 no problems including the RAM and its never caused the error. My XMP is set to Profile 1 at 3600MHz I could try at 3200 but I wanna go one step at a time. I think not 100% sure this issue started after I installed my new GPU before that I was using integrated graphics. Yesterday I got an error in a game and the event viewer showed something related to nvidia drivers but I don’t think its a driver thing cause I reinstalled Windows a few days ago and like I said earlier I already checked all the cables and connections even made sure the GPU was properly connected

I have notices the problem appears again right now. it happens more with WWE 2k24 when I prees play (on steam) in the main loading screen freeze and black screen my pc. This was with undervolt off. I unplugged my keyboard and mouse but weirdly Windows come back and event viewer didnt even show any ID

I believe MemTest86 is a more thorough test of RAM than Prime95.

MemTest uses a set of worst case bit patterns including Row Hammer:

I wanna go one step at a time

You are currently running DDR4-3600, which is 400MT/s faster than the guaranteed maximum for the 5600G.

AMD CPUs can be more fussy about high speed memory overclocks than similar Intel CPUs.

I receommend changing the XMP overclock back to 3200MT/s or fit the old DDR4-3200 RAM, then run a full test with MemTest86.

If the memory passes MemTest86 with zero errors, increase the memory speed and run MemTest86 again (full test).

If you get even one error in MemTest, reduce the XMP speed or relax the memory timings (increase CL value) until MemTest86 passes all tests.

I do undervolt for keep CPU clocks more stable not for temps.

I don't understand how undervolting keeps CPU clocks more stable. Under normal circumstances the CPU clock rate changes widely between a very low value, e.g. 800MHz (idle) and a very high value, e.g. 4400MHz (single core boost).

Undervolting can make a system unstable if you go too far. I'd be inclined to run a long stress test (at least 8 hours) to check undervolt stability. Some people might even run a 24 hours stress test.

If you still have instability after getting a 100% pass with MemTest86, switch off the undervolt and test again.

Any adjustments you make outside the default BIOS settings can cause instability. I'd expect greatest stability with no XMP (2400MT/s RAM speed) and no CPU undervolt, using the BIOS defaults.

If you screw the waste gate (pop off valve) shut on a turbo and apply maximum revs, the engine might go bang. Stock settings are there for a reason.

Until you sort out the problems with the new GPU, switch off XMP and under volt.

Windows come back and event viewer didnt even show any ID

When Windows crashes and the computer switches off suddenly, you may not see anything in Event Viewer System logs apart from "Unexpected Shutdown". Not really much help.

Thx for reply

Today I did memTest for test my RAM sticks one by one in the same slot both 100% passed no erros at 3600mhz.

Undervolting helps my CPU stay at 4.4GHz turbo more consistently without it drops to 4.2 or 4.3 thats the reason I undervolt.

I recent contact with nvidia about this problem Im gonna wait

 

[Misgar]

if I unplug and replug the keyboard or mouse, they don't light up again, like theres no power going to the USB ports

A couple of things you could try:
https://www.supportyourtech.com/tec...-settings-in-windows-11-a-step-by-step-guide/
https://www.elevenforum.com/t/enable-or-disable-usb-selective-suspend-in-windows-11.10251/

The idea is to stop Windows from temporarily switching off USB ports to save power.

i know both sticks of RAM pass MemTest86 on their own at 3600MT/s (presumably for a full run?) but it might be worth disabling undervolting and switching off XMP too, so the CPU and RAM run at stock settings.

Performance will take a big hit in games, but if all the problems disappear, you'll know the system is good without any overclocking or undervolting, both of which could introduce instability.

the event viewer showed something related to nvidia drivers but I don’t think its a driver thing

NVidia frequently updates its Gaming drivers when compatibility problems are found with new games. Are you running the very latest driver downloaded from the NVidia web site? I use the NVidia Studio drivers which are more stable, but they might not work with your games.
