Question PC suddenly runs slow after a short while

OK the only way I can explain what's happening is after a short while of the PC being on( the actual time frame is random could be an hour could be straight away or anywhere in between) the whole computer seems to lag but instead of things taking a while to happen it's just jumpy and game will drop from 60fps to 20-40 and be all jumpy likes it's skipping frames. YouTube videos start jumping and the audio goes all choppy and cracked.

The only way to get it back is a reboot but then it happens again. I've tried swapping the gpu with the wife's and vice versa to the same effect, removed the audio card I had in case it was some interference but no luck, moved to a new location in the house for the same reason but again no luck and finally I've swapped psus incase it's a power issue and again same deal.

I've had cpuz, open hardware monitor and core temps running all of which show temps of 40-60 so no thermal throttling and the fans are running fine. My only remaining option is cpu and that's quite hard for me to just swap out.

Anything anyone could help with?

Running rx580 and ryzen 2600 with 16 ram.
 
Slowing down after a time is usually a symptom of a heat issue and throttling.
Run HWmonitor. It will record the current, minimum and maximum temperatures.
A high minimum indicated a cooler mount issue.
A high max indicates throttling.

Try running with the case doors off and direct a fan at the innards.
If things get better, look to case and cpu cooling solutions.

Sounds like symptoms of high temps/throttling, but you say they're fine. What's your motherboard, power supply, CPU cooler, etc?
I'm using the stock cooler that came with the 2600. The motherboard is a gigabyte x570 aorus ultra gaming cf. The power supply is a be quite 800w or something along them lines and I swapped it out for some 1200w thing I borrowed from work which I no long have at home since it made no difference.

I've since swapped the ram and tried different slots to no avail. I've rebuild it from scratch with just the basic parts and using new thermal paste but still the same.

Coretemp goes upto a max of 48c with 32w average power draw. Open hardware monitor shows the gpu at 65c max with a max power draw of 106w.

I popped a 3700x in but it wouldn't boot so I assume it's not compatible as it works on another rig.

Also I've had the case open all the time whilst testing and tried with a desk fan so help cooling but made no difference.

Any ideas?
 
What is your bios level?
CPU-Z will tell you.
Current is F30:

3700X should be compatible, even with the initial F3 bios.

ryzen seems to be very finicky.
Particularly with ram.

Run memtest86.
It boots from a usb stick and does not use windows.
You can download the free edition here:

If you can run a full pass with NO errors, your ram should be ok.

Run a simple stress test using the bench tab of cpu-Z.
That will remove causes such as graphics, game, and windows issues.

Stress test the graphics card. I have no expertise there.

Once you have eliminated hardware issues, then you can go after the more difficult to find software issues.

Why an X570 board with a 2600? The 3700X is compatible with all B550 and X570 boards, so there may be an issue with the mobo of some sort. 65W should be where it sits at full load.
