Question Who able to help me with PC diagnose? I have overall weird performance.

Well, For the first i have these specs:

GPU - RTX 2070 Super EVGA
CPU - Ryzen 5 5600
MB - Msi B450m pro vdh max
RAM - 32GB 3200mhz 16-18-18-18-36
PSU - PCCooler GI-K800 (Basically 800 watt 80+ gold)

I have issue with sudden stuttering, lagging, bad screen recording performance.

None of components experiencing overheating or throttling. And none are causing bottleneck. (none is overloaded to 100%).

I have scanned my PC with antiviruses hella lot of times, no clues. (also tried installing pure windows on other drive, still freezing)
Any ideas? Drivers? Viruses? Faulty GPU or CPU?
 
Welcome to the forums, newcomer!

What BIOS version are you on for your motherboard?

PSU - PCCooler GI-K800 (Basically 800 watt 80+ gold)
Low end(quality) PSU regardless of the wattage. How old is the PSU?

What OS are you working with? Make and model of your monitor and the resolution you're running/gaming at? You also forgot to mention the make and model of your storage.

None of components experiencing overheating or throttling. And none are causing bottleneck. (none is overloaded to 100%).
Make and model of your case? How are you cooling the processor?

Drivers?
What driver version are you on for your RTX2070 Super?

Viruses?
Run malwarebytes and see if something comes up.

Moved thread from Components section to Systems section.

Had to check Bios ver though

Bios Ver: E7A38AMS.BM0
Bios Build Date: 07/25/2024

Windows 10 OS.
Monitor I don't know aswell, just some vega 1080p 75hz thing.
Basically latest i could get from geforce experience (ain't going to nvidia app)

I told I scanned for viruses with different software aswell. After this reply I do once with malwarebytes to be sure.

About case and cpu cooling - the joke is better to be a image, but I can't upload it.

UPD:
PSU is around ~1.5-2 years in work, bought one Used.
Basically all of my storage is:

Seagate Barracuda ST4000DM004-2CV104 #1
Seagate Barracuda ST4000DM004-2CV104 #2
Toshiba HDWD110 #3
 
For screen recording you need to pull data from the graphics card over PCI express bus. It so happens this is rather slow. In your case, you have only PCIe-3.0, not sure how many lanes.

It is possible that some process fires up and loads up PCI express bus, which interferes with recording process. Possibilities include graphics apps like video game, video conferencing, graphics effects in the OS, and maybe even the new MS AI agent trying to take screenshots. Also check power saving settings - maybe something is trying to put the PCI express bus on power save.

I would start with finding out how much PCIexpress bandwidth you actually have available for reading and then trying to measure how much bandwidth your screen recording process needs when it is working normally.

Both Motherboard and GPU has PCI-E 3.0 x16, RTX 20 series are all Pci-e 3.0 x16 width.
 
This means that your theoretical read bandwidth is 16 GB/s. In the past many video cards had significantly slower memory read speed, not sure what the situation is now. To capture video at 1920x1024 at 75Hz 32bpp you need 0.5 GB/s. So if you could read at full speed it should not be a problem, but if you get significantly less you can be bumping into limitations.

What happens if you switch your monitor to lower refresh rate, say 30 Hz or 60 Hz ? I assume it is LCD, right ?
 
Take a closer look at how your system is performing/working by using Task Manager, Resource Monitor, and Process Explorer (Microsoft, free).

Use all three tools but only one tool at a time.

You will need to open the tool window and leave the tool window viewable.

Then game, work, etc. as usual while watching the tool window.

Look for what changes when stuttering and lagging occur.

May take a bit of trial and effort on your part to work out the process.

Objective simply being to discover what the system is doing, trying to do, or stops doing when the stuttering and lagging occur.

Take your time, be methodical, watch carefully.
