Performance issues on new PC

New to pc gaming after buying 1st pc around a month ago. Just looking advice on what could be causing the issues I’m having.

For the last week, I have had trouble when playing MW2. It first started stuttering constantly when playing and then began to crash when in matches. I tried verifying files on steam and it would show that 38 files weren’t recoverable each time. So then I deleted some of the files under the properties section and reinstalled the game as well but neither helped. Then the game showed white horizontal lines that would flash around the screen. Thought it might have been the display cables connection to monitor so checked it wasn’t loose but no effect.

Not very technical so looked up online and it suggested checking drivers, windows etc. the drivers were updated to latest version and I done a clean install. Everything else also seems to be updated as well.

Then the flashing lines returned so I quit the game but noted it was still on the desktop. (It also recently happened and I loaded up cyberpunk and still remained). Went into task manager and from what I recall the lines were gone.

Today they returned and I switched the port the display cable was connected to on the gpu and it stopped it, at least for now. The stutters happen when my FPS drops from around 170 to 130-40 suddenly. I’m running the game at max settings as well. I didn’t notice the issue a few weeks ago. When I play cyberpunk only I don’t have issues. Dead space I get stutters but heard it’s common.

The specs are:
CORSAIR iCUE 5000T RGB MID TOWER GAMING CASE

What connections are you using between the display and GPU? If you're using HDMI, there are limitations that may make that refresh rate impossible.

There’s the back ports thanks. Also I tried verifying game files for mw2, cyberpunk and dead space on steam but only mw2 has files which aren’t recoverable if that means it’s caused by the game. Although is it normal for flickering to happen outside the game once it starts.

What GPU do you have? I don't see one mentioned in the specs?

You'll need to apply all those just to get windows up to date. I don't think it's a windows issue, but best practice is to have an up to date platform.

Regarding MW2 specifically, it does seem to be quite a common issue, came across this which may be worth checking out

"The solution to the stuttering problem is simple, as Maven states that simply raising the “Spot Cache” setting to “High” or “Ultra” in the graphics menu of MW2 and Warzone 2 will completely fix the stuttering."

Tried the above. The flickering still happened outside the game and in task manager so I switched to a hdmi cable and it seemed to go away. Now switched back to the display cable and it’s been fine for now

So returned the PC and it ended up being a gpu issue. It was switched and got it resent out on Tuesday. Since then I’ve still got artefacts appearing that become more unstable. Also a fan stopped working. The fps drops/stutters are gone at least. Took photos of the artefacts and the fan

Fan could be a loose cable? Take side panel off and check all the cables into the Commander Core are fully inserted with a firm push. See if that resolves it?

As for GPU, have you tried a clean uninstall of the GPU drivers using DDU, and then a clean install of the latest drivers?

Oh thank you the fans working now. I can’t enter safe mode on the pc. I have the ddu uninstaller on it but anytime I try to restart in safe mode it gets to here and restarts without giving option of safe mode. It just restarts before getting to that screen with the options 1-9

I don't think I've ever needed to be in safe mode for DDU.

What steps are you following to enter safe mode?
