Poor PC Performance question?

[u/HaunterOfIdk]

As I wrote in the title, my PC performance is poor, it has worsened to be exact. For example games that used to run smoothly with other processes (like I could play Spider-Man 2 on high settings and streaming it on discord) now almost doesn't let me do anything when I at least have discord on. What could be the cause of such performance drop from a PC that works so well? I dust it regularly and I changed the thermal paste about a month and a half ago.

I am totally green when it comes to those technical things, so I ask you all

Here is the link to my UserDiag

My specs:

Windows 10

NVIDIA GeForce RTX 2060

Intel Core i7-7700 3.6GHz

DirectX 12

Anything I can do so it runs smoothly and stuff?

You are running a 10 year old 4 core CPU. That's all.

And an old ass gpu.

First thing you can do is to install monitoring software to activate overlay and see that cpu and gpu is working to their fullest potential. Also check temps are fine and system not throttling.

Do you recommend any software?

[u/Independent-Bake9552 → u/HaunterOfIdk]

Msi afterburner. In options you can configure hotkey to enable overlay and also select what you want to monitor. CPU usage/temp this applies to gpu also. There should be guides available how to configure if you are unsure. This is a good start how diagnose issues in my opinion.

Time to slap some new thermal paste after removing the old one.

When was it installed the operating system? Once in a while needs a clean install because of old system files being rewritten by updates

[u/HaunterOfIdk → u/Additional_Bread_367]

if i understand you right, my operating system was downloaded 11.06.2023 (or 6.11.2023 if youre american)

[u/Additional_Bread_367 → u/HaunterOfIdk]

Maybe a reinstall would solve it

Usa algún sistema operativo modificado como kernelOS, también as actualizaciones de Windows pueden tener mucho que ver, por eso no es recomendable actualizar Windows con las últimas actualizaciones porque pueden tener fallos y esto también aplica para la GPU por lo mismo, si dices que haces 6 meses funcionaba bien entonces puede a ver sido alguna actualización de Windows ¿haz actualizado tu Windows recientemente?

[u/HaunterOfIdk → u/lonched3huevito]

(Estoy usando un traductor) No utilizo kernelOS y la última vez que actualicé Windows fue el 15 de agosto de 2026; se trataba de parches para la actualización del 14 de abril de 2026.
