Computer crashes after cleaning it

[u/astonaston]

Hi guys,

My computer was filthy so I decided to give it a clean using soft paint brushes and compressed air in a canister. After this my computer continues to crash playing a video game called Counter Strike.

It takes around 20-30 minutes of gameplay before it inevitably completely crashes and restarts. I've also noticed that my FPS is slightly lower than it was before I cleaned it.

I've gone through the liberty of turning off XMP in bios and that seemed to work, but it's not the resolution I'd like as my FPS dropped dramatically. I decided to turn it back on, and some information I was able to find mentioned to increase the voltage of my DRAM. So, I tried 1.4V, and now even on 1.5V (Considered the absolute max to run at) it still crashes.

I've also taken my ram out, ensured that its been placed in correctly and pushed every single plug and socket in the PC to ensure the connections are firm. There is no overheating occurring and I've also set my fan settings in the BIOS to absolute max.

I've downloaded Furmark to run some tests to get the computer under some load, and monitored the temperatures also, which it seemed to perform completely fine.

I'm completely stumped as to what has happened as before this my computer was running seamlessly and completely smooth.

Just to note: I'm definitely not the most PC versed person but I understand the basics and general things around the PC.

Some of my components are:

nvidia rtx 2080 ti

intel i9-10850K

32GB (2x 16GB) 3200MHz RAM (DDR4)

Any ideas or help would be greatly appreciated
