Question Small GPU glitches after dusting

[Niekjes10]

Ever since my dad and I cleaned my pc I have had small glitches where sometimes a few pixels turn white for a short second and once in a while my entire screen turns black for a second. I tried updating my drivers and using a different hdmi cable but the issue still remains. It doesn’t look like the hdmi ports are damaged so I’m afraid it’s a problem with the GPU. For cleaning we used an air compressor which according to my dad filtered out water vapor. We didn’t let the fans spin too much during dusting. It wasn’t connected to anything including power while cleaning.

Specs
CPU: Ryzen 5 2600 wraith
GPU: MSI GeForce 2060 ventus 6gb oc
PSU: Corsair CX550M
Ram: 4 x 8gb Corsair Vengeance LPX DDR4 3000MHz C16 XMP 2.0

Does anyone know what might be causing it and how to fix it?

Thanks in advance

Id reset the card in the PCI slot.
(turn the PC off)
Vaccuming is good.
Pixelation usually means the GPU is on its way out.
I had a GTX 560 TI that I had to put in oven every year to get to work again... Research putting your GPU in the oven to resolder the pins.
