Over the last two days, whenever I try to play games on my PC, the monitors lose connection, but sounds like Discord calls and game audio are still there. I opened it up to find that the GPU was full of dust. Wondering if anyone could help me! Also, when I run the MSI stress test, the same thing happens.
Game: Fortnite
CPU : I7 7700k
GPU : Nvidia GTX 1070
16 Gigs of DDR4 RAM (IDK what type)
Air cooler (IDK what type)
IDK what the rest of the parts are.

clean the gpu, check the temp
what the make and model of the psu?
Don’t exactly know what type. I looked at the sticker on the side of the PSU and just saw a jumble of Chinese, english, and Spanish. It came stock with my omen but I don’t know the exact specs. Just blew everything out and i’m about to try again!
