The pc worked great, i think there was a power outage, it probably affected somethingfull system spec? include make and model of the psu
new build or was working system?
the truth is, my computer is pretty clean, its just a buildup of dust in the cornersDear Sir/Madam: Please clean out your PC. That dust buildup(is that fur?) is terrible.
I wouldn't be surprised if your cpu cooler, case fans, gpu, and psu were all clogged with dust.
Get some compressed air cans - which you'll use on the gpu, psu, and cpu cooler, grab a lint-free hand towel, take the PC outside and clean it.
