Question Regular graphical glitches (Unstable artifacts?)

[BLEACHED]

I have no idea which part of my build is giving me these graphical glitches... I've read online that when purple/green appears it's an indicator of a bad GPU...? My exhaust case fan on the back is spoilt so I manually spin it with a stick everytime I boot up my PC (thankfully it continues spinning after that) so could it be a case of GPU being thermally throttled? Here are some screenshots for reference. Since I bought my pre-built system from a vendor I can't RMA my GPU directly from the manufacturer, and my 3-year warranty with the vendor has expired.

CPU: Intel i5-8400
Cooler: Intel stock air cooler
MOBO: ASRock Z370M Pro4
GPU: Nvidia Geforce GTX 1060 6GB
RAM: 1 x 8GB ADATA 2400 mhz
SSD: 120GB KLEVV NEO N600 M.2
HDD: 1TB Toshiba DT01ACA100
PSU: EVGA 450w Bronze+
OS: Windows 10 64-bit
BIOS: P1.40

Welcome to the forums, newcomer!

First off, you have BIOS updates pending. I'd work through in this order; 1.7>1.9>2.0>3.1>3.2>3.3>4.0>4.1>4.2...yes you have a lot of BIOS updates pending. Don't jump to the latest BISO version, since that often results in a bricked motherboard. EVGA is the brand of the unit while 450W is the advertised wattage, what model is the unit? As for the PSU, how old is the unit?

Use GPU-Z to see what the memory on the GPU is showing.
