Question help, screen making weird pixel things sometimes

[loismke]

so i have made my own desktop about 2-3 months ago
amd radeon 5700xt
amd ryzen 5 3600x
asus x570 a pro motherboard
16gb ram
with windows 10

but since a week ago when i was just random watching youtube i got some weird purple squares in my screen (picture attached) and it maybe stays for a few seconds and then goes away it has happened a few times since then. not sure if this is a software or hardware issue.
