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.

Hello

Colored squares usually means the card is failing. Do you get the odd colors during the boot sequence?

[loismke]

no, they only come while gaming or watching youtube they come and dissapear again, and the weird thing is when i take a screebshot they are on the screenshot too

I concur with veeg, hardware is failing.
you could remove the GPU, wipe it down with a brush and wipe the contacts both on the card and in the mobo slot.
reseat it and see how that goes.

if it only happened during YouTube, I would suggest upgrading your browser to the latest version or even trying another browser to verify that fact.
but since you say it’s also durng games, that would suggest a faulty graphics card to me.
