Green dots appearing in games

[dark1g]

I have my pc about an year ago and it start appearing some green dots like a laser on my screen and I get freezes on pc even the voice is "lagged" when I have those. Also if I disable the v-sync the game is unplayable I start having "lag". And for example in GTA V I get a massive dot with pink flashes.

I send the pc for warranty and they said I had a conflict with drivers and sent me back for testing I came home and the problem is the same what can it be? My graphics card is an ASUS DUAL RX480..

I leave a print here on fortnite.

Try installing your windows clean. Install back ur drivers and games. Try them out, if problem still happens it's probably a faulty gpu or faulty monitor.

Those are graphic card artifact from overall card overheating mostly but not always from overclock, or due to poor case airflow with insidious individual graphic card components overheating (vrms), usually nothing that running the card at base settings, adjusting it's fan curve to spin at higher Rpm when gaming and improving the overall case airflow around the card wouldn't fix.

amilio:
They did all that things there..

ROGG:
I never done an overclock it's stock speeds.
About the airflow I have an Nox Hummer MC and they made me all the setup in the store..

So best advice send it back to the warranty?

If card still artifacting despite good airflow and the usual adjustments of it's cooling and conservative settings it is a definite candidate for an RMA.
