Any updates?
I had to bring mine to HP Service Center, got the board replaced and the issues persist, i dont know whether i have bad luck to have two defected board or it's design flaw, i know some people have the same issue with RX6600M whether it's on HP or MSI, they all have the same issue with the exact same discreet GPU chips, either it's a driver issue in which they can fix with decent updates or it's the chip issue which we can't do anything about it.
I hope some people manage to get refund out of this.
