When browsing, using apps, listening to music, etc. all goes well but during gaming, although not consistent, it always hard freezes and goes black. I checked HDD CHKDSK and found no bad sectors and transferred PUBG(The game I frequent) to my SSD but still hard freezes.
I play GTA V, Sims 4, etc. They all hard freeze but not as worse as PUBG(Sometimes hard freezes when just pressing start). I don't know what the problem is. I clean installed my OS and installed all updated drivers but hard freezes still occur. The only lead I have was using Sapphire TRIXX and upping my GPU voltage to +38mV where in the default on startup is +13mV. When I upped the Voltage I played straight without any hard freeze it and lasted about 2 days before hard freezing again. Now I tried undervolting it and it hard froze like when I'm playing the game.

Update: GPU becoming more suspicious. Plugged HDMI to motherboard and the hard freeze occurred but no more black screen.

2nd Update: A day has passed. Did a memtest and found 2 errors. Hope desperately getting low. Will further investigate.

Played for an hour or two with CPU and GPU both below 70 but still hard froze. Now I really don't know where the problem is.
