hello, i have a pc which i built a year ago. I've always had minor issues with he GPU but I've always managed to fix them. but recently i was playing beamng.drive, i got some hiccups so i checked the stats of my gpu and everything was looking normal. then my screen froze for about 10 seconds. then everything came back, but i did get a GPU is not responding error. a couple seconds after i closed that message my pc crashed. when i tried to reboot it didn't give any signal. after a couple of reboots it did come back but this has happened 5 times for the last week. what could've caused this?
specs: 3200mhz corsair vengeance 16gb ram kit (2 sticks)
ryzen 7 2700x
4gb gtx 980 (pny)
asrock b450m pro4
edit: i was playing minecraft recently and i had about 10 micro stutters per second
