Please help my brothers pc ryzen 5 3600 16gb ram had a msi r9 390 he bought a Asus gtx 1070 as an upgrade I swapped the cards removed old drivers installed new ones and when gaming only tried player unknown battlegrounds so far it bsods to video tdr failure nvlddmkm.sys I thought maybe it could he left over files from the 390 so did a clean install of windows but still the same issue so I tried an older nvidia driver still same issue then I tried his 1070 in my pc I7 6700k 32gb ram and the card ran fine no problems I thought it could have been psu so swapped my evga 750w for his corsair 550w but this made no difference it still crashed on his cpu but not mine
