Also i bought the parts about 8 months agoMy guess would be a thermal issue with the GPU. What temps is it running at?
Ya i use msi afterburner burner i use that osd thing that some me the temp and performance while i am gamingThe thermals won't become an issue until around 85-90. Crash typically happens at 90+. A 750 watt psu should be more than adequate for anything in the 3000 series, with a maybe on the 3090. Your PSU is pretty decent with solid reviews so nothing blatant there.
Are you watching the thermals with the normal clocks set in afterburner while playing the game?
I did think it was my gpu but i ran a few test and it passed i also tested my ram sticks individually and also ran a test on my ssd all passed so i am thinking the psu might be faultyYa i use msi afterburner burner i use that osd thing that some me the temp and performance while i am gaming
