I had all my system conected to APC BACK UPS 750W and then I decided to buy new videocard. I used DDU and changed in my whole system only videocard from msi r9 380 4g to Gigabyte rx 5600 xt gaming oc 6g (f60-f61) and my nightmares have started . Now sometimes I`m having random reboots. They happends in random situations and I think never in stress tests or smnth like this.Tried do stress test and all good, tried . /sfc scannow no erors, memtest = good , OCCCT all types - all good. Have fulltower case and never have temperature trobules.
