Weird Blackscreen whie Gaming

[Luvire]

Hey guys, I have this weird issue: When playing (mostly rainbow 6 siege), my screen turns black sounds goes on, and then it comes back after some seconds. no crash shwoing in eventlog, nothing showing donw on the task thing of windows (sorry im German, forgot how its called in English ^^) I think it may be a faulty HDMI cable/connector, but I dunno....

Intel Xeon e3 1231 v3
Hd 7850 (1165mhz 1350 memory 1155mv)
550 aurum cm
ga h97 d3h
850 pro ssd
1 tb hdd


Any help is appreciated!

EDIT: CHanged to DVI, had it again. It also seems like i only get this once per boot...very strange

Hi,

Usually this happens when

1- cpu=gpu overheating : download msi afterburner and hwmonitor to check you temps
2- weak or bad PSU: test with a known working psu
3- bad GPU driver : try newest or older driver version.

Good luck

cpu and gpu temps are in bounds, i dont know about psu, never had accidential shutdowns or anything and the problem has been persistent throughout 3 drivers :/ also, i found out that it doesnt only happen once a boot, so i dont think its a programm popping up. if only recognized this problem since win 10, i dunno...i have no spare psu to test sadly
