Hi,I need help
During a game I suddenly get dancing pixels all over my screen, after hours of workin around my findings are
-works completely fine in safe mode
-i need to disable the graphic driver (Intel Hd Family) for it to have a clear display but makes games unplayable (03 fps)
-updating drivers don't work
-no malware detected after tons of scans
-screen is completely clear before log in screen
-all scans says hardware is okay
-it isn't dead pixels
I have an Acer Aspire E15 with Intel Hd family and Nvidia GeForce 850M as graphic cards but disabling one makes the other unusable.
-dancing pixels is permanent unless in safe mode/disabled display adapter in device manager
Would love some help after hours of troubleshooting
