Low resolution and Thread Stuck In Device Driver

Question asked by atti on Dec 1, 2015

I have 2 problems with my Radeon-card (MSI Radeon R9 290x) and both happen randomly.


1: ~Once a month after computer wakes up from hibernation and gets to login screen resolution is 800*600 and resolution can't be changed and after unplugging and plugging mini-displayport cable resolution gets restored to what its supposed to be (1920*1200).


2: Somewhat weekly waking up from hibernartion restart gets interrupted by BSOD thread stuck in device driver exception (0x000000EA) and cause is atikmdag.sys (file path: C:\Windows\system32\drivers\atikmdag.sys) and I've uninstalled and reinstalled drivers several times and last time before Crimson-drivers I even used Ati uninstaller and re-installed drivers w/o help (and Crimson didn't fix it either).


All drivers and BIOS are uptodate.
