got a few questions:
Do you use ATI catalyst control centre or any of ati graphic card or something?
if yes this is the problem
here's the fix that worked for me ^^
1.download and install the latest ati graphic driver.
go to C
Windows\System32\Drivers
rename atikmdag.sys to atikmdag.sys.old.
Go to ati directory ( default is c
ati)
find atikmdag.sy_
copy it to desktop(for better handling
open cmd and write chdir Desktop (to change the path)
type EXPAND.EXE atikmdag.sy_ atikmdag.sys. Or,
expand -r atikmdag.sy_ atikmdag.sys
when its done copy the new atikmdag.sys from your Desktop to C
Windows\System32\Drivers
restart and bam! it should get solved
thge problem is in amd ati ccc
if the porlbem continues do not install catalyst but update it ffrom device manger
