I bought my new laptop around 1 week ago it came preloaded with windows 8 pro, but because it wasn't giving me gaming performance so i changed it to windows 7 after installing drivers t worked absolutely fine but after restarting it after 1 hour of shutdown it is showing various problems like:
none of the windows programs, my games , applications are working and getting the appcarsh error again and again.
. dwm.exe has stopped working.
. catalyst control panel has stopped working.
. and games.exe has stoped working errors.
please try solving my problem as soon as possible.
