I googled for answers to this problem which I am assuming it is my video card and none seem to be working. I am running on a HD 4890. I know it is considered old for Windows 8 but I have been using it for a while with no problems using the legacy drivers. Since I've been getting this error I've cleaned it out of malware in safe mode and also reinstalled the drivers. The errors sometimes only occurs when i launch a game or I can't even get into windows. One difference I've noticed too my error is different than the other because it contains (atikmpag.sys) on it. Any suggestions or solutions? I really don't want to buy a new card because I don't have the money right now so maybe downgrade to Windows 7? Thanks for the help!
