AMD catalyst centre gone and pc very very slow

Just logged onto my pc and its gone mental. Says my catalyst centre and graphic card I gone. Seems to have done some sort of update. Pc is also extremely slow and unresponsive. Writing this message has taken a good 10 minutes as the keyboard lags behind my typing.

The message that appears is in the attached picture. Can anyone help? was hoping to have a relaxing sunday to game...but no

thanks

 

Update: I've clean uninstalled the drivers and reinstalled but still getting the same message. Its like I have no graphics card anymore

Second update: Checked my drivers and am getting this for both my integrated one and AMD

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

 

Seems ive fod a temporary fix by disabling driver signature enforcement from my boot menu. If anyone has a longer lasting fix that would be great as I don't want to spam f8 everytime I restart my pc
