Suspected DWM malfunctioning

Hi,
i'm having an irritating issue, every couple of hours after i start up my computer, i get one of a number of small error boxes saying something along the lines of, windows IP has crashed or the color scheme has been changed, they don't seem to come in any order, and they don't seem to affect the computer's capabilities at all, baring the fact that they stop aero theme's from working, and revert it to windows 7 basic color scheme.
At first i assumed a graphical problem and updated my drivers to the latest from ATI(not the beta drivers) but that has had little effect.
I had a quick blast over google, but as i can't really narrow down my problem other than it seems to be to do with windows, and effects the theme, i didn't find much helpful and you guys were my next port of call.
Thanks in advance,

Tony

 

It has just brought up one of the many different error messages, and i managed to think on and print screen it, i was just scrolling through reddit when it popped up and to my knowledge the computer wasn't doing anything else.

 

I ran a Full computer malware scan and it didn't fetch up anything, and i checked the services and the ups seemed fine and was running, so i'm going to give it a go in safe mode and check the start ups now, i caught another one of the errors that popped up.
Also i tried disabling the aero themes myself and switching to a standard one and there is a marked improvement though the issue is still there.
