280x issue's since latest windows update/ati drivers

Question

Hello ,
Since a couple of days i have been having the weirdest issues with my system. It all started after i updated my windows and updated the ati drivers to 14.4. I would notice flickerings on both my monitors and out of nowhere when playing flash movies the screen goes berserk (always just the left monitor) :

if i would kill the program (aka firefox) then 50% of the time the screen would recover.
I tried 14.4 ,14.3 and now im on 14.1 rc 1 hoping this will work , however its also flickering again , or when i open a browser you can see the second monitor jump up and down for just 1 second.
I removed all drivers with DDU and made sure i did that in safe mode so that could not be the issue aswell. It dont think its the PSU since its on 12v constantly when under heavy load and its just 3 weeks old.
could it be an bios issue ? is there a new vga bios available for my card ? And has anybody ever seen this issue before , since i havent and i have seen a lot of broken weird things haha.
Rest of my specs in the sig are still the same.

Answer 1

update 2 : had 1x the same as the first picture , do notice that according to gpu-z my gpu core is running at 500mhz atm... It stays that way even when playing BF4 , but BF4 itself is as smooth as a baby.
i have manually set the clock to 1050 / 1500mhz in msi overburner and the gpu-z sensors dont change , but still the game runs fluid.
