Hi just wanted to let you know I haven't had any crashed in a weeks now.
I had no freezes after reinstalling the GPU drivers and adjusting the energy management to High Performance like Antman suggested. After a day or so I reverted the energy settings to the default settings just to see if it changed anything and it did, I had a freeze not long after. After setting the energy mode back to High performance the system is perfectly stable now. So it's either that or some Windows Update that installed itself automatically did the trick.
Anyway for everybody having similar issues: try setting the Energy Management setting to High performance.
