"application has been blocked from accessing graphics hardware"

So I recently built a new PC. I have the AMD Radeon R9 280X GPU, I have installed and the most recent drivers. Motherboard and bios all has most recent drivers.

I was playing Guild Wars 2 just fine for 6 hours last night, logged out, shut down no problem. I boot up today and every I open up a game it gives me this message and crashes the game. It does it also when I try to change the resolution.

"application has been blocked from accessing graphics hardware" is the message I receive.

So far I have tried reinstalling the drivers and the catalyst and I restored the system to two days ago and it still is giving me the same problem. I'm hoping it is not a hardware issue since the card is only a week old. I find it odd that it worked well last night and now it doesn't when I have changed nothing.

The GPU is working somewhat because I am able to mess with the settings such as fan speed.

Any help is much appreciated.
