Hey guys,
Some of you already know I'm running a new FX chip. Everything seemed to be going fine until this.
I tried to load Portal 2 up and I get the following error during the Portal 2 loading screen:

I'm not sure what that error means however I think it might be something to do with Ram.
Also note that ever since I got that error, my system seems to be unstable. I've not had a BSOD error other than that in Windows, however I have had one time my computer just decided to shut everything down, and restart itself like a normal windows process.
Any idea what could be the problem? My initial thought is RAM but after reading my error again, is it a CPU issue?
Thanks!
