Hi Paul,

Thank you for your reply. I do not overclock my system. I don’t want to damage my system or reduce its lifespan.

My system is the following:
Intel i7 2600K
8GB Corsair DDR3-1600 RAM
Gigabyte P67A-UD4-B3 motherboard (with the latest BIOS installed)
Creative X-fi Titanium Fatal1ty soundcard
Antec 1200 v2 case
Enermax Revolution 1020W
2x Club3D 290X BF4 edition in CrossfireX
Windows 8.1 Professional x64 legal (with all the latest updates installed)

I totally formatted and reinstalled my system two weeks ago.
I don’t have a chipset driver installed. I can try that.
My sound driver is up to date.
