Asrock Z77 Fatality Pro Black Screen

[neil73]

I recently installed a Creative Zx Soundcard in my system. After a couple of days I started having black screens a couple of times a day. I never had this problems before the Sound card was installed. Tested ram, moniter and gc but turned out to be the Creative ZX soundcard.Once removed and drivers cleared no more black screens. Sound card was installed PCIE 5 and GC PCIE 2.
Please help! Not sure how to solve this. Thank you.
