My brother has this nearly 6ish year old asus desktop that he bought from the store. (http://www.asus.com/Desktops/Essentio_CG1330/specifications/) <- specs of the computer from the store. I replaced the gpu however with a gtx 650 as a Christmas gift a while back. It worked perfectly until this week. The desktop powers on, but there is no display recognized from the computer itself (black screen on monitor). I replaced the PSU with a newish one that I know works. That didn't fix the problem. Please help! Suggest any sort of fixes/tests I can do to figure out this problem!
-thanks in advance!
