Alright, so here it is. I currently have an MSI 970 mobo, AMD 3850, 16 gigs of vengeance ram, evga 750w psu and replaced a working nvidia 960 with an evga 390. After installing the the 390 my computer failed to post so I plugged the 960 back in and the computer still refuses to post. Everything worked flawlessly prior the installation of the 390. Again, monitor is black, keyboard and mouse don't come on, no beeps, but the system fans and LED's all.come on. Any help would be appreciated.
 
Solution
Try clearing the CMOS (unplug the power cord and remove the CMOS battery for a minute). Remove the RAMs, start the board and, if there's a case speaker connected, see if any beeps.
