The Problem: A couple of weeks ago my computer wouldn't start, absolutely anything; figured out that it was a dead motherboard so I ordered a new one (Asrock Z170 Extreme 6), and this weekend I installed it. At first, it wouldn't run due to an error code (19) which the book said is memory related so I followed the instructions of reseating everything, didn't work, reset the CMOS, didn't work, remove all RAM then reset the Cmos, Reset BIOS, it starts. It shows no error code, but when I start the computer and connect it to a monitor it says "Input Signal Not Found, Check Source and Wire": the monitor and wire do work. When I try to connect it to a tv that works it says Not Supported Format. I don't know what to do, at this point. Thanks
