I recently got my parts to build my new computer. I put everything together and then when I turn it on I get no picture on my monitor. I figured the problem could either be the video card (PCI Express x16) or motherboard. So I purchase a new video card and when I install it, I get no picuture again. No picture at all, no BIOS screen or anything. So I figured it's a bad motherboard. So I just purchased another mobo, and the same problem, no picture. I tried both video cards and no picture. I have everything disconnected. I just have the power from the PSU to the mobo. And the video card in the PCI Express slot. I just want it to get to the BIOS screen, but no luck. What do you guys think it is? I really need help. The motherboards are both 24 pins but the PSU has a 20 pin connector. I do have the 20 pin to 24 pin converter adapter. Can this be a PSU issue? I don't see what else it could be. Help.
