Hi. A couple weeks ago I turned my computer on and I got no vga signal. I searched the forums here and dwindled it down to either a graphics card issue or motherboard issue going by the most popular responses to the question. I replaced the graphics card first and it didn't help. So I just replaced the motherboard and it still didn't help. I've tested the tower on another monitor. No luck. Can anyone tell me what to look for next? No beeps on either mb when I start even though I know the latter is good. This is really driving me crazy. Thanks

It's possible that your CPU may not be properly seated, but seated enough that the BIOS thinks it is getting good contacts (so no beep code). Similarly, this can happen with RAM as well (the BIOS recognizes it, but the connection isn't completely solid). Other thing to try is if you have GPU through the CPU (newer i series processor, 4xxx or 3xxx and some 2xxx or an AMD APU), try the onboard connector and see if you get signal as well. If you have another PCI-E slot, try the card in that slot, or if you have another PCI-E GPU, try that in the slot as well. That should narrow down what's going on.
