Ive built a custom machine very nice and expensive but when I had it shipped back from japan to back in the states it came with a problem. It worked fine in japan when I used it. But when I got it back the video card had fallen out of it so I put it back in and started up the machine after checking all the wires and made sure nothing was broken. Everything seemed fine. When I started it I got no video output, but when you remove the video cable the screen says check signal cable. I tried multiple sli xpress slots and multiple video cards and everything was the same. Tested the power supply and getting the 12volts going to the video card. And fan works on video card. Now im just wondering could this be a bad motherboard or is there something else im missing here. And yes monitor works fine have it plugged up to another computer right now and working great. Any help would be great.

Thank you

A concise troubleshooting roadmap and what to gather next for , expanding on the helpful pointers from and without repeating steps already tried.

Begin with a careful visual inspection (use a magnifier and bright light). Look for cracked or lifted solder around the PCIe slots and chipset, missing/bent PCIe contact pins, torn PCB pads where the GPU bracket screws fasten, bulging or leaking capacitors, scorch marks, or a standoff touching the PCB. Physical damage is common when a heavy card shifts during shipping and can kill the board even if fans spin.

Next, capture diagnostic signals the board gives. If the case has no speaker, temporarily attach a small PC speaker to the front-panel header to hear POST beeps. Also check any motherboard POST/Q-LED indicators and note exact patterns or codes. If the board has a POST-code debug display or if a POST card can be used, record the hex code — it tells whether POST fails at CPU, memory, chipset, or video initialization.

Check power distribution beyond the GPU 12V: measure the PSU 24-pin rails (5V, 3.3V and 5VSB) and the EPS/CPU 12V under light load with a multimeter or swap in a known-good PSU for a short test. Faulty rails or a short on the motherboard can allow fans to run while preventing proper initialization.

If further confirmation is needed, bench-test the board outside the case (on an insulated surface) with minimal devices and document every result (beep patterns, debug LEDs, voltages). Photograph any visible damage and create a short log of tests and measurements. If the POST/debug data points to chipset or PCIe faults or you find physical PCB/solder damage, RMA or board replacement is usually the practical fix; BGA reflow is a temporary/uncertain repair. Finally, avoid repeated power cycles on a board that shows electrical faults to prevent additional damage while preparing photos and test logs for warranty or repair.

well if it got bumped hard enough to not out the video card it may have broke something else also,try and reseat everything .like heatsinc, cpu and ram, harddrive and try again .

Make sure HD is working. If you listen you can hear it spinning. As the previous post stated, reset the bios and pull out the RAM memory and reseat. To reset the bios look at your MB manual for the jumper settings or just pull the battery and let set for about 30 minutes. If there is a long beeping sound on boot up, you have a hardware device problem which is probably the RAM.

I reset the bios and the ram and checked the HD the HD i think is working im really not sure cause there is a lot of sound going on in the computer from fans and im not real sure i can hear it. I know what a bad HD sounds like and well it defiantly sounds nothing like that.

Replace the RAM with some RAM you know is working and see what happens. If that doesn't work replace graphic card with one that you know is working.

Replaced ram and tried other video card nothing changed. The geek squad at best buy said it was MB. But still checking everything possible before I replace something that may or may not be needed.
