Hey everyone,
I bought my PC about three months ago, and it was running perfectly until I moved it recently. Despite my best efforts to handle it carefully, I've been facing a frustrating issue since then. Now, whenever I power it on, both of my monitors just display 'Searching for Signal' followed by 'No DP Signal.' At times it would briefly work if I reseated the GPU, but now it seems completely unresponsive. The GPU fans spin and the lights come on, but that's it.
**Here are my specs:**
- Ryzen 7 9800X3D
- RTX 5070 Ti (brand new replacement)
- Arctic Liquid Freezer III 360mm
- 64GB DDR5 6000MHz Kingston Fury Beast (2x32GB)
- 4TB Samsung 990 PRO NVMe PCIe 4.0
- MSI MAG X870 TOMAHAWK Wifi
- MSI MPG A1000G 1000W 80+ Gold ATX 3.0
- Alienware 4K (DP) and BenQ 1080p (HDMI)
**Things I've tried:**
- Used different DP/HDMI cables and tested both monitors — they're working fine.
- Swapped to a brand new GPU, same issue continued.
- Cleared CMOS as per the manual instructions.
- Reseated the RAM sticks.
- Tested the second PCIe slot — still no signal.
- The PSU powers on, the fans spin, and all RGB lights up but there's no video output.
It did work once after I set everything up but failed again after a full restart. What should I do next? I'm stumped on what the issue could be.

Have you tried connecting your monitors directly to the motherboard instead of going through the GPU? If you can get a display that way, it might indicate an issue with the GPU or its connection. By the way, what BIOS version is your motherboard running on?
It sounds like something might have shorted out when you moved your PC, or maybe the BIOS got corrupted after the reset. Have you checked if the PC powers up fully without the display? Any indication from the debug LEDs? If nothing shows, you could try flashing the BIOS with the latest version via the motherboard's BIOS slot.
Yeah, that might be, but what’s confusing is it works sometimes, especially right after I refit the GPU. It ran fine until I turned it off and tried to restart it. Shouldn't that rule out a BIOS issue?
I think my CPU doesn't have integrated graphics, so I can't test that way, unfortunately. No ports to connect to anyway.
