Issue encountered during installation of updated components alongside legacy hardware.
Issue resolved, refer to the discussion below for details. Hello everyone – thank you ahead of time for your assistance. I recently upgraded my personal/work build and wanted to repurpose old components for a new PC centered on emulation for 70s to early 2000s games. My CPU (Ryzen 5 3600) and motherboard (MSI B450 Tomahawk Max) were originally from my personal rig and served as my main components for about a year. I’m aware these parts are compatible. I purchased two 4GB DDR4 sticks at 2666 MHz (PSD48G2666K) and later bought a 4GB card from GT730 with a Fermi or Kepler architecture. I also retained a 500W quiet power supply and a 240GB SATA SSD for booting. I connected everything once the card arrived, but the system failed to start. When powering on, the motherboard’s back lights shift from white to red (confirm with EZ diagnostics – no lights on CPU/VGA/DRAM/BOOT), yet I see no signal from the card. I’ve tested two monitors and all outputs (DVI, VGA, HDMI). The card is correctly seated in the PCIe 16 slot (Gen 3), and I’m connecting monitors directly to it, not the motherboard. Previously, this board housed a 2070 Super and 32GB RAM at 3600 MHz; fans spin up on power-up, but no signal appears. A few observations: when monitors are connected, they repeatedly reset before entering power-saving mode. When unplugged, they stay idle and show a “Searching for signal…” message. I’m certain this isn’t due to a habit or data transfer, but rather something else. Lastly, I upgraded my rig from a 500W to a 1200W quiet PSU. Since both are from the same brand, I kept cables organized – attaching the 500W cables to the 1200W unit and using the latter’s cables with the new PSU. This shouldn’t affect performance. Thanks once more for your support. I’m still unsure what to do next!
Not always. Corsair uses several cable connectors in their products. I’m not familiar with Be Quiet!, but it could be relevant. That said, this doesn’t seem to be your concern—if you experienced this, you should have noticed smoke. My initial idea is it might be a GPU issue. Have you tried running the 730 on another machine to confirm it’s not dead? It wouldn’t be surprising if the card wasn’t functioning properly or didn’t match its specs. Another possibility is that the board was originally set up without CSM enabled, so it needs to be activated in the BIOS. The board might default to headless mode, not requiring a GPU to start, and get stuck at the setup screen. You might need to press F1, then ESC, and enter in that sequence to load the operating system.
Thanks for your response. I proceeded with the key combination now. I haven’t used the 730 in my other system (intended to skip it due to potential issues), but I’ll try soon. Unfortunately, the key didn’t work—every fan continued spinning, the red strip stayed lit, and the card remained inactive. I might test the 2070S in this setup to check for output from other components, but I’ll keep the GPU conservative as a precaution.
I’ll also try this early tomorrow (sorry it’s late here and this part has already annoyed me a lot). When I first turned the computer on, I noticed my P8 CPU connector was only halfway plugged in—maybe the other half didn’t click in at all, and I never realized. Even after reseating everything else, I still couldn’t get it working.
If it's a fully modular PSU, re-seat it at the end. I've noticed that this often resolves the issue.
Resolved this thread as the problem was fixed. Uncertain about the fix, but I reset the cables—everything was plugged in and firm before reattaching—and cleared my CMOS again. I also shorted the jumpers for 30 seconds this time. After restarting, it works perfectly! The drivers were tricky to locate for the GT730, but the system is now ready for emulation.
