Hi, your friend's PC seems to have some connectivity or power issues. After checking the connections and cleaning everything, the problem persists. The GPU, RAM, and power cables appear properly seated. He noticed RGB lights changing when a program launches, but no display appears. Connecting monitors to another device works fine, indicating the issue is likely with the PC itself. His 3070 CPU is three months old, so it’s possible the GPU failed earlier. There’s also no signal when connecting the monitor directly to the motherboard. He has a Ryzen 5 3600 processor. Any other suggestions or experiences from others would be greatly appreciated. Thanks!

The only indication of a new issue is that it comes with a warranty if it fails. Could the GPU be connected via a riser, extension card, or cable by accident? Those connections have occasionally led to complications. There should be no signal from the motherboard; the port functions only when the CPU includes an integrated graphics unit, the G series chips for Ryzen. You may verify if the BIOS settings on the motherboard have been altered to support an iGPU. This adjustment could also create conflicts, since iGPUs sometimes clash with a dedicated GPU installed together. It’s likely possible if the setting remains enabled regardless of whether the chip has integrated graphics. Additionally, confirm that the PCIe power supply is delivering adequate voltage to the 3070, as this might point to a power supply issue.

It might be achievable by simply restarting the system. You can verify if the change occurred by observing whether the fans spin again or if the lights activate after a reboot.

Things can go wrong when starting up. I've encountered systems that stuck and needed many tries before working. This guide shows how to jump the ATX connector using a paper clip. You'll then verify pin voltages with a multimeter (make sure the ground matches on the same connector). It's wise to unplug everything for safety, but some users find it useful to keep a hard drive or other device connected so they can sense a load. Updated June 2, 2022 by An0maly_76 Added more details

The graphics card's connectors depend on whether it has built-in graphics. Check which ports it uses. If a port fails, test the others. Using a connector for a second monitor without proper setup won't show any output.
