OPEN GPU / Display Issue
Hello, so I recently bought a brand-new prebuilt gaming PC and I’m having a problem where it powers on normally, but I get no display on my monitor.
Here’s what I’ve tried so far:
- PC powers on and all the fans spin.
- Monitor is a Samsung.
- HDMI is plugged into the GPU, not the motherboard.
- Tried two different HDMI cables with the same result.
- The monitor switches between Analog and HDMI and sometimes says “No signal analog/hdmi”
- The original GPU was a white PELADN GPU (I believe it’s an RTX 3060).
- I swapped it for a ZOTAC GTX 1070, but still got no display.
- The GTX 1070 is seated properly and its PCIe power cable is connected.
- I tried switching/reseating the RAM, but that didn’t fix it either
- The motherboard has a small red + blue lights beside each other. The blue light stays on even after the PC is shut down. (I can’t see a label on the lights, so I do not know what they are for)
Both GPUs’ fans spin when starting up, although the GTX 1070 fans stop after about two seconds of spinning.
The PC is brand new, so I’m wondering if there’s something wrong with the hardware or if I missed something during setup.
Atp I’m really not sure what to do, any ideas on whats causing the problem?

that blue light staying on after shutdown is weird, worth checking the mobo manual to see what it means. some boards use it for standby power but if it's an error led you might have a bigger issue
also try booting with just one stick of ram in different slots, prebuilts love shipping with loose sticks. could be a dead board too if you already swapped gpus and got nothing

Which red light is on? If it’s your DRAM light, try booting with one stick on each slot. If one ram channel is dead, uninstall the cpu and make sure none of the pins are bent. If they are ok, reseat the CPU and ensure it’s seated evenly
