Bought a used pc specialist pc from eBay, worst case scenario I get my money back. Current issues: Powers on, lights up, GPU fans don't spin but there's 2 solid blue lights. 1 long beep, 2 short beeps then stops. Motherboard has red then yellow lights on 2 sticks of ram.

With 1 ram stick there are no beeps and no yellow light, but still no signal. (Might be defective ram stick or slot, only does it with the 2nd ram stick?) DP is plugged into the GPU, GPU is plugged in properly, CPU has been reseated still no dice. CMOS has been replaced and reset. Tried 3 different power cables, 2 different displayport cables, a different monitor etc.

I've tried literally everything short of taking out everything and re plugging back in, flashing the bios, and resetting the CMOS battery with a screwdriver (I used a new battery instead). Apparently it was "working before delivery", but since arrival it's been a dead end. Just no signal/picture, even on my brother's monitor. I'll be honest with y'all, it's doing my head in. Please help.

As you probably know the beeps are correlated to memory issues. Have you tried other ram sticks? If the same thing persists maybe it might be the motherboard. Can you please list your specs so we can properly suggest ideas. Other than that if your GPU and RAM work on another computer try to refer to a manual pertaining to your motherboard to further debug the problem.

Hi there mate, tried other ram sticks, didn't work either. I tried it with only 1 ram stick, and the beeping stopped, but still no signal. I bought it from eBay sorry, and I'm not extremely advanced you see. Specs: r7 3800x, rx 5700xt, 16gb DDR4 Corsair vengeance ram, 2tb HDD, 512gb ssd.
