Can a dead motherboard still power on? Troubleshooting a used motherboard
I decided to build a 2010-11 era gaming PC for the fun of it, just to relive the PC I couldn't afford when I build my first PC.
Anyway, I ordered an Asus P8P67-M PRO motherboard and a 2500k off of ebay used. You can still get DDR3 fairly cheap new on newegg so that's what I did. I have an older but working TX550M I just replaced out of my current PC. I'm using a working GTX 660 as the gpu for now to test the system as I'm still waiting for the GTX 580.
The motherboard arrived well packed and in great condition from a seller with lots of feedback. Socket pins all appeared to be fine. Board is spotless and dust free, not a single bent pin or header. CPU also looked fine, no scratches or anything on the pcb or contacts. I put everything together, shorted the power switch header, the CPU and 660 fans spin up, but I get no video output. I try one stick of ram, the other, try it in the other slots(ram is verified working in another PC), try a different video cable, try a different monitor, try my old R9 Fury, try the graphics cards in different PCIe slots, nothing works. Used the clear cmos jumper, still nothing. Removed the cmos battery for a few minutes, put it back in, still nothing. Mem OK button, still nothing.
Is this a dead motherboard? It still powers on every time, the power led on the board always comes on, fans and PCIe get power, is there anything else I could be missing? I don't think it's the CPU because those are much more robust and don't have much to break, but maybe? Should I recheck the LGA pins?
One thought I have is that it sill might be the memory, because the manual says it supports up to 4gb dimms, but it would support 8gb dimms when they came out, and I have a 2x8 kit, which also isn't on the QVL list of memory sticks in the manual, but it's G.Skill Ripjaws V which everyone and their mother was using so I really don't think it should be an issue. But I do have a 2x4 kit of Ripjaws V coming soon.
I've got cmos batteries coming in a few days, maybe a fresh one will fix it. I also have a 3570k and a Z77 motherboard coming in soon, so I can also cross check the CPUs with each motherboard that way(unless I somehow got two dead motherboards or CPUs).
Sidenote: This is why I only buy motherboards with a debug LED display.
