I'm working on a GA-X58A-UD3R and can't see POST, BIOS, nothing. It's currently on a workbench so I jumper 2 pins together to power it up. All the fans run and it doesn't shut itself down. It just sits there, mocking me. The only LEDs on are PHASE LED and DDR PHASE.
I know the monitor works and I've tried 3 different video cards both VGA and DVI. I swapped out memory, reseated the CPU.
I must be missing something basic. Please tell me what it is...
Both power cables are connected. I do have another PSU, but it'll be pain to get to. The workbench is a large, horizontal wood surface with various tools and computer components scattered haphazardly. The board is just sitting on brass standoffs and the power switch is just a header with stripped wires that I touch together.
No luck. I was hoping there was something big, dumb and obvious I was missing. There's nothing with the power switch or reset headers or the board not being grounded? I guess the next step is to try another PSU?
It is bare - I mentioned headers because the paper clip thing is what I'm doing with a header that has 2 stripped wires. I thought maybe it needed something more than that. No crazy OC stuff and it was working fine. PSU is 750W. I'm going to pull another psu out of another computer and try that. Weird thing is it acts like it's booting I just can't see it. I put a temp sensor on the cpu sink and as it's sitting there it warms up to about 43c, fans are acting normal, never self powers down.
I also reset the CMOS.
Connected to it are:
1 stick of RAM (changed)
1 HDD (changed)
1 USB keyboard
1 PCIe graphics card (tried in different PCIe slots, tried different power cables from the PSU and tried a card that doesn't require power)
1 header with 2 stripped wires to manually flip the power switch
I tried another power supply but the other one I could get only had 6 pins for the cpu power connection. I went ahead and tried it with the same result.
I pulled out the CPU (again) and don't see any bent pins or anything else out of the ordinary.
I guess either the mobo, cpu or possibly the psu is toast. I have no idea how though. All I did was take everything out of the old case and put it on a workbench. (WAS about to install water cooling and move into another case)
Any tips on how I can narrow this down? I want to order and replace whatever is bad asap.
It lights up and nothing is against it. I guess I'll give up and buy a new one. Any suggestions? It needs to support 2-way SLI and have a bingo light. It will eventually be a really shiny, flashy computer that will be in an office lobby. It's going into an open Banshetto 101 case so it needs to look good.
