So A few weeks ago I had a failed motherboard, so I ordered another one after about a week of debugging and it has arrived today. The old motherboard is a Gigabyte Z87X-D3H and the new one is a Gigabyte B85M-D2V.
So I put it all back together and found that when I power the system on, the fans from the power supply and graphics card spin, but then stop after a moment. Nothing happens on screen or anything.
everything is connected right, cpu fan header is connected, and I tested the PSU with the paperclip method and it worked. I should also mention that the Power supply fan only spun as long as it does when connected to the rest of the system during Paper Clip test
I am really stuck on what is happening and I would really like to find out what is happening.
Take out your graphics card, put just one stick of memory on your board, disconnect all hdd's and odd's and the only fan you want connected is your CPU fan.
Test and see if you can boot. (make sure you plug your monitor into your on-board graphics)
Look in the manual for the bios reset pins and just see if resetting the bios gets you to POST.
See if your model of cpu is compatible with the board without a bios update. Some boards need a bios update to work with certain CPU's. What is your CPU model?
Take of your CPU cooler and CPU. Have a real careful look at the pins on the board. Make sure no pins are bent.
I have had power supplies that test ok even on a power supply tester but they will not work under load in a system. Do you have access to another PSU?
Unfortunately I have no PSU to test it. Is CMOS the bios clear thing? That's what the manual said and it did nothing. And apparently the cpu is compatible with the board. If you need any details the specs aware:
Lets just double check as there is multiple revisions of the motherboard. Look on the board and confirm the revision. Hopefully they kept it in the same place with each revision:
No I have not checked the pins but I am not sure that it would be a problem, it is a fresh new board, the pins where fine before I put the CPU in, and I put that in gently. It does say 3.0 is compatible with the cpu. It seems to me that this is simply a faulty PSU.
I would say so to. Maybe you have a local pc store who would be willing to test it for you? Bring the system in and they will probably put a test PSU in to see. I know we would do that type of think when I used to work at one.
