H97 Fatal1ty Performance not posting

Hello,

I have recently installed an H97 Fatal1ty Performance motherboard with an i5 4690 processor, XFX 550w PSU and Corsair Vengeance DDR3 1600 RAM. It worked fine for a day, but will now not post.

The Power Led lights, CPU fan spins, along with the PSU fan and one of the case fans, but there are no motherboard lights. There are no beeps and no video output.

I've stripped the system down to PSU, CPU and Motherboard, cleared CMOS, switched to BIOS 2 but none of these have made an difference. I have also tried an old PSU, but again, no post.

Can anyone suggest anything else I can try, or should I RMA the board?

Thanks

Nigel

You said no mother board lights are on when you try to start the PC. Is the Power LED that lights up on the PC case, or on the board?

What other LEDs/lights did you see that were lit up on the board at one time (apparently) no longer lighting up? Some boards have a BIOS selection LED when the board has dual CMOS chips like yours, for example.

Do you use a wired Internet connection that is connected to the network port on the IO panel? If you do, with the PC shutdown, connect the network cable to the port and if the PSU is off, turn its switch on. There are two LEDs at the top and bottom of the network port, do any of them light up with the cable connected and the PSU on?

Do you have a POST beep speaker? If POST completes successfully, you will hear one short beep. There may be an option in the BIOS to turn the POST beeps on and off, so if you never heard the single POST Ok beep before, and you have a POST speaker connected, that option is disabled.

If you do not have memory in the board, it will not POST.

Since this problem happened so soon after building the PC, the board might be the problem. Are all the other main components new as well?

Thanks, folks.

After following almost all your suggestions, I was ready to RMA. Then, as I had to take the CPU out anyway, tried the final possibility of reseating the CPU (I wanted to avoid replacing the thermal paste unless necessary).

This seems to have done the trick - it boots up correctly now. There were no bent pins on the socket and nothing on the CPU. So that's kinda strange, especially as it had been working ok for 24 hours.

I've just put the PC to sleep, so will see if it wakes up. If it locks again, I'll need to figure out whether to RMA the Motherboard or the CPU.

Thanks again,

Nigel

Looking good, so far. Thanks for all your help.
