Let's try and get you booting again WITHOUT the new USB card installed.

NOTE: You'll need to reconfigure any settings in the BIOS immediately after preforming this, so now's a good time to breathe and take a few minutes to make notes on what you need to change after it boots, hopefully, but before the OS loads. ie: disks to AHCI or RAID, voltages, etc etc

1. Pull/disconnect the PSU from the wall outlet
2. Pull/disconnect the PSUs 24-pin power cable from the MB
3. Press the cases Power Button and hold it down for 30 seconds
4. Pull the CMOS battery, noting its orientation in its holder

5. Now lets clear the BIOS



You'll need some steady fingers and something small and conductive at its tip.

In the pic above, directly over the R in RoHS, is the CLRCMOS1 pads that you'll need to short out in able to clear, not reset, the BIOS. You only need to short the two pads for 3-4 seconds, that's all.

After shorting the pads, and nothing else hopefully , replace the CMOS battery properly in its holder, reattach the 24-pin power, plug it back into the wall, and, fingers crossed, she lights up like she should.



Whats the Make and Model of the PCIe card you have there?

My ASROCK C2750D4i box will no longer POST.  Powered it down last night to add a USB 3.0 card and when I turned the system back on, the fans spin for 2 seconds and the whole board powers back down and will not respond to the power button again until I completely unplug the power supply from the wall and reset the whole board.

I removed the PCIe card thinking it's the problem and it still won't POST.  The board is getting power because the fans still come on when I press the power button, but it just shuts down right away.

Did I fry my board adding the PCIe card?  I've tried switching to a different power supply, resetting the BIOS by removing the battery.  Removing all of the drives, reseating all of the DDR3 RAM.

I can still get to the Megarac SP BMC/IPMC console.  No major errors that I can see.  Anyone know how to fix?
