[SOLVED] PCI slots all stopped working at the same time, but PCIe still working.

[BlueServo]

Hi all,

This is my first post so I hope everything here is formatted and tagged correctly.

I have an Industrial PC with an ASRock IMB-781 Rev G/A 1.03 mother board. It has been in a rack for the past year, and yesterday I took it out to see about potentially changing a PCI card (this PC has 3 PCIe slots and 4 PCI slots). I removed the card for a short period of time, then reinstalled it and put the PC back in the rack. When I turned it on, I noticed that the card didn't show up in my Device Manager. I thought that I had damaged the card but put it into a different PC and it worked. After some troubleshooting, I determined that every PCI slot in the computer isn't working properly. Here is a summary of the PCI behavior:

• Cards plugged into the PCI slots (all 4 of them) do not show up in Device Manager
• There still seems to be some power/functionality in the slots because I have a PCI card with an LED that still lights up when
• There are no PCI slots mentioned in the BIOS (although I don't know if they were there before - I do see 3 PCIe slots that I am able to configure the speed)

Also, all of the PCIe slots still seem to be working fine.

Is there some PCI manager that maybe got messed up? I am at a total loss and after about an hour of research I haven't found anyone who is had this same problem. Any help is greatly appreciated

This motherboard?

Take a close look at the power connections.

Look for signs of something loose or damaged. Cable or connector port.
