I could not find good solution about my issue on PCI express x16 slot. As you know Z400 has two slots of PCI express x16. Usually I use two graphic cards. But suddenly one slot does not work. (slot number 4.) Slot no 2 works. I confirmed problem of this by testing same graphic card at slot no 2 and 4.
So I want to know:
1. how do I know this error definition? 2. how do I check pci express x16 slot health? Any software? I already used "HP PC Hardware Diagnostics Windows" but this program does not do motherboard health check???
Any suggestions are welcome! Thank you in advance.
