Hello, I have the problem with the working Asus Xonar DGX PCI-E soundcard on Intel DH77KC, latest bios 1018.
After power on, computer stops at Intel Desktop Board logo, even F2 no responce. Sometimes Windows is booting, but in this instance no device in device manager. I've tried to disable onboard audio, this is in no way affect.
But, when I've disabled in the bios "PCIe ASPM Support" or "peg only", sound card is starting and working normally (by default ASPM was on).
Does it incompatibility, or warranty case of motherboard/sound card?
My specs: Core i5-3570, Radeon HD7850, 1x8GB RAM, RAID-0 WD10EZEX.
