Video on cold boot, but not warm boot?

By bloommike44 ·

I have a ASUS P5B-E motherboard with a MSI NX7600GT video card. If i cold boot the computer, video works fine. However, if I warm boot (ie restart) then theres no video. I already tried a different video card and it does the same thing. Defective motherboard or is there a setting or something I'm missing in the BIOS or power settings?

Sounds like the PCIe bus isn't reinitializing

This problem is common among some PCI express bus motherboards in which the bus doesn't go through a bus reset, thus reinitializing data to the PCI device. I'm sure there is a setting in the BIOS of your motherboard to allow for bus reset upon reset. Also, shut off the APM/ACPI features in the BIOS and see if the problem goes away.
