I have tried different drivers as well as using TGL drivers... But nothing works. I figure it is having my SCSI on same IRQ with my G400. I have tried playing around with IRQ allocations within BIOS, but every "tweak" I make, there seems to be a counter-action where both the G400 and SCSI(onboard mind you) are joined at the hip.
Could someone give me a hand in fixing this problem?

Yes, I agree that the first problem must be that SCSI sharing with the G400.

Looks like you have to physically swap cards around if redirecting IRQs in BIOS isn't helping.

It sounds bizarre, but many people have found that having the NIC share with the G400 is the only solution.

I assume that you have the SCSI card in PCI slot 1 (right below the AGP slot). That's why you can't separate the G400 and the SCSI card... those 2 slots share an IRQ.

Try moving the NIC to slot one and putting the SCSI card where the NIC was, and let us know what happens.

The SCSI chips are onboard my motherboard. I have no other AGP slot. =) I found what may have been my problem tho. A piece of software was causing my problems. Check out my other post for more details. Thanks for the suggestions tho.
