Hey,

I bought a new computer a few months back from a customizing company and have been having serious gaming problems. I finally think I've found the problem, because after disabling onboard sound, game performance jumped. But, after buying and installing a new sound card and loading drivers, performance fell back to its previous levels. I'm not sure if I just have a conflict with my mobo or what. Help please!

Stats:
Intel Core 2 Duo E6600
ASRock 775Dual-VSTA motherboard
1 GB DDR2 RAM
250GB Samsung 7200 rpm hard disk
BFG GeForce 7900 GS GPU
Sound Blaster Audigy SE
Okia 400W ATX PSU

An older guide but much of it still is pertinent:
