Just bought new computer with Windows 7 Professional, put in my Soundblaster Audigy 2 sound card, disabled the Realtec card that came with the system, but the computer still doesn't acknowledge that new hardware is installed.

Yes you can. A Soundblaster Audigy FX would work. Be careful to get a PCIe card, and not the older style PCI card. Your PC ships with several free PCIe slots.
2 (total) / 1 (free) x PCIe 2.0 x16
1 (total) / 1 (free) x PCIe x4
1 (total) / 1 (free) x PCIe 2.0 x1

You should install the sound card in the PCIe 2.0 x1 slot if possible. If not any of the others should work as well.

Hello,

If this is an Audigy 2 ZS as the heading says, you can download the Win7 driver at:

Audigy 2 ZS Drivers

If it is not an Audigy 2 ZS you can select the exact model at:

Creative Labs Product Selection

Click Audigy and then select your model #, then click Next.

Thanks fro using Fixya.

try these motherboard settings:

1. try disabling your on-board sound chip thru your cmos/bios setup and uninstall its driver in windows.

2. try changing your pci setting from 32 to 64 to 128 thru cmos/bios.

3. if any of these setup options doesn't work, try asking the store from where you bought your soundblaster card to have it tested or replaced if it's still under warranty.

if you have a legal copy of windows xp, you should use windows update and it should automatically list your hardware drivers also.

You need OpenAL
