Press DELete key to enter BIOS Setup.

Use Down Arrow key to highlight - Fox Central Control Unit
Press the Enter key

CPU Frequency Setting should be set to 333 (333MHz)
Intel processors are 'Quad Pumped'
333MHz x 4 = Approximately 1333MHz. (1332)

Send your email address to me by Fixya comment. I've audio drivers. Let me know, whether can I send it to you by return mail.

Sorry its too early to expect a sound driver in Win2k8. Give more time for programmers to make, say 6 mos. Sorry. Try sending an email to HP about the problem, they might give you their secret driver. Anyway your too advance in OS. good luck.

the audio driver will be specific to the motherboard you're using. You usually can find the driver on the manufacturer's website.

HP Compaq DX7400. You'll need to select Windows XP Home or Windows XP Pro: http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=3604993

Yes this motherboard is compatible with the Intel Core 2 Duo E6550 processor since the maximum processor support of this motherboard is core 2 duo LGA775 Socket so everything should be fine between these motherboard and processor.

Go to this website and put your product key and download the driver.
