Hi, here is a description of my system:

Motherboard: Intel D845PEBT2 (includes 2 SATA connectors)
Processor: Pentium 4, 2.4Ghz, bus 533Mhz
RAM: one 512MB, 266MHz
Primary SATA connector: 120GB HDD, western digital
Secondary SATA connector: empty
Primary IDE connector: 80GB HDD, for backup purposes
Secondary IDE connector: Sony CD-RW (Master) and Lite-On DVD-ROM (Slave), cable select
Video: GeForce 440MX, 64MB, AGP 4X
Sound: 6-channel, SoundMAX Cadenza integrated in motherboard

Here is my problem: I buyed a Western Digital 120GB SATA HDD, to replace an IDE 80GB HDD. My motherboard has 2 SATA connectors already installed. So I installed Windows XP Professional, a few programs, Winamp 5.08 among them, some critical updates from Microsoft, Office 2003, a couple of games...

Well the thing is that when I am reading or copying files from the CD-RW or the DVD-ROM to the SATA HDD while I am listening to music, the sound twitches and the computer behaves really slow.

Any clue??? some tip for solving this problem? I am guessing that it is a software or firmware problem because it did not happen before I installed the SATA HDD.

Help!

Sounds like your motherboard's BIOS isn't letting the SATA controller and the sound card controller play nice wrt IRQ's. First check for a BIOS update from Intel. Also make sure you have the Intel chipset drivers installed.

BTW did you install Service Pack 2?

Hi,

I'm on it... I will check the BIOS and chipset drivers and update them if necessary. Tomorrow I'll let you know if it worked.
Thanks!

Updating the Intel INF drivers might to the trick, update also motherboard and general driver pack to be sure
