I have acquired a Pentium 3 PC with 650MHZ last 2003. It was a second hand pick for me. Now, I have already upgrade its OS to WinXp but the built-in sound card is not working and it has no device driver. The only info about its motherboard is it was an ECS Brand Motherboard.

Support Information:
Device Type: BIOS / Motherboard
Manufacturer: ECS
Model: Built-in Sound Card
Interface: PCI / ISA
Operating System: Windows XP Professional
Age of Device: Not specified
FCCID:
