does anyone and i mean anyone have the answer to this. i have come to the conclusion the chipset is just dead. I have tried every single thing in original post all suggestions on every google search and in here i can find.

1. Uninstalled/ reinstalled driver straight from dell dimension 4500
2. flashed bios
3. chipset update
4. putting in 2 other sound cards that work just find in other computers
5. enable/disable in bios
6. lots of other stuff i can't remember

Only thing i haven't thought of trying is uninstaling service pack 3 for windows xp, because it has always worked before no problems. But the disk i got from ms is xp with sp3 slipstreamed on it cause i lost my original one. lol But then again i really don't want to wipe this thing or uninstall sp3, but if i have to i will!

no matter what, it installs the driver, but says there is a code 39 for it. Just puts the old yellow exclamation point on it in device manager. Same for pci sound cards yellow point! I not a genius or nothing but i am exceptional at fixing computers and i honestly think i have been defeated for first time ever in 10 years. Now i can probably change mobo out and make it work, but i need to know if this is fixable and i haven't found it, or if it really is hardware that is dead? Please lol
