I have had a sound problem form weeks, several solutions tried and failed. I was able to restore sound using my Intel Driver disc that came with my computer. As far as I know it installed only the Intel Audio Studio drivers.
However, on my desktop is a folder called WDM.
In this folder are many files.
Under help it shows this info:
Windows XP professional
version: 5.1 (build 2600.xpsp_sp3_gdr.080814-1236 : service pack 3)
I've done nothing, knowlingly, to put this on my desktop.
1. Why is it there?
2. Where should it be?
I see SP3 in my add/remove program list. I do not see service pack 2.
