Windows PC, correct?
If you have a surround sound configuration try setting it to stereo before launching diablo 2.
Make sure you update to the latest patch, if error on patching run D2 as administrator.
Since you said you've tried using holy shield, was this the first time D2 was installed on this PC? If not, did it work before?
Did you download D2 directly from Blizzard?
