i was alt-tabbing out of a fullscreen game on my home-built tower when teh whole screen just went black. audio kept going for a second, then stuttered, then teh picture came back with a little notification that teh display driver had stopped responding and recovered. this started the same evening i installed teh AMD Catalyst Radeon Display Driver 4.2 (Windows 98/ME) udpate. heres the message i keep getting:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
it happens maybe twice an hour now. before the update, zero problems for months. I dont want to start blaming the hardware if this is just a bad driver, but I also dont wanna ignore a card thats on its way out. where do I even look first?
