This sunday I decided to upgrade my system from XP Home
OEM to XP Professional.

I had bought the software a couple of days ago and I
thought it was going to be a piece of cake. Here I am,
almost 12 hours later with no sound coming out from my
system. The PC is just saying that I don`t have a sound
device installed.

I have a HP Pavillion a210m, do you have any ideas?

I thought all the drivers came with XP Pro... but I can´t
seem to find them.

Ideas, anyone?
X!
