Windows XP Home. For the past two days my desktop would not turn on, so after some testing

I found out the power supply was dead, so I replaced it and the machine came back to life,

however since replacing the power supply the volume icon is no longer there (I did go into

Control panel> sounds and audio devices, I'm not a beginner, and I have googled the [bleep]

out of it but nothing has worked), I have downloaded the latest audio drivers (Realtek

AC'97), I also tried the original audio drivers from the restore cd's I was given when I

bought the machine but no luck. Also after the new power supply installation all four usb

ports no longer work. Currently my pc does have audio because I installed an old sound

card that was lying around. I also bought a four port PCI USB card. But it would be great

if I got my old sound card and USB ports to work. And last but not least I can no longer

burn cd's or dvd's even though i tried three different dvd burner drives (and one external

dvd burner) and four different burning programs (2 paid programs and 2 free). Is it

possible something on the motherboard got fried when I replaced the old power supply? I do

have three restore cd's is it possible to get the machine back to its original

configuration if I use them? Any advice folks.
