What's UP Freaks???

No sound, no USB's: Going Maaaaaaaaaaaaaaaaad!!!
But lets just talk about the sound, and not my dimentia...
Running: XP home Sp2, all updates included (problem?) Intel P4, fic mobo, 478 socket, with 845g intel chipset, and AC 97 sound Avance/realtek.

I though the problems wer casued by some hijacking b.s. and maybe, but i doused spyaxe and scvhost( not svchost), so cool I though my capabilities should return, but now I'm thinking I didn't eliminate all the bugs, and hoping that it's not shot . I've reloaded the drivers for everything i can think of, chipsets, soundcard, ide, and other controllers, but still nothin'. But Soundman.exe runs in the program manager, however, in the contol panel, sounds and audio, I still have no audio device. There are drivers in sound and audio section in the device manager, but they seem to be the windows ones. but also, the sounds are set to the unimodem. What gives?? is my little modem not acting as a correct bridge (pci) to allow the reading of the sound card.( and USB's) or could it be that the system registry was muffled up by the gremlins and the assignemnt values are all screwed up???

Oh yeah, I checke dto make sure the device were enabled in the bios, and they were'nt, i 'nabled em, but still no function. Has anyone heard of all this going down, and a remedy? I'm looking for the answers from the masters of the universe, or anyone who knows what's up...

So I'm really looking forward to everybody's help, Thanks- AAAOoooorhhhhh
