No Audio Device found/cannot system restore

Hello,
I have had an issue for acouple of weeks. I am currently in Iraq and dont have my xp disk otherwise i would of attempted to reformate that whole computer by now, anyways to the issue:

1) I cannot seem to be able to shutdown/restart my computer. It will go all the way down to saving my settings then just kindof hang around. Finally i will get a black screen when but wont kick back over to reboot. All the lights stay on as if it where still running. As you can see, it makes it difficult to do a system restore even because it cannot do a proper reboot. I have to hit the power on the the laptop to kick it over.

2) Around the same time this started to happen the Audio went out. I have tried to re-instill drivers but still no luck. Even been doing some looking around with SP2/SP3 and have tried what i think has been all but still open to suggestions.

Heres some system information, i just copy/past out of it
