Sorry 'bout that:
Processor: Intel P4 with 2.88Ghz
RAM:640 mb DDR (Weird number for RAM memory these days)
Video Card: ATi Sapphire Radeon X1600 pro
Sound Card: VIA AC'97 Enhanced Audio Controller
Mother Board: ASUS P4V8X-X
Although the Audio problem has been fixed, it's still odd that without any use over a week can cause an Audio loss, besides from running a little worse than usual.
It's kind of hard to help when we know nothing about your system or what it's doing (or not doing). Is it dead as in not bootable, or just having sound and video problems?
Dying actually.
I'll try to install the latest drivers for everything, see if that works.
