Windows 7 has sooo many different options for audio it is confusing. If you right click on the (windows) speaker icon in the system tray and click "volume control options" you get one set of features.
If you click on the "sound" icon in the device manager you get entirely different results!
And lets not forget that your sound card probably has its own audio configuration utility!
I have found that sometimes you have to play with all of these programs to get the sound to work properly.
Getting windows to recognize the "default" seems to be the biggest issue.

MB was shorted. Probaly ruined it
No ever work on an MB if power is on

in Acer Aspire Series is using Intergrated Graphic Card.
that mean if you wanna Upgrade your Graphic Resolution,
you have to set to a bigger shared memory/RAM for Display Graphic Card/VGA memory from BIOS Setup.
for example if you using RAM 2Gb, and you can make your VGA(Video Graphic Adapter) to 1Gb.
But in My Computer Properties the RAM will Show only 1Gb.
Because another 1Gb of RAM you've use for VGA.
you can check it from dxdiag.
(for opening dxdiag > Click Start > click RUN... > type dxdiag > and Oke/Enter)

Try re-installing the drivers and see if the computer picks up the hardware on your next reboot. If you're having trouble getting audio from the front panel of your desktop, try using the back panel. If it works then the cabling inside of the computer to the front panel might have become detached.

all fans died, all 3, PSU, CPU and GPU?
2009 FAILED PLAYING a GAME
that means 2 things, or more i will do them all
first off do not hot swap any GPU Card AC cord to wall or boom blow up cards or mobo. (hot swap NOTHING inside a PC)
yes happens to 10,000's world wide gaming.!!!
not one video card told just the game. how sad is that.
it came new with VISTA then 2009 no OS told by you no hints.
causes all: seen them all I have.fixed them all (if possible)
1: GPU card with AUX 12vdc jacks 1 to3 not connected all if seen on card they are NEVER optional.
2: PSU overloaded by
3: wrong GPU driver loaded and remove old driver before card is replaced, then shut down and pull AC cord for 15 minutes
then load me gpi card driver next, nvidia or AMD/ATI. as the case may be;.
4: PSU BAD gee it ran for 9 years, amazing it did. caps bad there
5: MOBO bad caps left over from 2008? or older. Cap Plague.
6: any of 20-things in a PC shorts, bingo PSU shuts off under 1second flat.
7: PC, PSU or CPU or GPU card overheats it shuts down, for sure
near 90c, 50c is goal never allow near 90c, ever, case fans help.

we fix bad PC so seen it and we have way faster GAMING PC make right DIY)
did I get them all , seems yes. no?

the highest the video can go is 256meg and is adjusted in the Bios an depends on how much ram memory you have installed but yo can upgrade to a PCI-E video card.Here is the manual for the board.

ftp://174.142.97.10/manual/N68-S.pdf

firmware DOS(?) what does that mean, DOS?no dvd disk told of endless on earth and most being useless
only 3 kinds of disk work here.

MS instanller disk , no OS told at all (gee DOS OS?)OEM PC disk from say ASROC?or a home made clone of the same or off stinking rotten infected torrents/?????I see by you one clue you are the last man on earth installing 2001
windows XP on a PC mobo 2010 and with usless Nforce chipset there. pure junk now, AMD nforce, or VIA or SIS chips.
the OS XP is the F6 mode,, and F6 forces on a driver called a XP preboot driver (or vista) and must come from support page asroc..
XP is F6 married to a Floppy drive, gee where to get a floppy disk now>? huh, they be gone not, zero here in my town, for a decade
the usb driver here is usless, and is for RAID
turn RAID off in bios step 1.
new coin cell battery it is too old.
you will need to as asrock where is the XP preboot driver. for sata.
the instruction for xp , vista and w7 are not the same. to get those installers to work with Nforce JUNK..
best is avoid NFORCE MOBO totally.
