Lost both onboard sound and front/rear USB

I'm wonderind if both these onboard devices are linked somehow. Haven't made any hardware or software changes. Computer started giving 1 beep at startup. No conflicts in Device Manager. WMPlayer reports no sound devices installed. Is my motherboard dying? Emachines T4511 with Trigem, VG31 motherboard made by FIC. 478 socket with P4 2.53 ghz. Is this situation worth risking a sound card on? Any help appreciated.

Link to MOBO specs.

 

After submitting previous post, my power supply went down. I replaced PS hoping it might fix sound/usb issues but it didn't. I guess I'll try a sound card. if it doesn't work I can use it on another pc or new motherboard if I need to replace this one.

 

Picked up new sound card today and it works great. Have had 5.1 surround speakers for 4 years and just got to really hear them for first time today. Guess I will keep my mobo after all. Not really worried about usb but if I need to I'll add card for that also. Don't know what caused onboard sound/usb to "konk out" but I consider the matter resolved.

Don't mind me I'm just talkin' to myself!
