No Audio Device

I'm new here and kind of slow at this computer tech stuff, so please bear with me. I recently rebooted my computer (Windows XP) because the sound wasn't working, something was up with my printer, and plugging in flash drives/camera freezes the computer. I figured if that after I reboot it, it'll be back to normal but its not. There is no volume control and everytime I try to play music or do anything that requires sound, I can't hear anything. A message would pop up like "No audio device". I have read other forums but they either didn't work for me or I just didn't understand half the things they were saying.

Also, I keep getting this message that says "Power surge on port hubs". I am assuming the port hubs are the things that you plug flash drives, iPODs, etc. in? It won't go away, and my computer freezes whenever I plug in a flash drive...

I'm pretty sure I need to give more information about my computer in order to get some help, but I don't know what to look for. Please help me

 

Have you run a virus scan recently? It sounds like it could be your power supply unit going bad if there are power surges on the usb hub. If it is the power supply it can be very very bad for your computer.

 

what are your specs of your computer and how old is it just out of curiosity and how long do you usually have it on, do you leave it on or do you shut it off at night?

 

this computer used to be my sister's and shes had it for about a little over a year, there weren't any problems with it. she got a new one and gave this one to me, and i've had it for about a year now. there werent any problems with it but just recently (about a month ago) i scanned for viruses but there were none. My speakers were working fine but then the sound would cut off half way in the song (but it would still be playing) and suddenly the power surge message pops up (im assuming from my printer because its the only thing plugged into the hub port, but doesnt make sense because it's always been plugged in there with no problems) then i plugged in a flash drive for some documents saved from school and it would freeze on me. i tried this many times and each time, my computer would freeze. after that, i rebooted my comp and now its still the same except my music wouldnt cut off half way, there just wouldnt be any sound whatsoever

i usually have it on for about 8 hours a day on school days (monday-friday) except this week because i'm spring break. i almost always shut it off at night except maybe once or twice every 2 months i leave it on overnight

 

are there people on this forum??? confused :cry

 

well you can try to update your audio driver, it might be a chipset driver also. Try to update those two drivers and see how you fare.
