I would first try to check for viruses and spyware. This is one of the major causes of sound issues. If everything else is ok with this laptop, then it sounds like your audio card might have a problem. Howver you might also have a problem with your speakers. Try connecting external speakers to you computer. If they work then it's your speakers. You can purchase those online from Ebay.
it is either your proccessor or your memory is bad find a plce that will check for free if they are good then your disply or vidieo chip is bad and the chip cant be replace but if it is the display then you should be able to connect it to another type of disply
It could as long as you install the proper sound drives for your usb sound card. This is important cause your laptop has to be able to detect the device properly.
you will be missing some device drivers - you can find them here http://www.acerpanam.com/synapse/forms/portal20.cfm?website=AcerPanAm.com&siteid=7117&areaid=2&formid=3394#results
Try downloading the appropriate driver from the Acer website. Note Acer shows your model of laptop having Nvidia Chipsets for Video and Motherboard, install the following drivers listed
Ok.. This is the downloads site for ACER support site. ftp://ftp.work.acer-euro.com/notebook/aspire_4520/vista/Drivers However there are two wireless LAN drivers in that directory. You should find out which one is yours. To do this click start->right-cllcik on computer. When the system window opens click on device manager located under tasks on the left hand side. When the device manager opens double-click on network adapters and one of the two devices(Atheros wireless LAN or Broadcom wireless LAN) will be listed. Download the respective driver and your wireless would be up and runnin' ftp://ftp.work.acer-euro.com/notebook/aspire_4520/vista/Drivers
