i am totally computer blind and i mistakenly removed something from my computer since then i have lost sound and i think my printer as been disconected. all internal checks have confirmed the sound is switched on, volumn is turned up to max but i still have no sound
It's the automatic updates that corrupt the sound and printer drivers, not you. This happens all the time, but not to everybody. Just on certain computers, especially older ones.
Double click the speaker icon in the lower right hand of the desktop, this will bring up the mixer, or single click to bring up the volume control.
But in case the volume is missing, corrupted, or the audio is otherwise non-functional:
you check whichever audio was installed:
click start, control panel, add remove programs, look at the list...
which audio software is shown on the list? delete it, restart the computer.
now visit the motherboard manufacturer or computer manufacturer's website
look up your computer drivers by model number
download the latest audio drivers, save on the desktop...
turn the antivirus off,
if you have multiple security programs installed, turn them all off
(your driver may not install if security systems are turned on)
now load your new audio driver, restart, turn the antivirus back on.
Let the forum know if that solves the problem. SGM
