Also the last couple of days, my computer has benn turning itself off ater sometimes many hours and sometime just a few minutes. Can you suggest anything I might try to fix my problems?

If your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers or uninstall
click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the
(((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settings there
check all power leads from motherboard to hard drive and all of your cd/dvd drives make sure the connections are good and not faulty and there is no dust built up on them
another possible reason could be a memory dump you might be running to many programs at the one time placing to much strain on the CPU also you might not have enough RAM random access memory to check what is running when your computer is running scroll to the bottom toolbar right click select task manager applications and processes if you see something you dont need running select end now to check how much ram you have click start right click on my computer select properties you will see all of your computers details another way to check how much RAM you have click start all programs accessories system tools system imformation all of your computers imformation will be there try uninstalling a few unnecessary programs then click start run type cmd then type chkdsk/r/f which will scan for and attempt to fix any bad sectors and automatically fix any corrupt files on your hard drive this will schedule on a restart don
