|Why have you not made any further posts in your ONE other subject about the Satellite L20-101 ?|
If this subject is about the same computer, you should have added this problem to the OTHER subject, and you should have told us what you did and what the result was after my last post in the other subject (response 11).
Was the sound working fine previously ?
Have you attempted to install sound drivers, then your sound screwed up ?
Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:
If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibility, on another computer if you need to.
Seagate's Seatools will test (almost) any brand of hard drive.
Do the long test.
The bootable Dos versions of SeaTools can be used even if Windows is not working properly.
If the hard drive itself tests okay, any data problems found can be fixed, one way or another.
"my pc" doesn't tell us what type of computer you have.
A "PC" is merely a term that most commonly refers to a computer than can run a Microsoft operating system - it can be a laptop or netbook, or a desktop computer.

Is that the subject computer ?
PLEASE type letters in the model name in capital letters so they're easier to read.
E,g Toshiba Satellite L20-101
Most people who start a subject on this site are in the US.
If you're NOT in the US, please state which country you're in, or which country the computer was originally sold in, if that's different
In this case, there is no Satellite L20-101 model support on the Toshiba USA web site, and searching on the web with that finds no useful "hits" regarding support for it
The proper sound drivers...

The headphones jack on laptops and netbooks has a mechanical switch inside of it. It's supposed to disable the sound from going to the speakers built into the laptop or netbook whenever you plug a plug (on a cord) into the headphones jack.
If you have plugged into the headphones jack a lot, it's common for that mechanical switch to malfunction. You could try plugging a plug into the headphones jack, wiggling it, then pulling it out, that may get one or both speakers working, but the only real solution is to replace the headphones jack - that's an item frequently replaced by laptop repair places.
OR - you could make do by plugging amplified speakers into the headphones jack.
