Computer RAM?

When I bought my computer it had 512MB of RAM. Now it has 446. Can anyone tell me where the memory went? Is there a way to regain it? As you can tell, I don't know a lot about it.

Also, I need the 512 to download my antivirus. It comes free with my ATT membership. But if you know of any good, FREE antiviruses, please let me know.

Thanks.

Try creating a page file for virtual memory. This is a lot easier than buying a RAM chip which may cost anywhere from $40 - $1000+. Here is how you do it.

all ram is like that. this just tell you how much of the ram is not being used. you still have 512. To better improve your computer performance, i suggest upgrading to 1gb of ram.
It should be 448.You looked on the box or in the Manual-did you ever look really on your computer?

If you buy a computer that says 512MB that means it has a RAM from 512MB,but your Video card from 64MB uses that from the 512-so you should have 448MB.
all computer happens like that but if u want more ram u can buy it from best buy or anywhere else just ask
thats probably the amount of ram being used i suggest you get some more ram try this site it's great!!!!!!!!!!!!!
