R.a.m.

You would need the model number to find out if you can add ram. There are limits each motherboard can handle. You also need to know how much you already have.

You have to have pairs of sticks if you have more than one.

To find out how much you have start/accessories/system tools/system info and in the list on the right it will tell you total system memory.

The model number should be on the back side or bottom if you don't have it written down. Also you need to know the manufacturer.

I might add that there are some very cheap computers around if yours is old. Some of the older ram is pretty spendy.

Also, if your computer has been running fine in the past more memory might not be what you need. Why do you want more memory might help you gain help.

 

The easiest way is if you know a teenage computer geek at church. They can usually be hired for a soda and a candy bar. They can look at the machine, tell you exactly what you need, install the new RAM, and have a blast doing it.

As exscentric posted though, if you just started having memory issues, your machine may be bogged down by spyware. But the same computer geek should be able to help you with that also, for about the same price.

 

I am one of those church geeks. rdwhite's advice is good. It encompasses exscentric's by leting someone else do it for you.

If your computer is fairly new it will use DDR2, which is still fairly cheap.
