Reuse RAM 204
"Too slow" is way too vague a problem description. It could be memory issues, hardware issues, application issues -- or it could be that you've got a few dozen (or more) spyware-adware programs hogging system resources, and probably spewing your personal info to God knows who.
The FIRST thing I do when I get a complaint of "slow system" is to install, update, and run SpyBot Search & Destroy and AdAware Pro. Then, after cleaning up anything they detect, I see how slow (or not) the system still is.
I would suggest doing the same.
If that's the case, I don't see any reason they wouldn't work. However, I cannot say for sure without examining the specs myself.
As for where to buy extra memory, Crucial or other reputable third-party suppliers seem to do just fine. No need to pay Dell's inflated prices.
Keep the peace(es).

I have a Dim4600, so you are probably using WinXP on it. You should have at least 512 MB of RAM...
