several issues
ALSO DESKTOP X MAKES MY PC RUN SLOW.. PRESUMABLY B/C OF RAM (?).. I HAVE 604MB ( I THINK). ASIDE FROM NOT USING DESKTOP X OR BUYING MORE RAM (WHICH IS NOT AN OPTION) IS THERE ANYTHING I CAN DO TO MAKE MY PC FASTER WITH DESKTOP X?
Noboday said/thought you were dumb, Blonde37 ....in fact, these were genuine, helpful and though-out answers/assistance that members here provided to your questions..
With the minimal amount of ram you have ...it's quite possible you DO have too many processes running... 
I'd try closing DX objects one at a time to see if one of those is causing a slowdown. Some objects operate in real time and can use a lot of either cpu, ram or both.
There are many routes to follow when trying to diagnose a problem. Kicking-off at those trying to help is not likely to bring many answers
BLOND37 ...when you're asking a question/for assistance the trick is to expect you will receive advice/assistance.
The quality/suitability of the assistance will work on the GIGO principle. If/when people are required to assume/guess what system specs and/or computer experience you have you may get the impression people my think you are naive or a novice.
Your question is 'how do I make my computer run faster/better with DesktopX?'
The answer will be - optimize your system, eg, defrag/cleaning/memory upgrades/etc., and not necessarily 'press button 'X' on the left side of a proggy for an instant speed-boost'.
Generally speaking all systems will be slowed by what is currently loaded/running....so the answer for you is much the same as for any other program.
First you need to document all your relevant system specs, not just ram and CPU. You 'may' be suffering some actual program incompatibility/conflict that is bogging things down [I know I do....often]...
