Here is the support site for the
HP Pavilion a342n desktop.
You should add and save this site in your browser favorites/bookmarks list so you can readily refer to it when needed.
That desktop came with a 512 MB DDR PC2700(DDR333) module of RAM in one slot and has the other slot empty.
That desktop supports a maximum of 1024 MB of RAM, so you need to add another 512 MB module to the empty slot.

Once those 2 temp folders appear and you can view their contents, select and delete EVERYTHING that's inside them.
If a few files resist being deleted, that's normal behavior. Leave them alone and delete EVERYTHING else.
If a massive number of files are being deleted, the computer may appear to "hang". Be patient and wait for the deletion process to finish.
After it's done, restart the computer.
