The problem has been going on for at least four or five months before I even installed Service Pack 2. The computer has 256 RAM.

Just right-click My Computer and open the properties box to see if the amount of RAM is reported as the full 256Mb, in case the video RAM is inclusive.
I find that 256Mb is too low and would suggest that you put in at least another 256Mb. This will make a world of difference. Whilst you are doing that just make sure that the original RAM module is properly seated by removing and replacing it as that is all too often the simple problem.
Have a read of this .pdf file and then visit the Crucial site. This is very often the cheapest way to improve overall computer performance.

e.g. the ACER Veriton range.
