|Storage space & memory are 2 completely different things. You listed your memory as 1.0GB - that's reasonably good for an XP system. Your storage space (hard drive) is 250GB. If you've installed or downloaded so much crap that you only have 570MB free space (meaning your hard drive is 99.99% full), there's nothing we can do but to tell you to free up some space - delete, uninstall, move files off the hard drive to an external drive or other media, run a cleaning program such as CCleaner, etc. If you've done all that, you should have considerably more free space, but that still has nothing to do with memory.|
If that's not clear, here's a visial:
This is memory
This is storage space
BTW, How much free space do you have since doing the clean up?
