Michelle,

>Am I reading correctly that one bank of memory runs at 100 Mhz and a second at 133? I'd get those in balance and, quite candidly, I'd get the memory from the same manufacturer. All electronic parts are 'made to spec' but all electronic parts are not equal. <g>

>Yes, you're reading that correctly. :) "They" say that the 133 memory will just run at 100 and that everything will be fine. But because I get the problems when I run something memory-intensive, I suspected that may be the problem.

Well, as I understand, the newer computer systems handle this much better than some of the older ones. Is your computer fairly new or have you attempted to upgrade an older one?

>Also, from the Windows Run command line you can run 'SFC' which stands for 'System File Checker'. This little tool essentially checks the various versions of programs against their Registry entry's expected version number. It will prompt you to make changes as needed. Make sure you have your CDs handy. I'd recommend that you run this before the SCANREG process (see below).

>>Clean out Temp files. Run Scandisk & Defrag your HD. Check your virtual memory and all the other things everyone else has suggested.

>Thanks, I'll try those tonight.

>If your system is still too slow - reinstall from scratch :(

>The problem isn't the speed, it's that it locks up for 10-30 seconds at a time.

>Thanks for all the suggestions. I'll give them a whirl and see how it goes.
