I can't use floppy at the moment, so I'm going to try and load up the iso onto a CD and do the memtest.
After the Tune Up, and during the Tune Up, I still experienced the same situations of lag and freeze. But I noticed a lot of things that got removed, and nothing has gone wrong yet; so that's a good sign. Even if it doesn't solve my current problem.
Aside from the memory test that I'm working on now, and the things I've done already. Are there any other things I can do to help my computer and solve my freeze lag?
Thanks a lot for the all the help so far, and all the future help.
