My Performa 635 CD has recently begun operating very slowly. The CD drive is crawling, a largish Claris Works word processing file takes much longer to launch and to save than it did last week. Even typing in is sluggish. Sometimes text is garbled or doesn't appear. I have reinstalled system 7.5.3 and finder and CD related extensions from my back-up, run Tech Tool to renew desktop with extensions on, and again with them off, and zap PRAM. I disabled a number of extensions when things slowed down-I think the unnecessary ones. I checked for viruses with Disinfectant (3.6 I think) I considered dumping all preferences and the Claris ones that live in a seperate file, but I'm chicken. Can anybody help?
My Mac has 36MB of RAM, disk cache set at 512, 68040 CPU, 250 meg HD that is not full, Zip drive. Thank you in advance
