Hung applications and slow response time using Vista OS
I'm having problems with hung applications (Word, Excel, etc.) and VERY SLOW response times. Dell Inspiron M1330 with Intel Dual Core 1.50 GHz processor, 2038 MB RAM, and Windows Vista Business OS. I removed all programs from the Start menu that I don't really use. Sometimes I click on a file (Word, Excel, etc.) to open and I get an error message that the OS doesn't see the file. I can open the app and then use "open" to access the file but it's a pain. Are there other other settings that I can change in order to improve the situation?
