I just installed a new Hewlett Packard Deskjet 842c printer on my computer and now my computer is responding extremely slow. Sometimes the mouse moves across the screen slowly or choppily, when typin in word or anything else the letters appear slowly, and my internet connection is operating slow. Everthing is just moving slower than normal, and it all started right after i installed my new printer. I've got 5 gigabytes of memory, and 64 megabytes ram so i don't think its a memory problem. I don't know what to do and my computer is running so slow its difficult to even write this email. My clock is even running slow. Please help.
