Cursor Jumps from form field to address bar in Dell Laptop

I have the cursor jump problem in my Dell laptop with Vista Home Premium. Granted I have a wireless mouse but when I unplug it the problem of the cursor jumping persists whether I restart the computer or not. It jumps from the form field to the address bar mostly. This appears to be an explorer related problem because the cursor will NOT jump if I'm typing in yahoo messenger or notepad BUT it will jump in firefox etc. In addition, all the icons will flicker on and off (not the monitor setting so please don't bring that up.) If I'm lucky and hit esc they'll stop long enough for me to bring up a program. I work around when it really gets bad by typing in notepad and copying and pasting to the field I'm filling out, sometimes it can even be so bad that it's the address field in a web browser. I have a registry program, I've defragged recently, I have a driver update program. etc. If it's the keyboard then why would the icons on the desktop rapidly blink. It is not the monitor so please don't go into that.

I installed that malwarebyte program and it didn't find any malware whatsoever. Please someone tell me how to fix this jumping cursor.
