Glad to hear it works!
Lots of software will set itself up to load at system startup. This is an unecessary waste of system resources. My personal rule of thumb is: nothing starts with windows (except Anti-Virus software). If I want something to run, I turn it on when I need it and turn it off when I'm done with it. Most software will have an option to have it run or not at wywtem startup. If it doesn't but runs, then use msconfig/startup to turn it off.
Become familiar with your startup list. Other things can put themselves in there also, like spyware and virii. Notice anything new in there, then ask yourself where it came from. Become suspicious if you haven't installed any software.
