P to P software is the bit torrent, and similar programs for downloading illegal songs, programs, movies, and such. But if you really did not know what it was then you don't have to worry about downloading bad software from it.
I forgot you said it's a laptop so i would discount the eject button one.
If your running Vista just type in msconfig in the search box at the bottom after clicking the start button. Then hit the enter key to get the UAC window to allow you to go to msconfig. I doubt you need to do this if you do not download with Person to Person software. But it also does not hurt to know what programs are in the startup and processes tabs, so you can spot it when websites try installing software on your computer.
I still think it is a program causing this problem. I just had a games website install all kinds of crap software on my computer when i tried a trial version of a game. I'll never have anything to do with the Iwin game software ever again.
