Actually I'm creating this topic in order to ask a quesiton about one of my problems with my PC but I thought turning the name of topic into Computer, Play Station and such things may make it more useful.

I had a programm called SPSS (may be some of you know it, something like Excel) in my PC. After my job is done with that I wanted to erase it but I think I couldn't make it properly and now every 5 seconds a window named "Windows Installer" appears and interrupts me.

It's sooo annoying. I think I must format C:, anyway I wanted to ask you guys if you knew any other way to fix this s-ht.
