gahhh all i want is msn.

okay, i officially want regular msn back. i thought i could handle this e-messenger deal, but it just doesn't satisfy the same way. any computer pros out there think they can help me fix my machine?

THE problem: i can't install anything new on my computer because it says there is an installation already in progress.

MY problem: i have no idea what it's talking about.

the COMPUTER'S problem: it has a mind of its own and won't tell me what it's installing and why this alleged installation has been going on for over six months.

suggestions anyone?
