I hate Computers

I really do, for all the good that these things have done for me, finding myself the best woman in the world and making a bunch of new friends, this computer has really frustrated the hell out of me. Last night I downloaded what I was told was a new version of MSN Messenger, to my chagrin, this cause massive failures and MSN to crash upon startup. Multiple removals and reinstallations of MSN Messenger I finally got MSN Messenger working again but now, my webcam the thing that i use the most, the thing that I love having on this computer won't work. Now at this moment, I'm happy I can send and recieve messages, but any attempt to use a webcam completely kills my Computer and causes MSN to crash. If anyone knows something I could do to make everything work again I would love to hear it, because it is incredibly frustrating not having everything work right.
