How to fix my computer
It made me
peachy 
"computer was noisy as hell, and parts were obsolete."
How I did it: The fan on my video card was loose and consequently ridiculously loud. I replaced my noisy/old Nvidia Geforce 7600gs with Geforce 9800GX2 - tasty. I also needed a new power supply to support the beastly card. I'm broke, but content.
Lessons & tips: Shop around, and don't hesitate to import! The same card can be three hundred dollars more expensive if you buy it from the wrong supplier.
