Time to upgrade

Damn..lately my pc is giving me some problems. First the display is showing those very weird colours out. That time I changed the graphics card's fan and was working fine. But now the problem is back again. Second, pc always kena blue screen error. Hmmm, not too sure whether it's the graphics card problem that caused it to be like that. Third, I think my pc is too big..hahaha..time to buy those mini casing liao. With the launch of Microsoft Vista next year. It's a good time to upgrade my pc liao. Buy faster CPU, memory and bigger HDDs for my increasing photos. Guess have to wait for my bonus liao (if there is).
