OK, so I just added more memory to my PC (thanks Guru. While I was installing I couldn't help but be overwhelmed by the amount of dust in my computer tower. This can't be any good for the system.
So the question is, can I clean this the same way I clean my keyboard and use a pressurized air can? Or should I have this done professionally?
Yeah, it should, but we don't live in Shouldland! Ah, Shouldland, where clean-cut kids cruise Shouldland Boulevard, and the Shouldland High football team gets their optimistic asses kicked by their crosstown rival, Reality Check Tech.
I use cans of air (just bought two today for that purpose, in fact) and they've always worked quite well. Just watch what you're spraying and get in and get out before the can starts wanting to freeze things.
I've seen neat little low-power vacuums for PCs that are even better, but they're probably not worth the money for such a limited use.
Some sites freeze my Firefox. Only in those cases, when I close the window, I have to go to the task manager to kill it off completely. But if I close the window normally (not because of a freeze), I dont have this problem.
