Hello, I'm posting on my laptop at the moment. Today I was cleaning out my old computer, the whole place was caked with dust. I used a can of compressed air to blow things out and a central vac in the general vicinity of the computer to suck in the dust that were blown out. The problem I'm experiencing right now is two folds. I distinctively remember being able to power up my computer and boot into Windows XP normally afterwards. However there were a series of power failures in my community and I had to undergo reboot a few times. Now the problem is that my computer is booting up extremely slowly. It took over 20+ minutes to get pass the Windows XP loading bar screen. Waiting for my desktop to load took an equally long time to get there. I noticed that even my mouse cursor has delayed movement, it jumps and skips as well. What happened? Was it my cleaning? Was it the power failures? Is the damage permanent? What's going on?
