It's a miracle I'm able to post this even!
After the day it refused to work it, it seemed to work fine, but when I can back from my father's B-day party it refused to work again...
This time it refused to even enter Windows XP, sometimes it didn't even get past the first screen!
I cleaned it again and after a few tries I managed to enter Windows, and though all would be okay, but when I tried to open Mirc it simply didn't!
Everything is so slow, the defrag program opened now 10 mintues after I managed to click on it, and it even slows down when I type too fast!
