Well, the problem was solved a few days ago and now my computer works fine again. It was actually much simpler problem than me or my big brother thought. The problem wasn't a hard drive breaking up or a virus. It was an important cable that was too loose from its hard drive (where my Windows was... and still is), which actually explains why the computer froze up nearly everytime during Windows installation when it scanned that hard drive. I feel a bit stupid now. I formatted those two drives for nothing.

That's not all, though. My dad was shocked to find out that my RAM memory was only 512 Mb in total even though I had 2 chips in place and wondered how in the world had my computer managed to run fine this far. I wasn't surprised because I knew those chips were never replaced. They came from my original computer. Anyhow, my dad went and bought a 1 Gb chip that fitted for my computer (my motherboard is a bit old and supports only DDR chips), so now my computer has 1,5 Gb RAM memory. Also it seems my dad bought a new wireless mouse only because the old one's wheel didn't work properly. A bit of waste of money and 1 USB port IMO.

... I feel so guilty actually. My dad buying an expensive RAM chip and a wireless mouse. My mom buying new flowers for my yard... and both of them buying an extra shelf, wine glasses and a new wide flat HD TV. I feel so guilty because they've bought all that stuff for me. Exactly what have I done to deserve this, besides passing all the school courses so far? Nothing. I can't even be a good host for them and offer a nice bed when they come to my place for a night (I do have an extra bed but apparently it's not comfortable to sleep in) or cook for them. My mom said not so long ago that this is because I have never asked for any money from them or even spent much money for anything extra, because I've saved up most of them. *sighs* I think they have too high hopes for me.
