I'm about to trash this laptop right now..

Now in my list of cultivated problems, I bring you a new one. The damn trackpad isn't working. It was working last night before the drivers for it were even installed. (Yep, worked fine) Now, today, my bro was using it, and he was doing something and he gave it back to me saying that the mouse wasn't working. double you tee eff! ? ! So, I thought it was those one in a while freezes. But no, its not. I restart, and the mouse is still frozen. So, I get aggravated because everytime my bro is around/uses this laptop, he always hits it, or does some spoon, and says there's a problem with it and he didn't do nothing.

I did a repair install of XP, and then took the time out of my life, and that didn't work either. However, I now have a fresh SP2 RTM install. (hehe)

So, I gave the laptop a long rest, and did some stuff around the house. When I go, the trackpad still didn't work. Went online and did a driver install. Reboot, and still no go.

So what now? Please tell me its something stupid and not a hardware phail. Cause, I'm going to be in some deep spoon in my cousin on why the trackpad isn't working. (Ironically, it's the same reason he gave it to me in the first place) >_>

Imma going to see if the mouse works in Ubuntu. If not, idk... And no USB Mouse so I can't have the joy of point and click in the meanwhile. By the way, slide and tap wins anyways.

Ideas before I lose it?
