!!!~!~COMPUTER HELP!~!~!!!

Alright, well recently on my other computer I was browsing the web. Sites like myspace, ign, mp3fusion, gamefaqs, when suddenly my power turns off. It turns out that my brother turned of the power switch by accident thinking that no one was upstairs in my room. After that when booting up my computer, it flashed a blue screen and I was able to catch a glimpse of something like "begining dumping of physical memory" or something like that. Afterwards none of my applications will work, let alone even pop up. I tried to run my internet explorer, and that wouldn't even pop up. World of Warcraft wont boot up, realplayer, windows media player. To make things worse I'm getting yelled at for destroying the computer... again... I'd like to bring it to a computer expert but the thing is that I don't have the cash to do that. I'm in dire need of assistance. So please, someone help A.S.A.P.

Thank you all everyone for taking your time to read this and eaid me in my situation.

Jam it back in, in the dark.
