I sometimes have this prolbem that if your computer has some serious accident that your booting file was lost, and the computer will not open it normally
Your case that I think:
You should borrow your friends computer's booting and system file
make a copy in their computer
When you opened your computer, you can press f8 to safe mode
and press normal safe mode ,and then you can login in your windows safety
and you must paste the copy file in your system or notebook
Finally ,you can also boot it normal
But if this way can not do it , I think your computer have problem of hardware
You should find a expert to recover it
I think I can help you ^ ^

我都曾經係咁樣,,,
我之後先發現係主機問題,,,
不過教你之前, 我想問下你你部電腦係唔係入碟開呀?!
如果係既,,, 我覺得係隻碟問題囉,
如果你成日關大制既話, 部電腦既資料會好易冇哂囉,
o個時又要重新搞過哂d資料就唔好啦....
我見議你睇下電腦o個d線睇下有冇問題,,,
不過要小心d呀,,,,
不過最好呢,,, 就用d錢搵專家幫你整,
安全第1呀,,,
**希望我地資料幫到你啦^^
