Constant bluescreens and slow performance

I have been experiencing constant crashes. Sometimes the computer bluescreens during start up and it almost always crashes when running more than one program or web page.
Please help.

OS is a bootleg version of windows 7 build 7600 which has worked fine for about 2 years
