Blue screen of death

My computer is now essentially dead. Luckily I have internet access at work and an hour lunch break :D It’s been getting increasingly unstable for the past month or so giving me random blue screens of death. Sometimes I get a driver reference that caused the problem (and they are different drivers each time) and sometimes I don’t. Yesterday it managed to crash while trying to display the Windows log-in screen and I was left with just a cursor on black screen. Since I now have money and it’s old anyway (Athlon 1.2GHz - back when AMD named their processor after their real speed) I’m not so bothered. blue screen
