Blue Screen

Sometimes, your computer will freeze up and get a Blue Screen saying some Errors. This is called the Blue Screen of Death. It basically tells you that your computer is dying. The computer should then shut down. My advice is to turn the computer back on, and sometimes it will say: Windows has recovered from a serious error. Thats it. Problem solved. If it doesn't, there is most likely a problem with your Hard Drive or something.

My old laptop would get the Blue screen of death when i pressed 'G' slightly too hard... no joke -.-

Restarting it worked for about the first 10 times, but in the end it gave up, and so did I tbh.

But yeah, restarting normally works

Otherwise known as a stop error . It can happen for a number of different reasons (don't go junking your HD chances that thats failed without previous warning are very small).
Thats why there is a code shown on screen.

For a full explanation of these codes go to http://pcsupport.about.com/od/findbyerrormessage/tp/stop_error_list.htm or a similar site.

Simply googling the stop code will usually explain what has happened.
