This means that the 4 models you have started have all crashed.

Apart from the possiblity of a faulty data set, there are also things like overheating computer, a clash with other running programs, a power supply that is bare minimum for an \'off the self\' computer, your Anti Virus program, etc.

Starting with overheating, you could open up the case and blow out all the dust with a vacuum cleaner, especially the cpu heatsink. Lots of dust on/in this can raise the cpu temperature 10-20 degrees, causing it to get erratic.

Which AV are you using?
Are your graphics card drivers up to date?

More ideas when we hear back from you.
