I’m sorry if my little car joke ‘backfired’ (if you’ll pardon the pun) I was merely trying to take the load off of what was becoming a very heavy topic. This my considered reply and I make no apologies for it’s length. Although I am no Techy I have owned and used a computer since 79 or 80 starting with a Commodore Pet.As far as I can I will try to explain in simple terms why computers crash. More analogies I’m afraid. They are basically a collection of circuits and switches, and in the sense I intend here no more complex than your house circuits. Each time you press a key or click the mouse you switch something and usually something else off.If this, then that. Is how it was once explained to me.But you have to understand one fundamental thing “computers are incredibly stupid” If you were to write a series of blissfully simple instructions but, forgot a comma or maybe a full stop and gave them to an idiot, he would almost certainly understand and follow them. However try that with even the most sophisticated Mainframe and it’ll stop dead. Now when you tell a program (PD 13 for example) to do a certain thing ‘turn a light on, let’s say. It has not the least idea why you want to turn the light on, it just does it. Unless you accidentally tell it to do something else, that is. So stop expecting the program to know what you want it to do if you don’t give it the correct instructions! Now for an analogy: We all know that video editing is very computer challenging as is 3D CAD rendering (something I know from my business) If anything is going to crash a system they will.So, imagine your simple electrical circuit at home. I have my dimension saw running at 15KW 415V my thicknesser at 12KW 425V my radial arm saw running at 5KW 415V my vacuum press running at 3KW 240V. I go over to my bench and turn on my Glue pot (a tiny 120W 240V) and bang I trip the disjoncteur. A workshop crash.The disjoncteur is my safety device. I have no wish to set fire to my workshop by overloading the circuits.A computer crashes for exactly the same reason. You do something that could cause it to damage its bits. Burn out the Motherboard for example, and that’s it, no computer. So the nice people at Microsoft build in disjoncteurs to prevent this. A pain in the arse maybe, but a hell of a lot less hassle and money destroying your computer.So next time it crashes stop and thank them for their consideration, and look long and hard at what you did to cause it. It’ll be either you telling it to do something it is not designed to do or you told it in the wrong way.Happy computing.Pete the Wood
