Wow we got people taking pictures and all sorts now lol! There's a button called "pause break" on your keyboard, if you hit it when it the error comes up, the screen will stay at that point/pause
If you're really struggling though do you know how to get into event viewer? In Event Viewe look in system and application and then copy and paste any errors (ones in red) and put them in here.
I'm sorry to say Daddar that leaving a machine off for 5 minutes doesn't do anything. At best it might release a small amount of static charge from the screen?
Get that info to me anyway and I'll tell you what's best to do. Format and reinstalling is always good to do every so often with a machine, but if it's not needed then we wont get you doing it.
