EB will not load up

[Dumbass]

Well this is very strange. Upon loading up my computer the next day and loading up EB it works, with all the modded files. Very very weird. It's like EB is choosing randomly when to load and when to crash upon loading.

Also worth noting, there's a tell tale sign of when it fails to load - the computer hardly makes a sound and the rtw box is there for ages, whereas when it succeeds in loading up, the computer whirrs away. It seems more like a problem that my computer just doesn't even try loading anything.

Edit: After playing a long session with a koinon hellanon campaign, I exitted EB. Now I am trying to load it again, but it's not working! I haven't touched any of the files. This must be an issue with my computer, but I have no idea what could be causing it. It's very liekly that when I load it up to play this time tomorrow, it will work. Could it be a problem with over-heating which makes my computer refuse to load up the game until it has had time to cool down?
