With some ATI cards (9600 and 9800), Spring reboots after some minutes.
If you have an ATI and an Asus mobo, its maybe, a solution to follow my advices:
Get a more powerful power-supply if you haven't, and update your mobo BIOS.
I have an Asus A7V600 X, and it seems it has compatibility problem with 9600 on 3DMark, and makes the computer reboots (same as spring).
So, i tried to update the Bios, and to be sure, i disabled the Fastwrite in the bios. And now, Spring works correctly (I played more than 1h20 with no crash.).
Sorry If this solution has ever been proposed, but this topic is easier to find, and the answer is here, and you don't have to search in an other, with very much messages ect...
Sorry for my bad English too ^^. And good luck
