I have a strange problem. Every once in a while, both in PES 6 and 2008, I lose the connection between my monitor and my GPU, and the screen goes black (says check connection or something). This happens both with my regular monitor; the Samsung Syncmaster 226BW, and another computer's Acer 17" LCD. Now, my CPU (Interl Core 2 Quad Q6600) runs really hot, and I've been told that this could cause it, and I've also ordered a new heat sink and fan. But when I went to my retailer to complain, they said the issue is in the graphics card, and there's something that prevents the GPU and the game engine from working together. This seems likely as PES is the only thing I've experienced this in. They recommended me to try a new driver, and check if anyone else has got this problem. I've got a (pre overclocked) MSI GeForce 8800GTX, with the latest NVidia driver (163.39), but it also happened with an old beta driver (one that Bioshock said I should use as the previous didn't work with Bioshock, apparently. I can't remember if I had the black screen with that driver though). Basically what happens is that randomly in the game (in the beginning it was usually in the second game in a row, but later on it has been the first and even the menu, for example as I'm changing my lineup), the screen goes black, but you can still hear the sounds. (Quickly pause the game so that you won't get scored on. ) Sometimes it comes back immediately, sometimes after a while; I once had to wait half an hour! Oddly enough removing/putting the backcover of my monitor back on seems to make the game come back... So I was wondering if anyone else had this super annoying problem, that I can't seem to fix. It's especially annoying as PES is the game I play most. Next I'm going to ask for help from Nvidia.
