Doom3/ crash back to desktop

[Vista]

Probably an old issue already discussed inthere....but does anyone know why Doom3 keeps on crashing after a certain lap of time : no error message, just freeze and then back to desktop (it was nice to see u play, bye and that's it !) ? And how could I have fix this ? The ID D3 patch is already installed...doesn't seem to help very much !

I've had Doom 3 for over a year and beat it many times on 2 different computers, but I've never had that happen to me. What are your system specs??

 

[Vista]

Well, the CP is a Pentium IV 2.40GHz with 512 Mo RAM. The Video card is a 128 DDR ATI RADEON 9800. Normally far enough to play the game but... I really can't fugure what's going on : sometimes I can play for more than an hour without any trouble adn sometimes after just 5 min, the whole systme crashes... desktop, here I am !

Huh, I was thinking your PC didn't meet minimums, but I guess it does. Try downloading the latest drivers for you video card.

The ID D3 patch is already installed.

Just to be explicit ... what version are you running?

What version of catalyst are you running?
