Hi guys, I've just built a system for my housemate as follows. Phenom II 955 Asus M478TD- M EVO Gigabyte GTX 460 1GB Antec Builder 430W However, I can't get it stable in BF3. After about 15 minutes of playing the game just fine, I get a 'BF3 has stopped working' error and the game crashes. GPU is running at about 70C at full load. Nothing is overclocked (and the GPU ships at Nvidias reference clocks) Now, because it doesn't crash straight away, it makes me think it is either heat build up in the GPU (though 70C doesn't sound too hot to me) or a PSU issue where the GPU isn't being fed enough power (the second 6pin PCIe connector is fed off a 4pin molex cable, which also powers a HDD). What do you lot think it might be.
