I have just built the following pc - Vista 32bit, intel core 2 quad(q6600 b3), Sapphire 2600XT 256MB, Antec earthwatts 500w psu, 2GB RAM (corsair twin2X2048-6400 ddr2 800mhz), sataII 160gb with the OS on it, sataII 500gb partioned to 2X 250gb ish, NEC optiarc ad-7170s sata dvd burner. The bios is 2004. I run the sata drives as AHCI drives and i think they are set right in the bios?
Everything boots up ok, i have the latest intel chipset drivers etc. and the pc is very fast etc. as you would expect - this is whilst running on the default vga adaptor.
My problem is after i have loaded the latest ATI catalyst driver set from ATI (Catalyst™ 7.8 Display Driver for Windows Vista (32 bit) the pc boots and soon after vista has loaded it will blue screen. When it's restarted Vista reports a problem with the video driver. Sometimes it will stay stable until i try to take the card from 600x800 res to the correct one and then it fails as before.
As far as i am concerned i have the mobo running correctly i.e.not overclocked or anything.
Can anyone with perhaps a similar setup offer me anything to try?
