I have noticed a little problem that sometimes happens.

For some reason, Windows 7 will sometimes not recognise my graphics cards and disables the devices. This means, I have to go into device manager and re-enable them.

Is there something I am doing wrong? I have set the values in the bios for vdimm vccio etc as per andressergio advice and I have reinstalled Windows 7 with Service Pack 1.

I have run Intel burn test and my system is stable and I have upgraded my bios to 2001.

Any thoughts?

Regards,
