monitor goes black, then displays at about five second intervals. No boot up is shown. It used to show XFS logo, esata detected, press F1 to continue F2 to enter setup(bios) . Now, straight to windows password with lots of black/display shown fluttering before and after password. Flashed bios, loaded latest drivers, no new for monitor. Samsung T220 came with DVI-I single and nForce(2-SLI) GTX 275 by BFG has DVI-D dual. Articles say dual will support single link. Oredered "better" cord on gamble. DVI-D. Used Nvidia control panel to Synchronize Mirrored Array. Checked all seatings on RAM, GPU, power to GPUs. Checked all connections. Corsair PSU. Once the windows key is depresssed, or enter or both, just messing around in general, and a few minutes elapses--all is well and Win 7 64 is magnificent! Temperature? Maybe it needs to warm up or something. CPUID says all is cool as a cucumber.
