Windows 7 win 7 64 bit monitor flutter on boot up

[normco]

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.

It seems like you are experiencing a peculiar issue with your monitor and boot process. The symptoms you described, with the monitor going black intermittently before displaying, might be related to the graphics card or the connection between the monitor and the GPU. Here are some steps you can take to troubleshoot and potentially resolve the issue: 1. Check Cables and Connections: - Ensure all cables, particularly the DVI-D cable connecting the monitor to the GTX 275, are securely connected on both ends. - Try using a different cable to rule out any cable-related issues. 2. Monitor and GPU Compatibility: - While DVI-D should be compatible with DVI-I, it's worth verifying that the monitor and GPU are compatible and that the GPU settings are appropriate for the monitor. 3. Graphics Card Drivers: - Confirm that you have the latest drivers installed for your GTX 275 graphics card. Sometimes driver updates can resolve display issues. 4. BIOS Settings: - Check the BIOS settings to ensure that the primary display output is set correctly. It should be set to the graphics card you are using (GTX 275). 5. Temperature and Warm-Up: - Monitor the temperatures of your GPU using tools like CPUID or MSI Afterburner. Ensure that the GPU is not overheating during normal usage. 6. Power Supply: - Since you mentioned using a Corsair PSU, make sure that the power supply is providing stable power to the GPU. Fluctuations in power supply can cause display issues. 7. Testing with Another Monitor: - If possible, try connecting your GTX 275 to a different monitor to see if the issue persists. This will help identify if the problem lies with the monitor or the GPU. 8. Windows Updates: - Ensure that Windows is up to date with the latest updates and patches. Sometimes operating system updates can also address display-related issues. If after performing these steps the issue persists, there may be a deeper hardware problem with either the monitor or the GPU that requires further investigation or professional assistance.
