This is a new build.
The system boots fine, OS loads, Monitor Displays OK with on board VGA video.
Ran ASUS Diagnostics/stress test; all components pass.

Installed single ASUS GTX660-DC2O-2GD5
Loaded drivers and GPUTweak.
Connected Monitor to correct I/O on new card.

Upon reboot, Widows splash screen, then black screen with "no signal" message

Tried downloaded drivers from Asus, Nvidia, and Windows device manager; same problem

This is to be an SLI build, so I switched the GPU card with the second card.

GPU installed in PCIe slot 1

Same problem, no signal

Tried the SLI bridge with cards in PCIe slot 1 and 2 , same problem

Bios 2104 is running at default except Ai overclock tuner is set to X.M.P., switching back to "auto" doesn't help.

GPU driver is 314.22WHQL

I started over with a fresh install of the OS, the Asus motherboard CD and the GPU CD

Boots to Windows splash, goes black, "no signal" message

I even tried a different monitor thinking that a refresh rate conflict might be the problem.

Still "no signal"

Also, replaced the power supply, no help
Ran an “out of the case” trial, no help

Please advise

Please help

With the standard vga onboard video all is well
The no signal problem happens ONLY when the Asus GPU card is installed with the Asus/Nvidia/Windows driver
thanks

SOLVED

Thanks for all of the suggestions

There was a driver conflict with the onboard video and the Nvidia GTX

I DISABLED, not deleted, the onboard video driver in Device Manager

Then I installed the Nvidia driver.

Now I have a sweet SLI setup running!

CAUTION: Windows Update will download drivers for the onboard video even though it is disabled. DO NOT install them, easily done if you mass apply your updates without checking what each one does

that sucks, I have the same issue but I have the asus R5E mobo and there is no onboard graphics but it is acting as though it has multiple screens attached or something and gives me 'no signal'

To cut a long story short it was the refresh rate.
The driver selects the native resolution at 60hz as soon as it installed.
My tv supposedly supports 60hz but would only work when I plugged in another monitor and turned the tv down to 30hz.
