Need help with display problem

[hardhead11]

I recently built an 1155 system. My new monitor (Samsung 2494sw) worked for a couple of days before I began having issues. I will get a display when I boot the PC, but it goes black a few seconds after the post screen comes up. If I touch the OSD or Auto button, the display will show for a few seconds before going black. I was convinced it was the monitor, because I tried a different video card and the old monitor still works fine.

As a final test, when I plugged the new Samsung into a different computer, it seems to work fine. I'm stumped.

Any ideas or has anyone experienced this?

THANKS!!

Nevermind... It just started going black on the other PC. Sound like the monitor? I'm sending it back.
