Monitor in Power Save Mode

I have a strange problem with my monitor (Dell P991). This morning when I turned on my computer (custom made: Asus A7V600, AMD 2700+, 2X512 GB Ram, 80GB Seagate HD, ATI 9200 Radeon 128MB) it displayed "monitor in power save mode activate with your computer". I disconnected the video cable, and the monitor self diagnosed OK. The power LED on the motherboard is green. The optical mouse red light does not come on, and I cannot see if the keyboard is detected. Restarting everything did not change the situation. I tried with two other monitors (a Samsung and a DigiView), each with its own signal cable. The Samsung did not display anything, and its on light near the switch kept blinking, as if in a power save mode. The DigiView displayed: "please check the signal cable). I know that these monitors are OK. So, the problem is with the communication between my computer and the monitors. I removed and reseated the video card and the Ram, but nothing changed. What might be the problem, and how should I proceed?

Thanks.

Thanks. I have another video card (Gigabyte GV R7064T - graphics adapter - RADEON 7000 - 64 MB) from an older computer. I replaced the video cards, but the monitor did not come out of the power save mode. I suppose that this video card should work with the MB on the computer. I also checked the monitor with my laptop, and it works fine. Any suggestion on what to do now?
