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.
