Clear CMOS

  1. I have an ECS 848P-A7 motherboard and a P4 CPU, and when I boot up the computer, I get sometimes get a message that says:

    "warning CMOS settings have been changed. Press F1 to continue or DEL to enter setup"

    However, I only get the message occasionally. Most of the time I get a blank screen right when I press the power button and my moniter says: "RGB No Input Signal"

    My power supply obviously works since power comes on, RAM is good since I tried it in a different computer, and the video card works since I also tried that in a different computer. I think this is a CMOS setting problem, rather than hardware related. There should be no problem if I clear CMOS by repositioning the jumper on the motherboard, right? Any other suggestions would be welcome. Thanks.

    Clearing the CMOS should reset the BIOS to failsafe values, yes.

    Know its a bit late , but for the benefit of people reading this even now,
    Effects like this are almost always the first sign of a dying motherboard battery.
    Replace it , if you see something like this , they are cheap
