2 issue No video on boot & HD priority change

Evga Geforce gts 250 video card - 512mb...

Specs: Win7 x64, Q6600 / 4GB
Two problems:

(1) No video signal to the monitor during bootup. The screen doesn't turn on until windows 7 is on the 'starting up' screen. If I use another monitor there is a 50/50 chance of there being a video signal. Sometimes restarting the computer 5 or 6 times will somehow get the monitor to display.

Which leads me to my second problem..

(2) When the computer is restarted several times during the initial startup, the harddrive boot priority changes. Then I can't change it back because my monitor doesn't display during bootup.

Information on the model and type of computer would help. If boot options are changing then the CMOS battery is probably weak or dead. The lack of video at start up requires more info.

I was able to get the monitor working by plugging it into the second DVI slot on the video card. It was detecting as the secondary monitor during boot even though there was no other monitor plugged in.

I'm running a 3-4 year old motherboard and the CMOS battery is a good idea. I just found that the HD priority change is actually a full BIOS setting reset. The motherboard is an eVGA 680i LT SLI.

My next steps will be updating the BIOS version and getting a new CMOS battery.

I do have one other weird, phantom sort of issue. Which is, while the computer is powered down and the monitor is turned off, the monitor will turn itself on randomly 2-3 hours after it was shut off. Very strange.

edit: Monitor is a Viewsonic VX2835WM

You evidently are not shutting down but placing the computer in one of the suspend modes. If that is not happening then someone may be remotely accessing the system.

No, the computer is off. I'm starting to think there might be a problem with the monitor's power supply or the power cable. Sometimes the monitor doesn't turn on unless the power cable is unplugged/replugged, or the powerstrip is reset.

So, you are shutting off power to your computer by switching off at a power strip? If so, why isn't the monitor plugged in there too?
