Monitor enters power save mode on boot up

[kitenleblanc]

Hello, I have a dell XPS 420 using windows 7.  The computer hasn't given me any real problems a few weeks ago it had trouble booting up and went to system restore to fix any issues it may have had.  After that it booted and shut down up perfectly fine with no problems.  It was unplugged a few days ago while I was moving and was plugged back up yesterday when the monitor displayed the "entering power save mode."  I've tried swapping monitors, holding the power button down while the computers unplugged, removing/putting the graphics card back in, and trying different cables.  There are no beeps and the diagnostic lights aren't lit up to show if there are any issues.  You can hear the computer loading to the windows login screen.  The power button lights up blue and the miniview displays welcome and has the slideshow screen.  I tried taking the CMOS battery out and tried booting that way since I was told that it shouldn't keep it from booting up, but I get a message that says system low on voltage and it doesn't start.  I'm not sure if it's a power supply, graphics card, or motherboard issue.  Can a graphics card just go out without warning?  It's only about 2 years old.  Thanks for your help! Here is a list of my system components.

It sounds to me more like a Monitor power saving mode than a failing vid-card...

Have you tried all the monitor buttons to see ? ?

[kitenleblanc]

I tried pushing the buttons on my monitor and the following message came up "there is no signal coming from your computer push a button on monitor to change setting," and then it goes back to entering power save mode.  I changed the setting from auto select to vga, but still got the same message.  The video card starts off loud, but quiets down as the computer boots up like it normally did.

Try reseatting again video card, cables/power cables.

It was unplugged a few days ago while I was moving and was plugged back up yesterday when the monitor displayed the "entering power save mode."  I've tried swapping monitors, holding the power button down while the computers unplugged, removing/putting the graphics card back in, and trying different cables.

I removed the video card and put it back in and the memory sticks as well monitor still going to power save mode.

Does the monitor do the same thing on another PC ? ?

[kitenleblanc]

Nope, works fine when connected to my laptop.   Ive also tried hooking a different monitor to my xps and it says entering power save mode.

What does the onboard video do ? ?
It's sounding more and more like the card now...

[kitenleblanc]

There isn't a connection for me to hook up monitor to the onboard video.  My other computer has a vga connection to the graphics card and one to the onboard graphics, but my xps only has the one to the graphics card.

Hi

That great thing about owning a Dell is that there is plenty of diagnostic tools built in. First check the diagnostic LEDs the numbers on the front of the computer. Are any lit, if so whats the number.

This will tell me what component is failed or not connected properly

The problem is not exactly on the monitor because it works on your laptop. It could be on your BIOS setting boot mode configuration. Another problem could be on your PSU because it might not be supplying enough amount of power to your monitor so the monitor adjusts itself to power saving mode.
