(vga) monitor displays no signal

Third, clean up the confusion. Did you install a dedicated graphics card? What card, specifically, did you install and is it still installed?

I thought I had asked that...

And still we wait...

OK, from the beginning. I went to Dell Support to update my onboard graphics card. This the support page with all the latest updates. (My PC TAG #4H8S1F1) http://support.dell.com/support/down...iceTag=4H8S1F1. This page gave alist of all updates for my pc. After I downloaded the graphics card I created restore point and then proceeded with install. When it finished the install wizard recommended restarting. After restart I had lost signal to monitor.

I am not sure what the exact name of the download I installed, but if I could get to my files I would tell you. I have put everything back to original condition before I opened case. I have a new PCI Express Card but the manual says that the onboard graphics card needs to be disabled which is sort of a problem since I can't get to Device Manager. I also have a new Power supply (550W PCI-EXPRESS Comenetor 12CM Fan) not yet installed. IF you follow link above it shows you all available updates for my system.

When you (try to) start the computer does it appear to be doing anything? Does the HDD activity light flash and/or can you hear the drive running? What about the fans - are they spinning?

...

Yes all fan are running internal drive starts my mouse even light up and flashes. On startup my mouse before I lost signal would flash when my pc was loading and it still does same thing now. So it sounds and looks like it is loading.

Have you tested the monitor on another computer to make sure it in fact works properly.

Do you have another monitor that you can try, even borrow a monitor from a friend that you know is a good working monitor ?

 

[pcdummy]

Yes i have another monitor one of the old ones that takes up the space of your whole pc desk it displays no signal also...and my LCD flat screen is less than a year old and it was working great till I went to dell support to update my graphics card.

Is the new PCIe graphics card installed or not? If yes which video (VGA) connector is the monitor connected too? You want to be very careful with the motherboard jumpers, especially the clear CMOS jumper. Incorrect placement of that jumper can and has damaged motherboards on power up.

 

[profdlp]

Where were the motherboard jumpers before you returned them to the "normal" position?

 

[pcdummy]

Both jumpers was on 2 & 3

I did have my jumpers in the wrong place, but i lost the display signal after I ran a "Dell Recommended Diagnostics" using PC Checkup in Dell Support Center 3.0 and it said my graphics card needed updated. After istalling the update it starts up lights up sounds like it has always done but my monitor stopped receiving a signal. THAT is when i moved jumpers. I am almost ready draw a BIG target on it and get my Winchester 270 and put a few rounds into it.:devil:

You've got nothing to lose now, I'd put the new video card in, connect the monitor to it, and see if you get video. Some BIOS will auto detect if you have an add-in card installed and switch on their own without having to go in and change a setting. You didn't say which manual said you had to change a setting in the BIOS, I'm guessing it was the manual for the video card. Either way I'd try it at this point, you might get lucky.

I would do the following in this order:

1) Turn the computer off
2) Unplug it
3) Remove the CMOS battery (looks like a watch battery; on the motherboard; note which side is up before you take it out)
4) Move the CMOS jumper back to the 2 & 3 position
5) Wait about ten minutes
6) Move the CMOS jumper back to the "normal" 1 & 2 position
7) Replace the CMOS battery - don't put it in upside down!
8) Plug it back in
9) Pray it works

Make sure you do them in this order, especially the ones I underlined.

If still no luck, you might as well put the new power supply and video card in and hope it works.

EDIT: alphanumeric types faster than I do. He gave you good advice, but I might try the CMOS reset one more time since it's not clear you followed steps #2 and #3 when you did it before.

What happened? You didn't use the Winchester on it, did you?
