Dell Inspiron/no display

My daughter has a Dell Inspiron 2500. A few months ago, the monitor (an LG) started not working intermitently. I switched it out with one that I was using (a Sylvania) and it worked fine, and the LG worked with my computer.

Fast forward a few months, and now neither monitor works with that computer. But the LG works on my computer; the Sylvania doesn't. I got a new video card for daughter's computer, thinking it was that. Could it be the monitor? As I said, my working monitor did not work with that computer. Might it be something on the motherboard and if it is, can it be fixed?

I should add that when I turn on the computer with monitor, the monitor flashes the "no display" signal, then goes black again.
 
Sounds like the onboard video died....but thats very bad! It's bad because you have to go into the Bios to switch sending the signal to the PCIe slots for the discreet video card to work! But obviously, you can't see the screen to get into the Bios to switch it over for the video card to work.

That sucks man, it needs a new motherboard.

The only thing maybe that you could try, not sure if it would work, but a USB display adapter *may* work. But the issue is they are pretty much as expensive as a new motherboard plus it may not even work.

Thanks for confirming what I suspected....I think rather than sink money into this old thing, I'll get another used one for the kids to use...

This is not correct! You do NOT have to enter the bios to switch it to pci-e. Just take the side panel off, pop the card in, and boot up. The mobo will automatically switch the power over. It might be different on real old machines.

I've had several that don't switch over just putting the card in....including BRAND NEW builds. Had no display output from the card, so I stuck the monitor cable on the onboard video and bam the picture was there. Had to change it over in the bios off the onboard. This has happened to me atleast twice, maybe 3 times.
 
No I mean changing bios settings. He's saying that just putting in the graphics card it automatically should run from the card. However, I've had a few builds that wouldn't and still ran off the onboard GFX even after I put the card in. I had to enter the bios and change some settings so it would run off the card and not the onboard, but you can't do that because your onboard has no output! Follow all that? lol
