DELL Precision 650 turns on, but shows no signal in monitor?
I have DELL Precision 650 Workstation, and when I turn it on it starts up, but shows "no signal" in monitor. The monitor LED becomes green for 5 seconds and then goes yellow. I have tried to change the video card from another Dell Precision 650, changed the cables, monitors, and even processor, but still couldn't resolve the problem. Could someone help me out with this issue?
I would appreciate any help.
Thank you in advance.

Yeep, each machine has its own authenticated license for XP Pro. Until I have the time to do a clean load, are you aware of a way to make the Xeon processor load to work on a non xeon processor?
Also, do you think I should swap out the processors to see if it is the processor? Is there a high risk of damaging the processor? Can you think of any other options?
What you think about buying another motherboard? Are you aware of any issues with the P650's as they age that would make this a bad idea? I saw some stuff about capacitors and I noticed on another one of my machines some reddish stuff on the top of several capacitors?

Don't know any specific problem history for the P650 but bulging or leaking capacitors are never a good sign. Did you check the motherboard on the problem system?
As for swapping processors, it depends on how careful/adept you are. One bent or broken pin... [:'(]
Doubt there's a way short of a clean install to get this HDD to work on a non-Xenon system.
If you buy a replacement motherboard, be sure to buy from reputable source with some sort of warranty. And if the new board doesn't fix it...?
There's a P650 motherboard for dual Xenon processors here for $255. Only you can decide how much time/money you want to invest into fixing this system vs getting a new system.

Thanks!
The mother board of the non-working system does not appear to have any visible problems.
Is there a way to see if slot 4 is bad. My impression from what you have been saying previously is that Slot 4 is the first one to load. If you loaded 1 and 2, would that yield anything? Is there a way to eliminate having a problem with the actual slots?

In addition to above, here is info on the beeps
1-2-3 = DMA page register read/write failure
Solid green and a beep code during POST = A problem was detected while the BIOS was
executing.
A and B are yellow, C and D are green.
Any other thoughts

I only know what the manual says, and it says to test individual RAM modules in slot 4. So if you test in any other slot and it fails, I don't know if that means the motherboard is toast or if it's just not made to boot when slot 4 is empty.
As for the beep code, if clearing BIOS doesn't clear the error, then it's entirely possible the motherboard has indeed failed.

Hi, I am having the same problem. I have tried different memory cards and nothing.. I had access to several video cards out of retired machines and tried 4 of them. The third one made the monitor come on but with strange lines then, on the forth it started normal. The machine is working fine now but seems slower to boot than before. I'm not sure if it was the card or jostling thins around inside but, I don't really trust that it will be good to go. I may buy a new different video card if the problem comes up again.

You didn't say what model PC you have or what version of Windows, so it's hard to know how to help you. Next time start your own thread and be sure to include this essential info.
But, if you swapped video cards, did you remove the old video driver and install the latest one that's compatible with the working card and the version of Windows?

I think if you follow the differential steps that Ron gave on my issue and are unsuccessful you can feel confident that the mother board is bad. Mine worked for a while like yours is working now, but in 3 Mos it would not boot at all. You should plan for this contingency esp if you are using it in a business environment. The best way to test is using equipment from an identical machine that way you know the part works and should work without changing drivers or the setup you have now. If you have dissimilar hardware you should image your drive before making any changes. If you find any other solutions post it here so I can also try them. Good Luck!
Best, Dr.B
