Not Monitor so what is it?

Dell Precison 610 XP pro. Working fine til this morning and it had a "no video signal" message on the monitor. Swapped Monitor, swapped vidio card, swapped cord, I can log on to the box remotely and and devices look fine but still no video. Occasionally video would flicker on for a couple of minutes. Can this be power supply related?

Give me your thoughts...

Thanks

 

Since you've tried all those things, the only thing left is the motherboard. I would try using a PCI video card if you are using AGP now or an AGP video card if you are using a PCI card now. Just to test those slots.

On some mother boards the failure of a video card slot causes a special POST beep code (beep sequence at boot). But since your monitor flickers sometimes the slot might not be totally unusable which could allow your computer to boot without the special POST beep sequence.

Other than that, you could hook the monitor/cord/video card up to another computer just to prove that they are in good working order. This would for sure place the problem with your motherboard or something external to the computer (e.g. super strong magnetic field in the computers room, etc...).

 

Thanks for the reply Training,
I'll try the different video card if I can find one. The monitor is now displaying the windows 'ready for logon' screen consitantly but when you complete the logon, it goes black/no signal?? I had done the complete monitor cable swapping evolutions so I like your 'motherboard' theory.
