No output from graphics card.

July 11, 2012 at 14:58:38
Specs: Windows XP, 3.10 gigahertz AMD Athlon 64 X2 Dual Core/2 gigsx2
Suddenly there is no output from nvidia 9500GT graphics card on Asus M2N68 m/board with 2x2gb memory sticks and 500w PSU. Updating drivers made no difference. When I swap the graphics cards between 2 computers both work perfectly. The other card is an nvidia 6800 and m/board an Asus A8N-E. Any thoughts would be greatly appreciated.

Your power supply could be going. If it is putting out less power on the 12 Volt rail(s) than it had been, especially if it's power was marginal already for the card, it may not be fully powering it now.
Try swapping back the graphics cards and then swapping in the other power supply that is working in it from the other machine. If this works, you just need a new power supply.
Purchase one with a single 12 Volt rail, 80% or better efficiency, active PFC, and a quality name brand.

You have to be a little bit crazy to keep you from going insane.

You're not clear on results of 'swapping the cards'. Are you saying that when you swap in a different card on the Asus the other card works--or does no video card work with it?

Thanks for your response.
The 9500GT card works in the A8N-E m/board, but now not in the M2N68 board in my main computer. When the nvidia 6800 card from the other computer is inserted in the M2N68 board it works perfectly.

this points out 90 % that a power supply could not be powering up the 9500GT,
but the gfx card is powered by the 75W pci-e.
swap in another psu and see what happens

I was thinking a power issue myself, but I think the difference between the 6800 & 9500 GT is minimal. It really depends on the card. If the 6800 is a GT, GS or Ultra, it likely uses more power that the 9500 GT. If it's the plain vanilla version, it's uses about the same or less.

Thanks to all who responded to my problem. It looks as though I need to try another PSU - a post holiday project!

Further update.
I took the PSU from computer 2, in which the nVidia 9500GT graphics card worked, and put it into computer 1. As before, the 8600 card worked normally but once again there was no output from the 9500GT. Doesn't seem to be a power issue.
Baffled!!

With the 9500GT on the M2N68: Does anything at all show on the screen prior to windows loading? Can you boot to safe mode? If so, the resolution set in the OS on the M2N68 may not be compatible or there may be a fault with the card at that resolution.

Do both cards use the same slot on the M2N68?

Thanks for your response.

With the 9500GT on the M2N68 nothing shows at all and the screen remains black. I can boot to safe mode from configsys/boot.ini but the screen stays black. Both cards use the same PCI-E slot on the M2N68.

When you say you can boot to safe mode do you mean you know which keys to use (since nothing is on the screen) and can hear windows loading? Can you tell if it boots to windows in normal mode?

And you're using the same monitor with both cards and verify it's connected tightly to the card?

OK, it's not a power supply problem, it's not a resolution problem (since there's no video when you boot to safe mode), the slot is OK since another card works in it, the card works with another motherboard so it should be OK. . . I don't know. Barring a connection problem with the monitor I can't think of any reason it should act that way. You may have to beat it to death with a hammer and then buy new one.

If Safe Mode is enabled in the Boot.ini menu in msconfig with the alternative graphics card installed, when I replace the 9500GT, I can boot the computer using the keyboard even though I cannot see anything on the screen and I can hear windows loading. It also boots in normal mode. I use the same monitor with both cards and have checked cable and connections on every occasion I change cards.
I can feel the hammer treatment approaching!
