trouble with new build ga x58 ud5 gtx260

[Steve]

when I boot up after being shut off for a period of time the video card will detect as standard video in device manager.At this point the gtx260 cannot be detected and no nvidia drivers will install as they do not match any hardware.If I reboot the card will be detected and the system works perfectly.I have tried reinstalling video drivers several times using various methods and putting the card in a different pcie slot.Nothing has helped.Also if I shut down and reboot 45 minutes later it will still boot properly.The problem only shows up when it has been shut off for a longer period of time.Anyone have an idea,thanks

Just a shot in the dark, but did you try downloading the latest motherboard drivers in case there's a problem with the PCIe interface drivers?

Other than that.... you're going to need to post the rest of your kit for folks to be able to help you out. (PSU, Memory, Case(for cooling), etc....)

The power supply is a antec tripower trio 650 and the ram is G skill 3x 1gb 1333 ddr3.I will try Gigabytes site for motherboard drivers but I think they are still the same versions that shipped with my board.

Running the EXTREME version of that board (same board for all intents & purposes) with a couple of GTX 260s and I haven't encountered anything like that. It might be RMA time. I suspect the video card.

Could a dead motherboard battery cause that?

[Steve]

Wouldn`t a dead battery cause you to loose bios settings in the cmos?

I doubt its the GPU, however, is thier anyone you know that has a PC with a PCI-E slot so that you can test that Card (prior to RMA'ing it). What method do you use for unistalling / installing Video Drivers? As in Clean sweep yada yada yada...
Prior to RMA'ing anything I would tend to try both a OS Repair and /or Clean install of OS.
Then go to next step....

Do a bios flash too.

What Squeetard said.

Try downloading the latest bios and see if that helps. I'm currently using F4k and it's been good. F4l corrupted on my and F4n won't boot at my previously stable settings.

Yesterday i did a complete reinstall of windows,flashed the bios reinstalled video,motherboard and device drivers.I must og rebooted a hundred times and as usuall everything worked perfectly.I got up this morning booted up and standard video adapter reappeared.I shut down and rebooted and my gtx260 detected as usual.I`m thinking this must be hardware as this is my 3rd windows install in a week.
