Hello,

First time poster here, just had a quick question. Bought a gtx260 55nm from newegg. When the card came in I installed it and made sure that my PSU can support it. My psu is Antec 650w with three 12v rails at 25a each. The problem I ran into is when I install the drivers Vista reboots and right before the login, the screen goes black and just sits there... forever :confused:

I also tried it with windows XP and during the driver install the screen goes black and never comes back. The card works, as in it displays stuff in VGA mode, as soon as I install the driver it freezes. Now that leads me to believe the card is bad, because I tried different drivers and it does the same thing. I am getting a replacement tomorrow, thank god I bought it at newegg, but I'm just wondering if it could be something else other then a bad card. Any input will be appreciated.

Thanks
 
Try using one of the other 6 pin pci-e connectors to see if using a different rail helps.
Try re-seating the card.
Only other thing I can think of is an edid issue. What monitor are you using? You might try setting it to use a lower resolution before you install the drivers and see if that brings it up then adjust resolution to your monitors native.

idk.........weird one. :confused:
 
Thanks

I tried using the other rail... to no avail... hey that rhymes! I also reseated the card but I haven't tried changing the resolution before the driver install though.
 
Well, my first guess would be if the card only screws up after you install the driver, there's something wrong with your driver install. You sure you're downloading the correct driver for your system? If this is a clean install of the OS as well, have you installed the chipset drivers first? If you only switched cards, did you properly uninstall your old video card drivers, driver sweep them, then install the new ones? Sorry for the simple questions, but sometimes people overlook things and this will help in the troubleshooting process :).
 
Done all of that, when the old card was in the computer I uninstalled the old drivers shut down the pc and installed the new card. Downloaded the gtx 260 drivers off of nvidias website installed the new drivers... black screen. The reason I did a new install of the OS was because I thought I did something wrong when installing the drivers... which I don't know how someone could mess up the next next next finish process... but with my luck...

The chipset was updated once I installed the OS. I also tried the drivers that are on the CD with the fresh install of XP and the same thing happened. So I really don't know, it must be a faulty card.

Ohh btw the card is made by EVGA, I haven't called them yet because I am still at work.
 
I will be interested in seeing what the new card does... Even though your PSU should have plenty of amps for that card if the problem continues with the new card I would think that its not working like it should. If I understand this correctly, the video card isn't really drawing any power to speak of in VGA mode, is basically a pass-through (someone correct me if I'm wrong) and once you get your drivers installed the video card starts pulling some amps to function normally.

I have had several Antec PSU and never had a problem with them, but lots of people have.
 
what Antec 650 watt psu do you have because none of them I have seen have 3 12v rails with 25amps each? I have the Antec Earthwatts 650watt psu and no troubles at all. also on most power supplies they dont really technically have separate 12v rails.

I apologize about the PSU, I have the same PSU as you and I was pulling the numbers from top of my head at work (22, 22, 25 actually). I also thought 12V1 12V2 and 12V3 means three 12V rails, I guess I'm wrong on that too. Hey you learn something new everyday I guess.

Nonetheless the PSU should be plenty for that particular card. I am getting the new one tomorrow and will let you guys know how it turns out. Although I have never seen a video card act like that but we'll see.

well yes it does mean 3 rails according to its listed specs. I am just saying that a lot of times it turns out to actually be technically just one rail.
 
Just got the new card from newegg, and it worked without a hitch. Looks like the first card was a dud. Thanks for all the input guys.
 
My GTX260 55nm EVGA just showed up today. Installed without a hitch. Picked up avg 10FPS over my 8800GTS 512 SLI in Fallout 3 to boot (i'm ditching SLI mobo).

well dont you have a lower end cpu and play at a res below 1680? if so then SLI in a setup like that was never fully useful.

I'm excited to try all the games tonight. Ran home at lunch to install the card to see if it works. Glad I didn't get a second dud :D
 
Jesus I am still having the same problems with the card, now they happen only 50% of the time, where windows won't even boot. I am starting to question the power supply and not the card now. I don't think I can be that lucky where I get 2 bad cads in a row.
