I just bought an 8600GT off the forum, got home and installed it into the first PCIE slot. The mobo goes through the POST procedure and then the onboard LED stays on to indicate a VGA error and there's some beeping from the buzzer (& there's no output to the screen). When i pop the card into the 2nd slot (operates at 8x only) everything works fine.

How can i solve this problem? Yes, i know 8x won't bottleneck an 8600GT but i was planning on going xfire next year and i need to know how to get the first slot to operate
 
Ok, it started acting up again. Switched the pc on and i'm back to square one. Tried reseating the card and i'm getting the same results. Any ideas?
 
Might be a dumb question, but how big is your power supply?
Im assuming 16x uses more power than 8x therefore if you are lacking power it will run on 8x but not 16x?

Long beep. Short beep. Short beep. Short beep. that's it, then it seems like it's booting up, except nothing output to screen (mobo has LEDs onboard, the one for the vga stays on. I've reseated it a number of times and still nothing)
 
If you can test that card in another PC it would be helpfull to eliminate the motherboard.

1long, 3short No video card or bad video RAM reseat or replace the video card.

Ok, will try and get another card and see if that works. I doubt it's the card though, if it were, the mobo would beep when it's in the second slot too
 
Yes, i did.

I just tried my mates 4870 in it and still the same story, the 8600 works fine in his pc too. Guess it's the mobo

I think you mean SLI ^^

Did your 9800gx2 die? Otherwise I'd have stuck with that over the 8600. ( also SLI'ing those wouldn't really be worthwhile, rather buy a 5850 or something )

That said, yeah, sounds like it's a mobo issue, see if the pci bracket is maybe a bit loose, could just be a bad contact somewhere that you can solder back or something.

Definately. That sort of problem tends to creep further to other areas of motherboards with time, best to claim warranty asap.. (read next year ).

Sold the GX2 to fund the i7 build. No, xfire. The 8600 is just a backup card. SLI 8600s would be the fail of the decade

The connector is not loose from what i can tell, it seems to be quite firmly on. Idk
