9800 gtx problems

[Jen]

Yesterday i shut down machine as I always do and when i went to restart the computer it failed on video signal fan speed went very high on video card . Thinking somehow bios was hung up i cleared bios and still no video signal. So i tried memory and other things till finally i tried another video card I have here as a spare. I tried my X800 gto i have here which gave me video signal and all is working well that I can see. I then tried the 9800 gtx in another machine which has the same card in it and it posted fine. So then i tried that 9800 gtx from other machine in the abit board and it failed to post. So I dont know what is going on with between this card and machine i am trying to use it in. I will list the system specs I have for this system maybe someone has had this happen to them before and will know where the problem is


Abit IP35-E
2x1 Pc6400 ballistix
9800 gtx
Pcpower & Cooling 510 watt , older powersupply but never has given any problems
Watercooling also used , 12 volt pump
SCSI hard drive for main OS
640 gb sata drive
dvd burner
coolermaster case


any suggestions?

The 9800 GTX needs two PCIe plugs while the x800 GTO needs only one. Are you using any adaptors on the 9800 GTX? If so, try another adaptor, or try connecting the adaptor to some other molex connectors, or try pressing on the adaptor at an angle while powering on your system.

I with Zap on this - not getting power to the PCIe12V plugs 9800's need. Test w/ your tongue- 12 volts won't hurt. JK get a multimeter and test

I'm not as concerned with voltages as much as concerned with the adaptors not fitting snugly enough to make proper contact. Some cards are more finicky than others in this regard. For instance, GTX 280 cards are really picky with their 8 pin connector. When using an adaptor, sometimes just touching the adaptor (not even moving it) will get the card to fail (power LED on card turns red and no picture).
