Ok I just upgraded my inspiron 531's ram from 2 to 4 gigs, installed a new PS http://tinyurl.com/32cpym which is fairly cheap but from the comments at newegg should run the 9800 gtx+ just fine.

Here is the card: http://tinyurl.com/ygt2fod

Now with everything installed I get no video signal. If I put my 8600gt back in the power supply and ram are fine, the signal is fine and it boots up. Im curious why im not getting video signal with the new video card.

The DVI is the same as I used with my 8600gt and the fan on the card is spinning so its definately getting power ... Any ideas? Am I forgetting something?

Thanks

first off, your links are dead. Im assuming the new powersupply has the appropriate PCIE power connectors and their hooked up, and second are you hooking a monitor up straight through a DVI cord or are you using an adaptor by any chance? I can think of 3 scenarios off hand, first off, if your using an adaptor, often times if you dont use the adaptor made for that specific card it won't translate the signal, second is not enough power, for example if you dont have all the PCIE connectors hooked up, which means the card will get partial power (they still get some power from the motherboard) enough to maybe run the fan but not enough for signal, and last but not least, and probably the most likely if its straight through a DVI cable to a DVI capable monitor and its all hooked up right-you got a lemon. RMA it. :D

Not sure why the links got killed, they should work now. I am hooking the new card up straight through DVI, same as my 8600gt that I am using right now, no adaptor. The 9800 gtx+ uses one 6 pin connections which seems to be hooked up fine, the fan is spinning on it. The PS has 2 available 6 pin connectors, tried both.

Hoping I dont have to RMA but if I have no progress by tommorow I will just return it for a different card altogether. This 9800 gtx+ is huggggge. Biggest card I have ever installed by far.

feasible it could be the 6 pin connectors on the PS as well. did the 8600 use a PCIE connector? To my knowledge they didnt.

The 8600gt was just a direct plug into the PCI-E, didnt need external power like this new card

Probably will not make a difference but did you go through the procedure of uninstalling the software\drivers for the 8600 prior to removing the card?

thankyou thunderZ I didnt think of that thats a good idea. Might not make a difference, but I have seen driver conflicts like that before.

I sure did, I was think maybe it had something to do with onboard video but that wouldnt make sense because the 8600gt should have the same problem if that was the case.

Well, for lack of a better idea, check the BIOS. Either disable the on board or point the display to the pci slot depending on the options available.

Even though this PS supplies 25amps on the 12v rail and the card requires 24amps I am getting some suggestions that the PS doesnt have enough juice. Newegg has quite a few reviews of users running their gtx+ with this PS though so that seems to be conflicting info. Either way this PS is extremely loud, I may just get one of a little better quality and definately one that is quieter and see if that helps out at all. Any suggestions?

A little higher wattage won`t hurt either.

Keep us posted what happens.
