New 9800GTX help!

did you uninstall the old drivers?

Yeah i've unistalled and reinstalled a few times but still the same result.

I have vista ultimate, 460w psu (not quite sure what make), 4gb of ram, core 2 duo 2.13 Ghz, asus p5w dh mother board

no i only have one, i thought that as there was only one of the 4pin to 6 pin adaptors supplied that only one was needed, i was quite puzzled about there being 2 slots though. also i didn't have any free 4 pin connectors to use. i fiddle around with what i've got in atm and free some up and try it out. but i've gtg out soon so won't have time to do it now. i'll post back later with my findings

mine only came with the one molex to 6pin adapter but luckily i had the one that came with my old card still. Rearranged things in my case and now the airflow is much better around the case and freed up some power leads for the card and now everything is perfect. cheers for all your help.

Thats right makotech22 2, i agree with you. To power up the 9800 GTX properly you really need a minimum 500W or more (my opinion), even in the brochure it said "Psu with minimum 450W". But, IF you believe what said in the brochure, well i assume you are one of the fraud victim

For example, you are have a C2D (stock clock i guess), 4 GB of Ram and ASUS P5WDH. Then how many HDD you've installed, how many Optica drive you've installed, how many fan you've installed? Every game, specially the next generation, it's really really power and resource eater. Even you read in the certain hardware official website, they're claiming that their product is energy saver or even whatsoever. But the fact is the more complex of a process, the more power and resource use and the more heat generated. So if you still using your old psu i don't mind, its you system, but what im concerning for you is your system lifespan won't last long enough to use. Think guy's, computer that used for game is use a lot of power and generate a lot of heat. Even you buy a case for what... say a $1000, for example (but maybe there is no case that price that high. Who's gona buy it? or even maybe there is?) that wont work for a psu with 450W. So add power to your system, since 9800GTX is a BIIIG card (for wallet and for case), if you wanna longer the lifespan of your hardware.

Man, even more reason for me to skip this stupid 9 series. The 9800GTX and the G92 8800GTS are the same thing, yet the 9800 requires 2 power connectors!!The F~ck is that?!?!?
