Well ive had this problem with my 9800gtx+ for awhile, it seems to have to go in a certain way and i have to force it to go i nthat way most of the time, if its not in exactly that way it doesnt work. The green leds are on meaning both power connectors ar ein and working and the fan spins up but it just doesnt spin down. Ive tried a few times now and cant get it to boot up again with my new mobo and ram (it was working fine from the first boot). Everythng else works because i can hear the hdd starting to boot up and everything and my g11 and g9 light up. Any ideas on what to do?
