I recently bought 2x1Gig PC3200 ddr400 ram on ebay for my ga-k8ns ultra-939 motherboard and cannot get my computer to boot with it i have tried each stick individually in slot 1, both side by side in slot 1 and 2 and also slot 1 and 3 and when i turn on my computer i can hear the drives initializing and my hard drive spining my fans all operate even on my video card but it sends nothing to the screen when i put the old ram back in (2x256 ddr333 origanally in slot 1and 3) it boots as normal. also if i use just one of the old in slot 1 it will boot. if i mix old with new in different combinations of slots i still get no video.

Do i have incompatible ram or what could be my problem?

put your old ram in and go to this link to see what memory your motherboard supports...you probably bought the wrong ram for your system...

you need to get ...
unbuffered...non ECC...PC3200...ALSO CALLED DDR 400...or PC 4000...
stay with the major brands....crucial...corsair (my favorite)... Kingston...OCZ...PQI...

you can SOMETIMES mix brands...but to avoid any potential problems...get all your memory the same speed ...in your case PC 3200..and from the same manufacture...
