hi, we'll just bought new card and cannot get it to work.
coming from ati 5770 im upgrading to 480 with new power pack, i've unistalled ati drivers then swept with driver sweeper.
on installing 480 i get long beep then 2/3 beeps and no screen (black)
i can install 5770 and it work's again but trying the 480 nothing,ive just dug out old 8800 and it booted first time no problem.
what have i done ? if you need me too look into something please tell
any help greatly appreciated

ah sorry aint updated that ,new 1 is xfx black edition 850w
when 480 is in "ao" is on the onboard display but cant see that code in motherboard manual ?

 

[mel d]

other thing with old power supply it had a 4 pin supply to motherboard but new powersupply has 1; 8pin and 1; 4*4 pin supply ,i have 1 of the 4 pins installed like old 1 should i try the 8 pin?
will the motherboard need more power ?
why does it have a 8 pin connector on motherboard if 4 pin supply has been enough ?
cheers for any help

so computer works with 8800gs in but still black screen when 480 installed.
wont need to reinstall op system as nvidia 88 is working , so no ati/nvidia conflict ? i dont know would reinstall work ?

 

[mel d]

xfx 850w black edition have 1 6+2 in the 8 pin and 1 6+2 without 2 in the 6 pin.
stumped. could it be broke ? all the fans work when its on but gives black screen.

 

[mel d]

would there be any way to test , anything i have'nt already done ?
i havent got other computer to try it in but if ati 5770 and nvidia 8800 work with new power supply looks like faulty card ?

ok so when card is in top pci slot i get long beep and 2 or 3 beeps and no screen.
in 2nd pci slot i get display and"A single graphics card is detected in slot PCI-Ex16_2 or PCI-Ex16_3
Please move the graphics card to PCI-Ex16_1 slot for non SLI operation" so i can see something
3rd long beep and 2/3 beeps and no screen
the 2 digit code is a0 but cant see anything in mboard manual other than oa which is:
mouse init :initialized the mouse.
is there any way to move the primary pci lane to lane 2 ? (middle slot) as seems to work in that slot
thanks for input

 

[mel d]

[mel d]

[mel d]

double post sorry

 

[mel d]

[mel d]

post said delete before,but yeh all seem to have a half pin on either side.
card does click in and there isnt much space to tighten down at monitor cable end but i will try again later.
cheers for input

 

[mel d]

ah noprob gonna try once more then leave it for tonight.
step away from it cheers again

 

[mel d]

have done mate solid 8 pin installed on mboard,dont need to change anything in bios ?.
cards either broke or i cant see forest for tree's
if im running a nvidia card now i should be able to just plug new 1 in and away.

8800 in 1st slot and 480 in 2nd and it boots,plus there are green lights on back of 480(first time) but keyboard and mouse dont work."card in wrong place for sli"get screen output but no boot..
8800 1st slot and 480 in 3rd slot and long beep with 2/3 short beeps.no screen
so card broke or my pci slot not able to take /use this card ?
to much power for motherboard ?
cant think of much else other than stripping pc.
ati haven't left a code on my system lol will try again later on today.
cheers y'all

 

[mel d]

card broke ?
motherboard broke?
i haven't updated motherboard since i got it 2/3 years ago,but to me looks like pci slot isn't up to it.cant think of anything else.

 

[mel d]

hi, so after sending card back seems it works so must be motherboard and seeing as other cards work in it ,all i can think of is motherboard update .
any one got any other idea?
cheers
