5870 no display!!! help!!

so from what i can see and from what ive analysed i think it maybe my psu thats the problem. I really should try the card on another machine though but i dont have access to a larger psu.
 
i've set all my bios settings back to stock and tried to run the card again but it just runs the fan at full speed without any signal on my monitor. My computer posts and boots up windows normally though cos i can hear the windows log in sound.

I did a little research and found loads of people with the same problem but no fix. Some have changed psu's and mobos to get it to work.

Someone mentioned about letting it post and run for 5-10 mins then hittin the reset button and magically it worked? Going to try that now and see what happens.

I don't have a HDMI cable so thats a no go, i tried using the DVI converter that came with the card but still no luck.

i bought a 5870 back when they were first released and had exactly the same problem as you, weird thing is that wehen it was tested by ocuk they said it worked fine

i tried updating my bios and reseating the card multiple times but it still wouldnt work

i noticed that you have the exact same psu that i had back then so maybe that is the problem?

It might just be, did you ever fix it or did you just RMA it and got a refund/replacement?

I updated my bios last nite and still no luck, fan just spins up to max and no display or post now.
 
Don't suppose anyone knows a good way of testing for PSU stability and whether it is the problem? I have a Cheap chinese 750W psu here that i could use... I was thinking of using the psu tester technique with the paperclip on the 24pin and then just pluggin then 2 x 6 pins into the 5870 and have my corsair psu run my rig.

So basically corsair runs my rig and the cheapo psu runs my card?

What do you think? Worth a shot?

Btw do i need to update my chipset drivers when updating bios or will that not cause my graphics card to not be picked up? I didn't update my vga drivers either.
 
Sooo im finally home now.

Took the card back to OCUK headquarters today but couldn't get a refund because:

a) the product has been used and is opened.
b) occording to them the card is not faulty and posted on their systems.
c) Even if the product is not faulty i still cannot get a refund because the distance selling regulation (2000) doesn't apply to me because i bought the card from the shop over the counter therefore not long distance.

I'm pretty screwed tbh! I asked my local IT guy on the way back to do a check on the gfx card to see if it works on his rigs just to be sure. Will take my whole rig in tomorrow for him to look at to see what the problem is.

I suspect it maybe psu or motherboard but im hoping its the psu more than anything...

Or even better its just driver issues...

Either way i feel pretty crappy after spending £300's on a card that doesn't work and with pretty much no where to turn to so this is kind of a last resort.


If there is any other help or advice anyone can give me i would greatly appreciate it.

Thank you
Jay
 
This sucks, its like my word for their word right now.

If the other guy at the other shop tests it and finds its not posting aswel then what the hell do i do? Do i try and get a written consent from him stating it is not posting and push for a refund? I am not having this, i will not be conned out on £300 of my hard earned cash if indeed the card is at fault here. Should find out tomorrow whether it is or not.
 
I can't test it out because i dont have the card with me right now. It's been tested at my friends shop.

I'll try it tomorrow when i get it back.
 
I don't live close to them, it would have to be a few weeks time now before i make another drive. It's about 71 miles there and 71 miles back.

I will try the Clearing CMOS solution and loading up optimized default settings tomorrow and go from there. If not i'll just drop my whole rig at my mates place and let him play about with it.

This is dependant of course whether the card is indeed "fine".
 
ACTION PLAN:

Heres whats left to do after about 3 hours of reading solid from other peoples past experiences etc here is what i think would be the best thing to do...

As OLDPHART said, i will clear CMOS using the jumper but firstly:

1) i'll uninstall all graphics drivers using the programs manager and device manager
2) shut down computer, uninstall 5670 graphics card.
3) turn on computer in safe mode and run driver sweeper clearing the rest of the graphics drivers.
4) switch off computer and clear CMOS
5) Load optimal settings
6) turn on computer and disable onboard graphics
7) turn off again and install 5870

...8) cross fingers and hope it works?


ALSO

I loaded up driver sweeper and found i have nvidia drivers installed on my computer yet i have had no nvidia cards ever installed on my rig? PhysX possibly?

Thats fine and all but drivers dont matter on boot up.

So what would you suggest? Because like i said, when i first boot up i get no post whatsoever as if the card isn't even recognised. Sometimes i get boot up as i can see HDD activity and i can hear the windows log in sound but no display.
 
you mean changing it from x16 to a lower speed bus? Hmm not sure if i can do this but occording to cpu-z its always on x16
 
I got my card back today and they said its fine aswel so thats 2 companies saying its fine. Only thing left to do now is reset CMOS and disable onboard vga via bios and then what rolypolyman said, to take out 2 gigs of ram.!

Wish me luck!
 
I only have 1 but it doesn't matter, read the new thread and you'll see how i've got on with this problem.
