Problem with Radeon 6770 upgrade

[PaulMTC]

Hi,

I have bought an XTX Radeon 6770 as an upgrade for my current pc.

I installed it but there is no signal going to the monitor.

When i put my old card back in (radeon 4670) everything works fine.

Has anyone got any ideas of what could be wrong?

i have plugged in the 6 pin power connector also so it's not that.

My spec is:

• 
  motherboard: MSI P31 Neo2-FR Intel P31 (Socket 775) PCI-Express DDR2 (MB-095-MS) ..... [ms-7392]

• 
  processor: Intel Pentium Dual Core E2200 Socket 775 2.2GHz 800FSB

• 
  psu: ocz 500w

Thanks.

Paul.

Tried a different mintor cable? Tried the other display outputs on the card?

Try the other outputs, then try it on another PC if you can and if you have no luck send it back for a replacement.

Shame a 6770 would have a great upgrade for that PC. I have a 5770 which is the same card and I can still play lots of games at 1920x1200 at decent settings (Empire Total War, Dirt 3, GTA IV, Fallout 3, Mass Effect 2, Crysis).

Yep I was looking forward to the upgrade as it should make a big improvement.

I tried the other display output on the card and a 4 colour "self check" thing comes up and moves about the screen.

I'll be annoyed if its the card as its ready a replacement one for a previous faulty one I got from ********!

It's actually a 500w psu not a 550w - should that make a difference?

Cheers,

Paul.

did u fully uninstall the ati drivers first? then plug your 6770 in? re install ati drivers?

It should still display at boot regardless of drivers.

true,cant think what else you could try? if you have another pci-e slot try it in that or test the graphic card in another pc if you can to confirm its working

not too keen on xfx either,i only buy sapphire cards but thats just my opinion

The card might be too new for that board. 5xxx series cards dont post on my asus a8r-mvp either (s939) Might be worth checking if a bios update is available for your board if you get to know the card it self is ok.

That's a great idea - i will check for bios update.

I have a modular psu (ax750), and by mistake plugged in a 6pin power lead to my 6970 that didn't have pci-e stamped on one side of it. My card wouldn't work until I swapped it for the one marked pci-e.

Can you try the card in a friends computer to see if it works in their machine?

EDIT

Just checked on AMD website, does your psu meet this requirement.....

450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended

the psu meets this requirement - its a ocz 500w with a 6-pin pci-e connector.

also - i checked the bios and it's up to date. the "intel inf" driver for the motherboard was not up to date however - should that make a difference?

i'll try the card in another newer model computer. if it works - does that point to my motherboard not supporting it?

cheers,

paul.
