HD 5770 Issues - BSOD

I just got one of the new Sapphire 5770's from OC on Tuesday thinking I would upgrade from my old 8800 GT and give this box another year.

However, the thing is giving me no end of gyp :( It locks up the machine whenever I turn AA on and fire up a game. Pushing textures up to a high setting also seems to cause lock ups after a while (or using Trilinear/Anisotropic filtering). I saw a post somewhere stating that there is a known issue with drivers and AA but have seen other people post they have these running with AA.

I have been trying to play Age of Conan and Dragon Age : Origins. Any help would be appreciated.

Running latest 9.11 beta drivers.

GPU-Z

Comp specs are

Intel E8500
ASUS P5K Pro (1303 BIOS Revision)
4 Gig of RAM
Windows 7

Everything is running at stock. Power supply is a pretty meaty 650W job as I recall.
 
Cack .. quick Google says the ASUS P5K Pro doesn't support PCIE 2.0. So basically this mobo is incompatible with this vid card ? ie I need a new mobo as well ?
 
Welp, reset the BIOS and tweaked the settings so that CPU-Z shows x16 on PCI-E. Uninstalled drivers and went back to the official 9.10's.

Still BSOD's if I turn AA on :(

PS. To answer the question above, yep MOBO drivers are up to date.
 
Still happening but I have an idea and need some input.

Now how this happens is a game can run for a while (say 30 mins with AA etc on) then the system locks up. At first I thought it was heat but I have ruled that out with some use of Speedfan.

Now, the PSU I have is a Seasonic S12 600w which only has 18amps on the 12v rail. I am seeing posts that say a HD 5770 will need up to 30amps on the rail. Is this the case and if so do I need a new PSU ? :)
 
Excuse me if I am being thick Raven but there are two power leads coming out of the PSU (one for each rail) and only one of them is plugged into the HD 5770.

I am assuming then that the max amperage the PSU can supply the card is 18amps (max per rail according to the PSU manual).

For example the equivalent Corsair PSU has 40amp on the 12v rail.
 
Right, so new Windows install as suggested.

9.10 drivers. Same problem.
9.11 beta drivers. Same problem.

New symptom though. When it locks up or the system asks for a reboot (say when installing or uninstalling drivers) the display is right off the right hand edge of the screen and the monitor h + v controls are locked. I physically have to power the box off and on again to get it to re-center. This is feeling more and more like a duff card to me.
