I recently bought a radeon 5870 for my gaming rig. Problem is: when my computer starts, only a cental square part of my desktop is shown, the rest is all black..I launch CCC, go to displays page and rotate the display, then canel that, the whole desktop is shown..After that if I launch any game the card will not go to 3D mode, but it'll remain in idle colcks...To resolve this I restart the PC, and if the whole desktop is shown, then I know everything is going to be OK.. This problem appears to happen randomly at startup. Everything was perfectly fine with my previous 8800 GT.
N.B I formatted and installed a fresh copy of windows and I installed a new 800w PSU prior to installing the new GFX card.

I would check in your add and remove programs and make sure all Nvidia drivers and software are uninstalled. I know sometimes strange thinks happen when the old drivers and software are still lingering around.

Does the whole desktop appear or just a part?

If it is the whole, it sounds like a problem loading the correct resolution and it is set as 1:1 pixel mapping in either the monitor or CCC scaling options.

As you have reformatted, it will not be old drivers but I would try out older cat's as that is an odd problem.

Thanks both 4 the reply.
@ jay2tall: I reformatted
@strangestranger: Only part of the desktop appears, and strangely it isn't exactly the central part, but rather displaced alittle towards the left lower corner!

Anybody else got any other idea..The problem still persists with Catalyst 10.4. It is even worse now, it happens after every restart. And I was wrong about which part of the screen is displayed in the central area, actually it's the upper left part, if that makes a difference.

It is still under warranty, yes..But people here are stupid when it comes to high end H/W, if I can't fix it, I don't believe they can! And I believe it's a software issue, but I'm not sure.

Try Re-installing OS and All drivers, and if that doesn't fix it, take it to them and say exactly this "Its not working".
