I recently got myself a Sapphire HD 4870 Radeon Graphics Card ATI 512mb and it is causing me headaches!

First the gaming would crash every 30 mins or so, was a common problem and i flashed the bios it and that got solved. But now i have the problem below every morning for some reason

The only way i can fix this is by fluke, uninstalling the drivers, sometimes it works, sometimes it doesn't.

Any fixes please?

I think it's caused by your VRAM, uninstall your drivers, and the registry use "DriverSweeper" do a clean install of the latest drivers and check again. If that doesn't fix anything its clearly your VRAM. You could also try to underclock your memory with a overclocking utility like atitool or rivatuner

Do you have Nvidia drivers hanging around by chance as well? If going through the control panel and unistalling that way doesn't work then I would do the suggestion above by using driver sweeper but make sure there are NO video drivers left.

What driver version are you using for your card?

i had the same problem with my 4850 when i updated to 10.6 drivers, but i found my old 10.4 installation in my hard drive and uninstalled the 10.6 drivers and installed the 10.4 drivers, and its fine now, try downloading the 10.4 driver, should work for you aswell

i've used driver sweeper and uninstalled the drivers plenty of times..

I'l try out the older 10.4, currently using the latest 10.6

And my psu is arctic power 550 watts..

Had the same problem again this morning lol.. fixed it by removing the graphics card and plugging it back in.

your psu is more than enough, but there's a lot of ppl having trouble with the new driver, so if going back to an older functional driver doesn't work, then i don't know what does
