Did you use a driver sweeper to rid your system of all traces of your Nvidia drivers? Also make sure you download the latest drivers from the ati website...

No mate i didnt use a driver sweeper
could this effect it
i did download the latest driver though

Can your PSU supply enough power to it? Seems like a heat problem, if you can quickly go into Catalyst Control Centre and check the temperature of your card or just put your hand close to it when its running normally.

I don't think not using driver sweeper would have resulted in white lines and artifacting tbh, overclocking or heat issue.

RMA it if your PSU is fine

its a tagan 480w
i thought that would be enough
ill put the card back in tommorrow and try it again

When you uninstalled the 8800 drivers some files will have been left behind. These may or may not cause problems when installing ati drivers onto your system which is why it is good to use a driver cleaner to remove the leftovers

What he's saying is happening, doesn't seem to be anything to do with the problems people experience when they have reminents of nvidia drivers left. It seems to be either a power supply issue or overheating.

I'm pretty sure artifacting isn't something people experience when its simply remaining bits of a Nvidia drivers left on the system. You can try doing what he suggests, its always a good idea but very unlikely to solve your problem.

480w seems fine for the 4850, but it may be the problem if its a few years old and you have more components than the average system (such as multiple hard drives, 4 sticks of RAM, lots of USB devices etc).

I'd still settle on the card overheating or simply faulty.

It draws similar power to the 8800gt so the PSU is fine.
2D clock artifacts = RMA time tbh (once your certain its not drivers)
