Runescape Error Problem

[DPS]

Ok so ever since i installed world of warcraft around 3 years ago RS has never worked. I've system restored to try and change settings back to what they was, but still have the same problem. I've looked for hours and hours on end on google trying to find a way to think this problem but to my luck nothing. can you help?

Have you tried removing and reinstalling atikmdag.sys?

Update your drivers and install the newest windows service pack.
