1. Do you have .NET installed? If not you need to do that because CCC needs it.
2. Since you are getting the message to install new Intel display drivers, you MAY NOT have it disabled in the BIOS. Look for a section that says ONBOARD DEVICES, or something similar to that, and make sure the onboard video is disabled there as well. Some boards will automatically disable onboard vid and sound if they sense an addon, but maybe yours isn't doing that.
3. If you removed EVERYTHING that said ATI with the cleaner, you probably need to re-install your mainboard drivers, as one of those ATI entries is (or at least was, since it's been a long time since I've used DC) a mainboard driver.
3. Did you follow the DC instructions to the LETTER. A lot of folks don't, and it is important to do that with DC, of you WILL get into trouble.
4. Paragraphs are your friends...especially if you want someone to easily read what your problems are all about
