HELP! can't find my ATI Radeon HD 4550 graphics card

The driver for that 4550 will not work from anywhere but HP as they have modded and/or added bits to it so that it works with the integrated in the i3; that is why I said get them only from HP in my last post. Same applies to the driver for the integrated Intel; won't hurt and might help but I would download and install the latest one that HP has for it as well (and it has to be installed before the ATI driver).

Will i have to uninstall the driver i installed earlier today for the ATI? I don't know how to do that. I would usually do it through device manager but seeing as the ATI card isn't showing up in there i don't know where to go to uninstall it.

Programs and Features - ATI Catalyst Install Manager. Doubt that the driver even installed if the card isn't showing in Device Manager. At best you probably got the CIM and possible the CCC, but not the driver.
