I have a HP laptop that is giving me some problems. It runs very very slow and often crashes when trying to run an application. It seems to be running at 100% CPU usage. The problem seems to have started when I installed a HP Photosmart program onto the machine. I have tried un-installing this program and I'm still having issues. I went to device manager and it said that "this device is either not connected or the drivers are not installed - mrtRate device." I do not know what to do. The only option I can see is to boot the recovery disk that came with the laptop, but I am affraid to lose my files. Any ideas? If anyone needs more information, as you probably will, I can get into the laptop to check whatever is needed.
