Will a computer not be able to recognize certain camera because of too many games downloaded on your computer?

I have an EMACHINES computer and I have never had any problems transferring my pictures from my HP Photosmart M525 digital camera using a USB cord until today. Someone told me my computer might not have enough rams because of too many computer games being downloaded. All it says is "Device Unknown" and I feel like I have tried everything to get it to work!Will a computer not be able to recognize certain camera because of too many games downloaded on your computer?

First re-install the driver and software for your digital camera, if this doesn't work then uninstall all the USB ports from Device Manager and reboot the computer. Windows will re-install new drivwers for the USB ports. This should fix the problem
