I'm not sure what rtl70.bpl is, google says its related to some sort of image converter. I suppose you could uninstall & reinstall that program. Same goes for printer drivers, might want to see if your printer is in device manager as well. Make CERTAIN 'Plug and play' service is turned on & set to automatic from start - run - services.msc - enter
Definitely time to do a clean uninstall & reinstall of nvidia drivers. Use this link to show how to do a clean uninstall.
Then reinstall the drivers.
You can uncheck all nvidia startup items in start - run - msconfig - hit enter - nwiz, nvmctray, and NvCplDaemon. You can also go start - run -services.msc - enter and disalbe the nvidia service as its worthless.
