|Your CyberPower link is to a configurator, I have no idea which hardware you chose. If your C: drive is a 40GB SSD, the only things that should be installed on it are Windows, the hardware drivers, Windows Updates & your security software. Everything else should go on the D: drive. When installing to D, things may be a little tricky, but as long as you pay attention to what's going on & don't just keep clicking "next" without verifying where the files are being installed, everything should be fine.|
It sounds to me like you need to uninstall everything that you put on the C: drive (except what I mentioned above) & start over.
