I decided to reinstall Rasbian onto my Raspberry Pi, via NOOBS. I'm using all default settings except I have the thing overclocked at 800mHz. I type things into the CLI but my inputs seem to be not registering consistantly. When i finally log in I type startx to get to the GUI. I experience the same issuses with the LXTerminal. Sometimes the mouse freezes, and I can't move it, and I have to reboot the system. I decide after 5 times of experienceing these issues, and rebooting, to reformat the SD card and reinstall Rasbian, via NOOBS, ALL defaults and I experience the same issues. I know it is not my keyboard and mouse becuae I tested those on my normal computer and they worked fine. Its not my USB ports because I have a usb fan and it worked on both of my USB ports.
