I didn't have this problem up until 2 days ago now when the battery is at 100% the computer shuts off when unplugged, but if it's at 99% or below this doesn't happen. I have no idea what is causing the problem.
I recently updated my Nvidia graphics driver, installed EVGA precision (seems to be working fine), and tried to use Riva-Tuner but when opened it shows this error:
[Cannot load Rivatuner64.sys driver. please ensure this file exists in RiveTuner's folder and your account has admin privileges]
I did not check to see if the file was there, and then after pressing OK another message appears:
[Driver signing enforcement must be disabled in order to start under Vista x64. Do you want to disable driver signing enforcement right now and reboot the system to apply the changes?]
and I said yes. I know that was was stupid but I believe this is the cause of the problem and would troubleshoot it myself but am afraid I might screw it up, so some advice from someone who knows what they're doing would be very much appreciated.
