The old adage is to restart your PC after serious problems such as the dreaded blue screen. Sometime you may need to restart a few times to knock out any bugs or data corruption that has occurred. Of course, if you are having problems, it is highly recommended to try and back up any important data before restarting or shutting down an unstable machine.
Occasionally you need to shutdown the machine completely and remove the power from ram memory by unplugging the PC from its' power source. This resets everything completely, whereas a restart simply reloads the data. If you RAM or other hardware is having a corruption problem - a shutdown will usually reset it to a proper functioning state. Good luck - but remember... backup important data frequently.
