How do I fix a crashed PC?World

Indeed, sir. A crashed PC can be quite the nuisance, but with a few simple steps, you may soon have it back to its former glory. Firstly, try restarting the machine, often this is all that is needed to revive a reluctant computer. If that fails, consider booting into safe mode; this allows you to troubleshoot and potentially remove any problematic software or updates. Should all else fail, a system restore may be your best bet, returning your PC to a previous state when it was functioning correctly. If I may venture an observation, having a regular backup routine is always a wise precaution, one never knows when the next crash may come.
