My PC keeps on crashing

if your PC keep on crashing, to my idea first check your hard disk. if you have enough storage is ok, 2 check if your don't have any virus on the machine, if not then what i suggest for you is do a troubleshooting by hard reset. if you are using laptop remove the battery for some minute then put back and on it again , if this doesn't work use air dryer to clean the board mayebe there is dust around the cpu. 3) you can also do window reset troubleshooting
