My computer keeps turning off ,and then rebooting,I can,t get it to stay on for more tan a minute.idid update a couple of things yesterday,and it has been like this since then, can anyone help please

last time i had this issue, it was on my Desktop PC and my Processor had an intermittant failure. however, there are plenty of other causes for this. i would start with a simple repair function, if repairing doesnt work, then run a factory reset on the device to wipe all data. if not, then start looking into hardware issues. (Processor, Mobo, Thermal sensors, PSupply, etc)
