I first thought it was my power supply so I got a new one, it has 850 watts, I scanned my computer for viruses and it still shuts off. I have a I6 proccesor, a gtx 1050 and a cyber power PC, I tried to get speed fan and it says my fans are over 90℃ but I know that isn't true. Whenever I open task manager at startup it says 100% disc is being used. But later it goes down to about 8%. Also my windows says it isn't updating properly and it says to click this message to fix it, but my PC shuts off when the download can only get to about 30%. Help.
