I have a E1-531 and the error code 0xc000021a came up and then my laptop switched off by itself.

I do not get the blue screen.  I have tried to turn it on but it will only turn on for 3 seconds and then the Acer logo appears and then it turns off by itself and then it turns on, Acer logo appears then it turns off, same loop....  What could be the cause of this and can I fix this myself??

    Hi JackE, it is still on 8 as I didn't want to update to 10

    OK. Completely shut down the power to the machine by pressing and holding the power button for 5secs or more. Then turn the power back on and ***immediately*** start tapping the F2 key to enter the BIOS menu. Does the BIOS INFORMATION tab detect a hard disk drive with its serial number etc? Jack E/NJ
