This computer has been used extensively for the past few weeks for stay at home work. Today, it was shut off as normal. Deciding to get back to some work, we turned it on and what it does is:
Turn on - the speakers turn on, and the fan in the back starts spinning
Turn off - In one literal second the PC shuts off completely.
Loop - it continues to do the loop mentioned. I unplugged the power cord as I was worried of any damage to the components. About 5 minutes later I plugged it back in and attempted to turn it on, to no avail.
I have no idea as to why this might happen, because again, it has been running the same few programs for the past few weeks. The PC had been dormant for a while but was recently brought up to date (Windows 10 updates that needed installing) due to the need to work from home.
Any tips would be greatly appreciated. Nothing even comes on screen as it barely boots up, so I can't access any software tools at all.
