System shuts down in less than a 1 min on startups

I have a Sony Vaio laptop that shuts down on startup. Worked fine other than this. I’ve tried to get into BIOS and safe mode to search or repair, but it won’t stay on long enough to check. Thinking maybe the power supply, but the fact that it shuts down at the same time frame – consistently, wasn’t sure if it was software related.

Any suggestions would be greatly appreciated!

Thanks
