Dell Optiplex 9020 PSU Problem Part 2

Hello,

Sorry, I am re-posting because I have taken a video of the startup process. Thanks for the previous replies on
installing software to identify the problem, but at this point I can't even access the OS for long enough to make
any changes.

I have a refurbished Dell Optiplex 9020 that turns on and off randomly. I hope this thread can help anyone else
with similar problems, and again I really appreciate any advice and apologize for not replying to previous threads.

Here is a link to the video (an mp4 file hosted on Wetransfer):


Thanks in advance!

Thanks for asking! I can definitely provide any needed specs.


As far as posts by commentators on the original thread:

1)
If you bypass the power switch does it make a difference?

Could be the PSU.

I do think it is the PSU at this point. I can't even keep it on long enough to access the OS or enter through BIOS (it will power off before
I can make any changes).

2)
Could be a heat problem
Can you go here and download speed fan and install Click On Me .
Run speed fan then click on the Exotics tab > show the magic. post a screen capture. To do a screen capture in Windows 10 press the windows key and the print screen button together. It will put the image in Pictures>Screenshots

I can't install any software as the PSU problem is getting progessively worse. I was using the computer last summer in extreme heat
for many hours on end in a very hot room, so I wonder if there is hardware damage from that.

I am wondering if replacing the PSU is worth the cost. Any advice would be greatly appreciated.

Thanks very much for the assistance and consideration.

Best Regards,
J
