HP ProDesk 600 G3 Desktop Mini PC
Microsoft Windows 10 (64-bit)

Searched everywhere and cannot find an answer to this. I did find 1 or 2 other posts with a similar issue but they had no response so lets see if I can get something.

Just bought this ProDesk 600 G3. i5 6500T, 16gb ram, 256gb nvme. It's a certified refurbished by a Microsoft Authorized Refurbisher (researched the company, they are legit), I know, it was cheap and met the specs I needed. So, got it all set up, went through setting up Windows 10 Pro, was getting all my programs installed and the junk software removed. The computer is only going to run Spotify, a web browser, maybe do some light svg editing in inkscape, that's it. Was getting logged into everything, mapping folders from my server for access to my business files and out of nowhere it completely shut down.

Initially I thought it may have overheated, maybe the fan wasn't working or the heatsink wasn't tight, something like that. Let it sit for about 30 mins to cool down and tried to reboot it. Nothing. I could press the power button and it would light up white then immediately shut off. If I held the button, same thing. So, I unplugged the power and pressed the button to dissipate any power left in any capacitors. Let it sit for 2 mins then hooked everything back up.

Now when I plug in power I get a single white led flash from the power button about every second, the fan kicks on for a split second and then shuts off. It will continue to do this until I unplug the power. According to the manual a single white flash is not used as a diag code and neither is a continuous white flash. Any ideas?
