Hey, gang. I have an issue with a new build that really has me stumped. At startup, it powers on for about three seconds, powers off for about 15 seconds, powers on for 3, and so on ad infinitum. Before you jump up and say it's the PSU or RAM, please read all the things I've already done to address it because I've ransacked the web looking for ideas. NONE of them have had any impact: it continues to do the same thing. Intel blames the motherboard. MSI blames the CPU. Sigh.
First, the Specs:
MSI Z390-A Pro Motherboard
i9-9900k w Cooler Master
2x32GB DDR 4 4GB RAM 2666
Zotac 1050 Ti GPU
2 x HDD, 1 x CD/DVD
Actions Taken:
Tested and tried 1 900w PSU and 1 650w PSU (both high quality). Both passed tests at perfect specs.
Also tested both with different cables.
Removed RAM and rotated 1 and 2 sticks between different slots and combinations.
Reseated and cleaned ALL cable connections and hardware.
Removed all unnecessary hardware items 1 at a time.
Replaced motherboard with same as spec.
Replaced CPU with same as spec.
Cleared CMOS both with the jumper and by removing battery for up to 1 hour.
Removed motherboard from case and ran all combinations of above.
I'm not a rookie: it's not ESD.
I can't find any other ideas to even try at this point. It doesn't appear to run POST or, if it does, it powers off before completing. The only "error" code I get is "00". This is just a lower end setup for a friend but I'm already almost $1,000 into EXCESS costs not to mention 10 hours more work than expected. I am absolutely stumped!
Has anyone ever encountered this before? Any fresh ideas? Any help GREATLY appreciated.
