I built and tested my new ASRock system on the Bench outside the case.

Configured and Tested, Worked fine, installed Windows 10.

 

Components:

MB =                ASRock X299 TAICHI XE

CPU =             I7-7820X

Drive =                         Samsung 960 EVO Series - 500GB

Memory =         G.SKILL TridentZ S 32GB (4 x 8GB) DDR4 3200 -   F4-3200C14Q-32GTZSW

Cooler =           Corsair - H100i v2

Power Supply = EVGA SuperNOVA G3 1000W

DVD/CD =        https://pcpartpicker.com/product/2v9KHx/asus-optical-drive-drw24b1stblkbas" rel="nofollow - Old AMD video card and 1080P monitor.

 

 Fractal Define R5 case came in and I moved internal components to Case.

Powered on and nothing just black screen..  No BIOS    Dr Debug = 00

Just MB LEDs & Fans running.

Checked and double  checked all cabling, CPU power etc..

 

DR Debug suggests checking CPU Install so I removed inspected CPU (looks good) and Re-Installed

 

Tried Clearing CMOS  using Button,  using  MB jumper and removing Battery.

Powered on and still nothing just black screen..  No BIOS  Dr Debug = 00

Just MB LEDs & Fans running.

If I let it set , It does cycle MB power , going dark  (LEDs  and Dr Debug off) every minute or so.  

 

Please help.  

Ideas for Tests  ?

Did the MB blow a fuse?

Did I lose 12V?

Did the CPU go bad?
