Hi all, I am checking to see more definitely if this sounds like a dead mobo. New build/ everything's new. This is my first new build in over 7 years, so I just wanted to see what you thought.

The issue is: **CPU led/Memory OK! stays on and red. No beep. Nothing on the monitor. Case lights, fans, GFX card fan all on.

Specs:
MOBO:
ASUS M5A99FX PRO
CPU/Cooler:
AMD FX-6350 AM3+
COOLER MASTER Hyper 212 EVO
GFX:
XFX Radeon HD 7850
MEMORY:
CORSAIR Vengeance
PSU
SeaSonic X650 Gold
1 TB HD, DVD ROM, sd card reader

1. Powered up with everything in and:
**CPU led/Memory OK! stays on and red. No beep. Nothing on the monitor. Lights, fans, GFX card fan all on.
2. Re-seated everything in same slots, including CPU w/ new thermal paste, secured cooler snug not over-tight, verified speaker was plugged in.
**same result as in 1.
3. reset cmos.
**same result as in 1.
4. took battery fully out, reset cmos.
**same result as in 1.
5. Cycled mem one stick at a time. Tried each in both A2 and B2 slots.
**same result as in 1.
6. Left one stick of mem in for the rest of testing. Unhooked everything from PSU/MOBO except GFX card, CPU, mem. reset cmos.
**same result as in 1.
7. Swapped GFX card.
**same result as in 1.
8. Unhooked GFX card. Booted w only cpu, mem.
**same result as in 1.
9. Shut it all down. Got angry enough to kick a puppy (but didn't). Cried a little. Sad Face. Then came here.

Thoughts? I am pretty sure it's not the PSU, but honestly I didn't try another. I am figuring new out of box failures lean mobo.

Thanks in advance,
-Sparky

Thank you for the reply @Tradesman1. I appreciate it. Replacing everything down to the PSU should always be done.

<feels like a dum dum>In getting ready to bench it, I grabbed a new PSU. In the process I realize the 8pin wasn't fully seated. I checked and rechecked the 24 so many times, but never the 8. I had hidden the cable so well, I totally looked past it every time. </feels like a dum dum>

So, lessons learned; 1. maybe bench test everything before assembly, 2. if there's an issue troubleshoot everything if you can (even a new PSU). You might just be punch drunk from staring at it and thinking, "Everything's new, WTH?!"


BIOS came right up. Win is installing <knocks on wood> ...

Thanks again!!!

No problem, and your right, always a good idea on a new build to do so on abench, that way you know if it works, then when in case if a problem, probably missed a standoff, have something touching where it shouldn't....easier to track the problem , rather than digging through everything in the case..............and congrats, great cable management if you kept it hiddent than well, sounds like a clean looking rig inside, I like that ;)
