I searched the site before posting and can't find a post that has this issue resolved.
I have an Asrock X99 Extreme 4 that has been in service for over 9 months without an issue. It is paired with an Intel 5820K and Crucial Ballisitcx BLS2K8G4D240FSA (2x8 GB). Graphics is handled by EVGA GeForce GTX 960 SuperSC ACX 2.0+ . All of these are powered by a Seasonic SS 520GB PFC F3.
BIOS is v1.5
While I was watching a saved DVD video from my local hard disk, the system just powered off - no BSOD, no thermal warnings. It just died.
My subsequent attempts to power on the PC failed. Each time I pressed the power button, the fans would spin for a few seconds and then power down.
In the process of troubleshooting, I took everything apart. When I breadboard-ed the system (CPU+Cooler+Mobo), I got 3 long beeps, indicating missing RAM. When I added a single RAM in Slot A1, it then gave me 10 short beeps (this is before POST, and means missing/undetected VGA - pulled my hair our assuming that this was CMOS read/write error ). After adding the graphics card and hooking it up to a monitor, I was able to see the boot screen (I cleared the CMOS in between as well). I went into BIOS, browsed around for about 10 -15 minutes and boom.. it powered off again.
Everything was idle for about 2 hours while I cleaned the whole thing, so that idle period seems to have bought me about 15 minutes of power up time. I am at a loss to see what else would go wrong. I breadboarded on a non-conductive surface. The only component left to detach is the CPU & Cooler. Currently trying the CMOS battery reset method (power off, wait until residual charge goes off, switch reset jumper, pull out CMOS battery, wait 4 hrs)
Any suggestions / guidance you can give is much appreciated.
I bounced this off the Asrock forum and got a suggestion to try with another PSU. Definitely on my to-do list tomorrow.
Regards, J.
