Aurora R6, flashing yellow power button, no solution
Hi,
I'm at my wits end. I know when the power flashes 4 times, it means bad memory. I've put brand new memory in and it still flashes 4 times.
Here are the steps I've done so far since the machine stopped turning on:
1: Disconnected all cables and ran the PSU diagnostic. All good
2: Connected each cable one at a time and ran the PSU diagnostic. All Good. Replaced PSU anyway. Still no power up
3. Replaced motherboard new. Also replaced the power button. Machine powers on now, but flashes 4 yellow (power button)
4. Replaced RAM new. Still flashes 4 yellow
5. Removed SSD and plugged in new SSD (for the heck of it). Still flashes 4 yellow
At this point I've replaced EVERYTHING NEW in the case with the exception of the video card and I still have 4 flashing yellow.
Any insight would be greatly appreciated.

Technicians test computer Power-Supplies with a "Digital PC Power Supply Tester".
If you replaced PS with other than Dell-OEM model, you must replace wiring harness also.
Yes, make it as plain and simple as possible. Only goal right now is POST and BIOS access.
No video-card is needed if you are using on-board video.

Sounds like a bad motherboard (or maybe one of it's components like RAM or CPU).
Be sure machine is un-plugged (and flea-power dissipated) before each hardware change. It's pretty easy to eventually blow something if not.
Not all used (or "working pulls") parts actually work 100% correctly. Some sold on eBay and similar are out-right broken/trash.
