Dell XPS 8940 - (2 Amber, 1 White) after trying to upgrade ram | DELL Technologies
June 27, 2021 - I was trying to upgrade my desktop with this CORSAIR - VENGEANCE LPX 32GB and tried to add it with my 8gb HMAA1GU6CJR6N-XN. Yes, I set it properly, but when I turned it on, it won't boot (blank screen and it shuts itself off after about 20 seconds). I tried to remove the CORSAIR - VENGEANCE ram and put the 8GB HMAA1GU6CJR6N-XN back the way it was however it still won't boot. Then I found out that I am actually getting the 2 amber 1 white blinks (which is the case of CPU failure).

@yarrumbak S5 VID 3, 2 3 blinks followed by a short pause, 2 blinks, long pause, then repeats Video subsystem configuration activity in progress or video subsystem failure. Troubleshoot, narrow down the issue by removing cards one by one to determine which card failed.

It indicates PCI of Video card/chip failure Since it's 5 months old, warranty would cover it, you can try Removing power cable from Tower and holding the power button down for 30 seconds to release static charge and than powering it on again If no go please remove the monitor from graphic card and plug it to the Motherboard, do not play with any internal components and call Dell warranty for Motherboard replacement.

July 5, 2021 - However when I connect the monitor to the onboard DP or HDMI the machine boots fine. I have checked the 8940 Service manual and the 3,2 blink seems to indicate a "PCI of Video card/chip failure".

From the link you posted above, 3 Amber, 1 White is CMOS Battery Failure.. Since you left it unused for so long, the battery lost power and is LOW.... replace it. Not too sure what you mean by 'I found what I believe is in SSD power that is not plugged in. (5 black wires together) For the life of me though, I cannot locate where it is supposed to plug in to.' Which drive power line or where to connect it to the motherboard? However, all the board connections are detailed here, https://www.dell.com/support/manuals/en-us/xps-8940-desktop/xps-8940-service-manual/installing-the-system-board?guid=guid-25d14fe1-5fc7-4b24-939b-56aa714aa638 and not sure if you mean #10-12, or even #15 or #18?

From the link to service manual, it seems that the error indicates something wrong with memory. You may try to reseat all memory modules and test again before contacting seller for a return.
