Hey everyone. I've been making some upgrades to my PC and have run into some issues. Here is my current part list . (I'm using the wraith prism cooler, which I couldn't add, as well as 4 case fans) Here is a brief summary of my upgrades leading up to the problem: Dec: new CPU R7 2700X -> R7 5800X End of May: new GPU RTX 2070 -> RTX 3080 Ti FE June: new Ram G.Skill Trident Z 3200 16GB -> Kingston Fury 3600 C16 32GB (yesterday) Note: after initially installing new RAM, boot was fine, then after launching Warzone 2, I got a BSOD with error: system service exception. After restarting, everything seemed to be fine until this morning when I found that I couldn't boot the PC anymore. The Problem, along with some troubleshooting steps: PC won’t post. Holding the power button does nothing. Nothing displays on the connected monitor. Plugged in keyboard does not light up. However, RAM and LED lighting on the CPU cooler (wraith stealth prism) are lit up, so they are getting power. LED on the side of the GPU does not light up. (Although I think this typically lights up at a later stage of the boot process.) Problem continues after plugging monitor into MoBo and removing GPU. (HDMI and Display port cables were checked independently and tried.) After swapping RAM back to previous. PC still won’t post. BUT now the power button works as expected again. (Holding for >4s forces power off). Keyboard lights up as expected again. Additionally, the motherboard backlight turned on AND it stays on after I hold the power button to shut down the PC. Typically, I’ve had this off at all times but when I did have it enabled it would never stay lit after turning off the PC. I'm not sure entirely why this happened. I know my PSU may be a bit weak after the GPU upgrade but I used the PC part picker calculator and figured it should be sufficient. I also used my PC without issues after the upgrade for 2 weeks so I think it must be related to the RAM. Alternatively, the new RAM pushed my power draw too far and fried some of the components. From what I've read, the problem is likely due to my RAM, MoBo, or CPU being dead. Fortunately, I'm in a position where I have my old RAM and old CPU. I've already plugged in the old RAM as mentioned above. It seems to have helped somewhat but I'm having trouble understanding what exactly is broken. I would like to avoid breaking more components if possible. Should it be okay to also swap the old CPU back or could I just be breaking more and more components? Any help is much appreciated!

Did you turn off XMP prior to installing the new memory? I recommend resetting everything to its previous working condition and removing the CMOS. If this resolves the issue, ensure XMP is disabled (it should already be off after clearing the CMOS) and attempt the upgrade once more. After that, reapply XMP for the updated RAM. If your power supply is near its maximum capacity, this might cause various problems and be difficult to troubleshoot without another PSU available.
