Hello! I don't post here often as I'm usually very stubborn and think I can always solve my PC problems myself, but after days of troubleshooting my main PC, I've nearly given up. I recently bought a CoolerMaster MasterLiquid ML240L V2 RGB to replace my old Hyper 212 EVO as I wanted to experiment with more serious overclocking. The installation had went fine for the most part until I went to boot up the PC. My motherboard wouldn't even post. I began troubleshooting and found out that the PC boots just fine if there is ONLY one RAM stick installed, but if theres more than one stick installed in ANY configuration, the PC does not post. The motherboard status LEDs cycle between a red LED (CPU) and an orange LED (RAM) after eventually stopping with the power LED on the motherboard turning orange and staying there. The only new part I installed was the CPU cooler. In my process of troubleshooting, I uninstalled the AIO cooler and reverted to the 212 EVO (exactly how my setup was before) and the PC still wouldn't load with more than one RAM stick. I've also tried resetting the BOIS multiple times, by taking out the CMOS battery and power cycling the PC with no luck. The only cause of the issue I can imagine was that during the installation of the new cooler, I had taken the CPU out of its socket to clean it, and had accidentally ignored the arrows on the CPU and motherboard on how to place the CPU (I was making the installation at 3AM) and might have damaged a pin in the socket, although I couldn't see any damage visually. Absolutely any advice/help is appreciated. PC specs are below.
