About a month ago, I upgraded several parts of my PC, including the motherboard, CPU, RAM, and GPU. Everything was working great until yesterday when my PC suddenly shut down while I was watching YouTube. There wasn't a power outage, as my other electronics stayed on. Now, when I try to turn it back on, it gets stuck during the POST process, and I'm not getting any output on my monitors. The CPU and DRAM POST Status Checker LEDs are lit, which suggests there could be an issue with my RAM or CPU.
Here's what I've tried so far: disconnecting all cables except the power, monitor, and keyboard, shorting the CMOS jumper (since I don't have a jumper cap), removing the GPU to connect the monitor directly to the motherboard's HDMI port, reseating the CPU (checking for damage), reseating the RAM (testing each stick alone), and removing and reinserting the CMOS battery. Unfortunately, none of these attempts have allowed me to get past the POST screen or into the BIOS.
At this point, I'm concerned it could be a problem with the CPU, motherboard, or PSU. I don't want to start replacing parts unless I'm sure, but I also worry about how to troubleshoot further since my old components won't work with this setup. I'm considering RMAing the CPU, motherboard, and possibly the PSU, which still has some warranty left. Any advice would be appreciated!

Don't forget to check if your motherboard has a reset button for the BIOS! Sometimes, a simple reset can clear any settings that might be causing the POST to fail. Plus, while you’re troubleshooting, it's worth testing all connections too to ensure everything is plugged in correctly.
It sounds like your CPU might have died, especially since you're using an ASRock motherboard. My suggestion would be to RMA the CPU right away. If you can, try returning the motherboard too and consider getting a motherboard from a different brand, as they can sometimes be more reliable. You really want to get back to gaming ASAP!
I had a similar issue, and it turned out to be a bad power supply rather than the CPU or motherboard. Before you go through the hassle of RMAs, try testing your PSU first if you can. If it’s still under warranty, you might just swap it and see if that resolves the POST issue.
