I'm struggling with my recently purchased PC and need some help figuring out what's causing it to crash. Here are the specs: Gigabyte b650M C V2 motherboard, Ryzen 5 7600 CPU, Zotac Gaming GeForce RTX 4060 with 8GB VRAM, 2TB Western Digital Blue NVMe SSD, and 16GB of T-Force DDR5 RAM. The seller mentioned possible issues with corrupt or missing files, leading me to suspect either a faulty motherboard or a bricked OS. I've updated the BIOS and reinstalled Windows multiple times using a fresh USB, but the PC continues to crash unpredictably, often showing a black screen with the error message 'CRITICAL_PROCESS_DIED (0xEF)'. Initially, it was overheating, but after installing a Noctua CPU cooler, temperatures are normal. I've formatted the SSD multiple times, but the crashing persists, especially when downloading games or changing graphic settings. Any suggestions on diagnosing or fixing this issue would be greatly appreciated!

It sounds like there might be something wrong with the RAM. A good first step is to test each stick one at a time if it's 16GB total. Sometimes incompatible or faulty RAM can cause these issues. If you're able, running Memtest86 could give you more insight into any RAM problems. After that, check if your motherboard is fully compatible with the RAM sticks you're using, as not all RAM plays nice with all motherboards. If the RAM checks out, the next easiest thing to troubleshoot is the GPU. Swapping it with a known good one could help narrow down the issue.
It could be a bad motherboard channel or CPU hiccups too. If you've formatted the SSD and it still crashes, definitely focus on RAM first. Try reseating the RAM sticks, especially if you have two of them. Sometimes just moving them to a different slot can make a difference. If that doesn't help, it's time to consider swapping parts out to identify the problem. It can be a pain, but we’ve all been there!
Definitely try booting into Safe Mode to run System File Checker and DISM. Those tools can fix system files that might be corrupt. But honestly, I suspect it’s more likely a hardware issue, especially since the crashes continue despite reinstalling Windows. If your RAM is confirmed to be incompatible by your motherboard's specs, that's a huge flag. Beyond that, make sure to monitor temperatures with HWMonitor to rule out overheating components. When it comes to troubleshooting, working with one component at a time is key.
