I'm experiencing a frustrating issue where my PC keeps rebooting during games. It reboots repeatedly until it finally powers on again. All my components, except for the GPU, were purchased from reputable sources:
- RAM: Corsair Vengeance 8GB x 2
- CPU: Intel i5 12400F
- Power Supply: Corsair CV750
- GPU: RX6600 XT Eagle (I bought this from a seller on Facebook Marketplace)
I suspect either the GPU or the cooling setup might be to blame. Currently, I have two stock fans and an additional three molex fans installed, but I'm concerned they might not provide adequate cooling. The games run fine initially, but the rebooting issue can happen even in less demanding games. With more intensive games, it lasts about 20 minutes, and sometimes as long as 30 minutes; lighter games last 1-2 hours before shutting down. If anyone has suggestions or needs more info like logs or specific specs, please let me know!

Have you considered whether your CPU thermal paste needs renewal? Also, make sure to monitor both CPU and GPU temperatures while gaming to check for overheating issues.
This sounds suspiciously like RAM issues. When you start a game, it demands more RAM, and if there's a bad sector, it could crash the system. I'd recommend running a RAM check tool a couple of times since bad sectors might not show up right away. Alternatively, you could try swapping out the RAM to see if that resolves the problem.
I'll give that a shot and keep you updated.
Could using the wrong RAM slots (like 1,2 instead of 1,3) cause similar issues?

I did change the thermal paste once, and the temp during gameplay is around 75-80°C (about 167°F), which seems normal.
