Hey everyone! I'm having a frustrating issue with my PC where it keeps shutting down and rebooting, regardless of what I'm doing—whether I'm just browsing on WhatsApp or gaming. It usually lasts less than 15 minutes before restarting. The highest temperature my processor hits is only 50 degrees Celsius, so I'm not sure what the problem is. I've already tried swapping out the motherboard, but the issue still persists. Here are my specs: 8 GB of Samsung DDR4 RAM in Dual Channel, an Intel i5-9400F, an MSI Z390-A Pro motherboard, a 2GB VRAM GTX 1050 graphics card, and a Corsair VX550W power supply. Any ideas on what might be going wrong?

My PC used to do that too, but I found out it was overheating. Are you sure your cooling system is adequate? Sometimes dust buildup can cause issues, or maybe the thermal paste on your CPU needs replacing.
Have you checked the Event Viewer for any errors that might indicate what's going on when it crashes? That could give you some clues about the issue.
If everything checks out, it could be a power supply issue. Even though it's a Corsair, sometimes they can fail and cause random reboots. Consider testing with a different power supply if you can.
