My Lenovo ThinkCentre Mini M9P3 suddenly stopped booting. When I press the power button, only the power LED lights up, the fan spins for a moment, and then the system shuts off before repeating the cycle. It did boot once, but after I launched Minecraft the display began showing a serious graphical problem, and the computer has refused to start normally since then. I have already reseated the RAM twice. I previously had two memory sticks, but one stopped working, so the system currently has only one installed.

The symptoms could point to a RAM problem, a graphics-related hardware fault, or another component triggering protection shutdown. Since you only have one memory stick, try it in each available slot and make sure it is fully latched. If possible, test with known-good compatible RAM. Also disconnect unnecessary drives and USB devices and see whether the behavior changes. If the machine still powers off immediately, the motherboard or power circuitry may be at fault.
The graphical corruption after launching Minecraft is concerning, although this model normally relies on the processor's integrated graphics rather than a separate graphics card. The display issue could still have been caused by faulty RAM, since integrated graphics use system memory. Try booting with the minimum hardware connected, check the monitor cable and display output, and see whether you can reach the BIOS. If it cannot remain powered on even before showing anything, focus on RAM, the power supply, and the motherboard rather than Minecraft itself.
I only have one working RAM stick, but I’ll try it in the other slot and test the system with the drives and USB devices disconnected.
