Question My CPU and motherboard are completely damaged - what could be the reason?
Hello,
My i7-8700 CPU and MSI Mag Mortar B365M motherboard have completely failed recently. Anyone know what could have caused this? I attempted a check-up and troubleshooting to see if there was still a chance to fix it, but the CPU wouldn’t power on or show anything on an 8th/9th generation board. The motherboard also failed to start when tested with a working i3-8100 CPU.
At the time, I was installing a new game while playing Fallout 4. CPU temperatures reached over 90°C (with room temperature at 35°C and no air conditioning), and usage peaked at 95-100% across all cores/threads. The i7-8700 was cooled by a tower cooler (Thermalright Assassing King 120 -TDP 150W). The PC just shut down suddenly.
I cleaned the RAM, reinstalled everything, but it didn’t help. The PSU, GPU, and RAM seem fine since I’m using them on another machine. Any advice would be greatly appreciated to avoid another problem.
I brought a used 8th generation motherboard because I thought only the board was damaged, and since it was a cheap deal, I had no choice but to install a compatible CPU. (I should have checked it first before making such a decision.) 😊
PC Specifications:

Case: Thermaltake Versa h15 mATX
Check if it needs building. Is it brand new, refurbished, or used? Was it used for intense gaming, video editing, or mining?
I purchased a SeaSonic M12II 620 Bronze PSU in 2011. It worked fine for twelve years, even with moderate use. If the other person's PSU is also aging, it might pose risks when used. It wasn't a poor choice initially, but now it seems best to switch to a fresh one. As for what caused the CPU and motherboard failure, it's hard to say. If the system simply shut down to avoid overheating, damage could be possible. The cooler stopping might affect the CPU, but that doesn't explain the motherboard issue. Perhaps the CPU could suffer harm if the cooling fails, yet the motherboard still failed. It would be wise to bring the PC to a repair shop for a thorough check. Since you now have a new motherboard and CPU, consider getting a replacement PSU as well. A SeaSonic FOCUS GX 650 Gold would be a suitable option.
I purchased it in 2017 and have been using it exclusively at 1080p with a 60hz refresh rate. Back then, I used it for about 6 to 8 hours daily, but since 2020 I hardly use the PC anymore; it still functions properly up to now.
It's been six to seven years now, and that's all the use. Nobody knows when it was made, since it's extremely old.
This PSU was in good condition during its time. It might even function well now.
But it's no longer under warranty, isn't it?
Absolutely, it should be replaced. PSU parts don't age like wine—they deteriorate over time.
I still don't know what led to the motherboard and CPU damage.
yes definitely looking to replace this.
On where I live power isn't very reliable, we get power surges and low voltages. But I bought a UPS plugged into a surge protector.
Maybe hot ambient temps 35+C? I do not have an AC and the before this happened I am getting 90+C from the cpu on games like Cyberpunk, maybe the vrms couldn't handle the heat, the old psu and the power hungry i7-8700?
