Motherboard (78LMT-USB) and processor (AMD FX6300) have died TWICE

I've just AGAIN found that my motherboard (78LMT-USB) and processor (AMD FX6300) have died.

I haven't overclocked, all I did was use it for a full day and night. Then the next morning - no power at all.

I tested the PSU, memory and case and they work fine. I replaced the motherboard and CPU and it was fine again (until it went AGAIN) today. I had to replace both the CPU and Motherboard as it didn't work though with the old cpu in the new motherboard or vice versa.

I tested the temperature all day and it hovered between 20 and 50 degrees - even when gaming.

Now when I try to turn on the PC - nothing! No lights, no power, no fans. Just completely dead (I suspect until I replace the motherboard and CPU).

Any thoughts on what has caused this and how I can avoid again?

  1. Sounds like your PSU is killing those parts. Maybe try a different PSU?

    It's not a fire hazard PSU buts its still a low quality unit with little protection circuitry. It could be failing and killing other parts.

    This list is a little old but it supports what I'm saying.
