I have bought a computer from my friend. He had no problems with it for many years. I downgraded from windows 10 to 8.1, wiping everything clean. After 4 days of use the pc turned off without a warning and rebooted. After 3hours the pc did the same thing. And this keeps happening every 1 or 2 days.
I have tested everything. Power supply cord, memory, cpu,hard drives, all temperatures.I did all kinds of stress tests and the pc is running fine. Everything is working perfectly, but it shuts down randomly and i dont have a clue why. The last thing i can do is test the voltage with a multimeter, but i dont have one.
Before i started using the pc i installed a bracket to mount the cpu fan, because my friend didn't have the time to do so. That is it, i didn't touch anything else. If i didn't connect a cable properly the computer probably woulnt be running fine.
I am out of options, maybe this forum would help.
