today my computer worked perfectly, but suddenly mouse, keyboard, camera stayed without power, process coutinue to work in background. i restart and nothing. sometimes i couldnt turn on coumputer, it just make some strange noises. i change power socket and plug it into other and it turned on, everything works, but sometimes computer turn off by itself. is that to my computer, power supply, instalation in house or local power distributor?
that happened to me before, one day it turn off by itself and then months works perfectly. im desperate.
