weird problem after power outage
after a power outage due to using together oven,pc and other domestic appliances(...)i've not being able to power up my pc,
i've tried everything,everything,pushing the startup button doesn't give any life signal unless:
i unplug the pc till mobo lights get off,replug,push power up button,
every time i'm just able to see the mobo lights up for a sec,then turn off,then light up again for an other second then turn off completely and....is gone.
sometimes,1 on 50,like now i'm writing,the procedure start up the pc and it works,until i turn off the pc,then it won't boot up again.
is it psu problem 100?
i doubt it just because:
i've tested it with psu tester and all is ok,
all pc is attacked to a multiple socket with surge protection and it still works,so ireally dount that just a power interruption can damage the psu this way,
also is not a cheap psu(850W Seasonic Prime Platinum).
thank you for your replies in advance.
