No power from PC after electric surge

vygec · 1 Oct 2009 at 20:36

The electric went in the whole house. since then the PC, wont switch on. ive opened up the case, disconnected the CMOS battery and unplugged the power from the PSU to the motherboard. left it for a minute or so, and plugged all back in again, no change

Anything else i can check, or do i have a busted PSU!!

Ta.

i tried a different power lead, and plugged this straight into the mains. this had no effect either

Could try removing all power leads from the pc, plug a fan into one of the molex connectors and link out pins 13 & 14 on the main 24 pin ATX connector, switch the power on the power supply or mains socket and see if the psu starts.

just an update, i just tried this. the fan powered up!
however when i plugged everything back in again, no response from the unit.
does this mean that the psu is ok?

hmm..what do i do, never used one, what to connect where and do what, and what am i looking for?

someone please help!
i picked up a new psu (corsair hx650), just plugged in with the same result as before.. no response from unit. ive only plugged in a hdisk, and discarded everything else, but no response.
any ideas on what is causing the problem, im wondering whether its the mainboard now?

update, no idea how this happened..
but i got a different mainboard/cpu from a friend. plugged in, this worked fine, so disconnected, and connected all my original components, and now they too are working ok!
again, i have no logic to what caused this, however its working, i will keep an eye on it though!
