Hope one of are tech wizards can help with this cause I am stumped.

Changed my gfx on Saturday and PC was running sweet. Came down this morning to find one of our fuses had tripped cutting power to downstairs. I flicked the switch back and turned on the TV and kettle etc. I then sat down to read my emails hit the power button on my PC and nothing totally dead. Took the panel off to check all the connections and they are all how I left them. Tried the kettle lead and that's all fine so I looks like the PSU died. However how can this be as my PC was shut down last night and there was still power when I went to bed.

Here's the spec

Eermax Noise Taker 600W PSU
Asus SLI Deluxe
AMD FX-53
2x 80gb SATA Hard drives
2gb Geil RAM
XfX 7900 GT
6x fans

I am sure the PSU has enough grunt to supply this set up. Any help would be great
 
do you use power surge plugs to protect your pc in case of these kind of occurences???...

even tho your pc was shutdown I am assuming it was still plugged in etc which means when your fuses tripped it may have taken our your mobo or ** psu.....i am purely guessing btw....

have you tried resetting the CMOS?

when you turn your pc on does the psu fan spin?

are there any lights on your mobo and do the fans and hsf fan spin? tho they would even if your mobo was dead...

IMO you have enough juice there....
 
yeah I have a surge protector and the pc was pluged in as normal, the mother board does have a green LED that lights up when there is power but that isnt on and when I press the power button nothing happens. The thing that gets me is my G/F's pc is right next to mine and her's is happy as larry with out a surge protector.
 
Can you plug her psu into your comp and check or plug your psu into hers. The more you test the more you can eliminate. Sounds like psu if it tripped house mains but weird that theres still a green light on motherboard
 
Can you not just quickly try her PSU to give a final answer?

Nothing should have happened when the power is cut, but there would be a surge when it comes back on again. I normally take power cords out of the wall if this happens to me before I flick the appropriate switch in the fuse box. With a surge protector this shouldn't happen but cheap ones do virtually nothing in my experience anyway.
 
yeah I will swap psu's when I get home from work. Sorry for the confusion the I have an LED on my mobo to show power but this is not on even when PSU is turned on.
 
Sounds like a dead psu then or a dead board. Try the other psu and if you get a light on then that should tell you if psu is dead or not - might want to do it when gf not around in case hers breaks as well - that way you can say power was off again and your pc is dead as well
 
Don't forget to try a different mains lead as well, it might just be the fuse in that which has blown.
 
Its worth trying a full factory reset.

Remove Power connector from the motherboard, remove battery from motherboard, move cmos clr jumper to the clear/erase position.

Wait 10 minutes, then return the jumper to the normal spot, replace the battery, and reconnect the ATX power cables.

Then try and power up. Surprising how often this can help.
 
Well tried my G/F PSU and all is well so using a spare Jantech 500W one at the mo until my Enermax gets fixed under guantee.
