Hello, I want to apologize in advance for possible posting in a wrong thread, but I failed to find an altogether PC thread.
Approximately a month ago I started having issues with my PC that won' suddenly turn on after I shut it down.
It just works perfectly fine, without any issues, all the temperatures are normal and stable, no crashes, no BOFD, everything is just fine, then I turn it off the way it's supposed to be turned off and it does turn off without any weird sounds etc. Just perfectly normal.
Then the next day, when I want to use the PC it just won' turn on.
I have to take it all apart, bit by bit, unplug everything, then put it all back together and then it all magically starts working again, no issues, nothing.
Rinse and repeat.

But today I am facing a bit different problem, it won't turn on no matter what I do.
It was working perfectly fine yesterday and today it won' turn on again, after I took it all apart and then put it all back together, it won't turn on.
I have no idea what the problem might be and Iam lost in ideas.

My specs:
Motherboard: ASRock 990FX Extreme3 - AMD 990FX
CPU: AMD Phenom II X6 1090t 4Ghz (OC)
RAM: A-DATA XPG Gaming Series 8GB (2x4GB) DDR3 1600
PSU: Fortron AURUM 600W
HDD 1: WD Caviar Black 7200RPM 500GB
HDD 2: Seagate Barracuda 7200RPM 320GB
GPU 1: GIGABYTE Radeon HD 6870
GPU 2: Sapphire Radeon HD 6870

Please help :(

Try this.

If the Psu has a rocker switch on the back of it turn it to its off state.
Flick the switch off at the wall that has the cable for power going to it to the back of the PSU.

Count ten seconds.

Turn the switch back on at the all socket.
Then flick the rocker switch on the back of the Psu back to its normal state.
If you press the power button on the tower and it fires up.

Then what it is saying is one to three things.

A: one of the protection circuits of the Psu is faulty.
B: You may have an over, or under volt of supply by the psu.
C: Short circuit protection is kicking in on the Psu.


All of the above will Isolate power from the Psu to the board and components.

It is AeroCool Strike-X ONE Black and I've got it since this christmas. I doubt it is the switch because this problem occurs also when the PC is in a sleep mode and should be able to be turned on also by pressing a key on the keyboard or by moving the mouse, but the PC just does nothing.

Unfortunately we don't have those switches on our power outlets.
Switching the ON/OFF button on the PSU doesn't change anything.
I think I will have to buy a new PSU, this one seems totally dead :(
And I though it was a good one.

EDIT 2: Just plugged it into the motherboard (CPU + RAM only) and voila, it started magically working again.
And Iam getting seriously frustrated, I know this is going to happen again, so please, if anyone has any idea of how to fix this, please let me know.
