When I first plugged my power chord 6x multiple SCHUKO it gave my house a shortcircuit.
After 3 weeks working my PC got problems when playing games.
It froze or restarted randomly.
Once the whole PC would refuse to boot up, no fans working, just case lights.

I unplugged cable from the GPU and used integrated graphics while GPU still in the mobo but unused (fans working).
I put the PC to sleep and it woke up.
powercfg -lastwake said it was the PCI-E waking it up.
I unplugged the GPU and everything was working fine on integrated graphics.
I RMA the GPU and got a new one.
PC still freezes or reboots, restarts instead of shutting off.

I put the GPU out and I am now waiting for a new PSU because I thought the first shortcircuit could have damaged it.
Yesterday I realized my PC wakes up when lights of my room are turned on of off.
Today I understood that only happens when keyboard is plugged. It will not even let the pc turn off but it will cause a restart just after the switch off.


Now, what should I do?
What is/are the problem/s?


Tomorrow I will get a new PSU.
Do I need a surge protector? (Will it isolate the PC from other devices such as bulbs?)

Please help me I am confused and spent my money on a machine that is not working as it should.

PSU 450W XFX Pro Series
GPU Zotac 750 GTX ti
CPU i5 4460
MOBO H81M-HD3 Gigabyte

By short circuit, do you mean it tripped a breaker? Its possible you could be drawing too much current from the fixtures hooked up to that breaker.

Try plugging the computer into a different outlet in the house, not in the same room. See if that helps anything.

Sorry im not good with technical English but I mean light went off in my whole house and I had to go back to the central switch to bring it back on.
PSU is 450W, it shouldn't be too much on any wall, right?

Anyway that happened a while ago, the PC went on working for a while.

The problem now is that:
1) sometimes pc wakes from sleep when I turn the light on
2) sometimes pc restarts instead of switching off
3) I cannot connect GPU to my mobo because the whole pc freezes

Is this PSU's fault?

This might sound really stupid, but what country are you in?
I'm not familiar with your PSU but many PSu's have a switch on the back that dictates 110/120V or 220/240V ... is that switch in the correct position for your locale?
