Hello, I'll start from the beginning and include all my parts. I bought all these parts 2 weeks ago.

I5 4670k
MSI Z87-G45 Motherboard
GTX 770 4GB (from Gigabyte)
800W Silent pro gold power supply
8GB Corsair RAM
The computer was working fine for about 5 days until I noticed that the monitors HDMI was flickering on and off. I returned the monitor for a new one yesterday and it flickered again today. Heres where my computer really gets completely rooted. After trying so many things to fix it its insane, I read a thread that recommended booting into safe mode, uninstalling all graphics drivers, inserting my disc and reinstalling the graphics driver from there, and then rebooting. I did this, and this is the point that my new $1500+ PC died. It turned on and the screen started going crazy, flickering like mad every half a second, and refused to turn off when I pressed the button or held down the button, I ended up having to flick the switch at the back so it would turn off. Now it doesnt turn on at all, I've turned the switch back on and tried to boot it up, nothing.

I'm completely freaking out, I don't know whats happening.
Does anyone know what I can do?

EDIT: I took out every part in there and rebuilt the computer, its working. Still waiting for the original flicker but its a relief that it turns on and displays now at least.
 
Ok, I`m going to try to explain this.

On the back of the power supply is the rocker switch.

Now the Psu has over voltage protection, and a few other protection circuits built in.

To reset the circuits, you turn the rocker switch off.
Turn the power off the cord from the Psu to the wall is plugged into.
Give it about a ten second count.

Turn it back on at the wall socket switch. and then the rocker switch to on at the back of the psu to reset the protection circuits.

Your flickering may be because you have not defined what is the primary default graphics display out put card. Meaning your GTX 770 card in the Pci- slot of the board.

As the board also contains or has on board graphics.
If you can, disable the on board graphics in the bios.

Set the first graphics device to be initialized in the order list to Pci-E by manually setting the value. do not leave the board set to auto in respect to graphics settings.

Save the new settings before exiting the bios.
The screen flicker should go away.

If you are still stuck with flickering replace the Hdmi cable being used.
And check that the screen resolution is set right in windows for the monitor you are using. Also make sure or check what Hz range at the resolution you have should be set.
Hz syncs the image to the screen, if it higher than the monitor can cope with, from the signal the Gtx 770 card is sending it will A:Flicker. Or B: say signal out of range if the Hz range is set to high.

Over scan can often be the cause because as you stretch an image to the screen it increases the Hz signal sent to the monitor so the resolution can fit the screen display.

To far over and the screen will flicker.
