Solved: Display keeps turning off

Hey Everyone i am having a serious problem with my computer.

Specs:

Motherboard: Asus Z87-PRO
Ram: 4x 4GB (16GB)
Processor: Intel Core i7-4770 CPU @ 3.40 GHz
Windows 7 Home Premium (64 bit)
PSU: Cooler Master Gold 800W
Video Cards: 2x Radeon R9 - 290X
HDD: 2 x 1TB


Everything runs fine in Safe Mode.
Outside of safe mode, My computer runs fine if i don't touch anything... The moment I open a folder, browser, Task Manager, or anything at all, the screen glitches for a second and turns off the display. Nothing can be done and the only solution is to do a hard reboot which has become a perpetual problem.

I should also mention this is a litecoin mining rig.

Everything was working fine until my computer was mining and randomly shutting down completely after some time, the cards were not overheating and hovering around 83 degrees celcius.

Now It won't even go beyond opening an application.

Can someone please help me with this issue.


Thanks.
