First suggestion is try a known good power supply, it may appear to be working but as PSUs put out varying voltages +3.3V, +5V and +12V any one of these may be faulty and cause issues such as what you are getting 2nd Try each stick of Ram individually (do the same with the GFX cards) and 3rd as an outside chance try clearing the CMOS by removing the CR2032 battery on the MB and then replace it, reset the time and date in the BIOS if you get your screen back.
Leave the side off your case when you do your 1st test so that you can make sure all fans are working correctly.

You know what, when I had my ram problem, another guy here tested my psu and one of the voltages was faulty he said. I couldn't afford another psu at the time after building that expensive PC so I kept that one in there. It will take me a day or so to get a hold of another psu I can try. Thank you.

Ok, it is not worth chancing any other tests just in case the PSU is bad and goes bang.
I will look out for an update when you are able to try the other PSU.

I just got my brand new corsair psu in and the PC does the exact same thing
I noticed the top fan wasn't spinning also so I unplugged the power from it and turned it on again, still the same thing.

I tried the 2nd step and tried each video card one at a time. Bingo. The card in the main slot is faulty. I'm now going to check if I'm still under warranty for this card, it's only been 7 months, so I am hoping so. Thank you so much for your help.
