Hi guys, build specs:
Amd fx 8350 Black edition
Gigabyte fxa990 ud3 mobo
Gigabyte Hd Radeon 7870 gpu
Antec Kuhler 620 water cooler
Corsair 750 Tx PSU
WD Blue 1 tb hdd
G.Skill 2x 4gb Ddr3 RAM
G.Skill 2x 8gb Ddr3 RAM
DeepCool IceBlade x 4 Led fans
1LG Dvd combo drive
LG 41" Flatscreen LCD with HDMI cable

Yesterday, everything was working fine. Suddenly on my monitor screen, there was a pixelate disturbance. Multi coloured pixels all over. Only the mouse was visible and the rest everything was just a billion pixels. Then it turned into vertical lines of green, yellow, brown and white.
After a minute, the display was gone.
No beeping sound too

I don't have any display port on the Mobo to test
There's no beep sound even without RAM or connecting different RAM sticks individually in specific slots

Everything seems to be working, including the GPU fans and Water cooler, fans, Dvd, etc. But NO display.
Sidenote: The monitor works fine because I am able to connect other devices to it and watch stuff
I am confused and very much concerned. Please help

if monitor works fine on other devices then unlikely a monitor issue as I suspect you have a bad videocard. try that card on another computer even a friend's for testing purposes to see if still have that issue or not.

Turned out to be an issue with the PSU, I replaced my PSU with a Corsiar 750 Watt
CX750M

As a result an ICE on my Graphic Card was fried due to the PSU issue (maybe Earthing problem)

I replaced the Graphic card and the PSU
