Question Please help, system won't turn on ?

[Ros2000]

So today i was playing CSGO and once i tabbed out my screen flickered in white for maybe 15 seconds. I decided i was going to try a restart. I restarted it and upon turning back on i was presented with my fans and leds all working but the DRAM and CPU red leds were lit up (not flashing, just a solid light). There was no beep or anything just no signal to the screen. I have tried the cables it hasnt worked. I also tried both my ram sticks they seem to be fine.

Please help, here is a video of what happens.
