Monitor display went off, but CPU remains running.

Ok, I have searched the internet for a solution and like an illness, there are many theories for this. Also, if there is a similar thread to this, go ahead and delete this and redirect me to that thread.

Recently, my PC has been behaving strangely. Under graphical load (playing Dota 2), my computer display will go off suddenly. No, it is not my monitor because it says "No display detected". This means that the monitor is still receiving, but nothing is transmitting images anymore. This lead me to my GPU.

Before that, this is my specs:

  • i7-2600
    Asus P8z68-vlx
    4x4GB DDR3 1600MHz Corsair Vengeance RAM
    Leadtek GTX 580 3GB
    Corsair TX750M PSU
    120GB Corsair Force SSD
    1TB WD Blue
    4x 120MM Fans
    2x 140MM Fans
this system is 3 years old

As far as I know, my GPU is working fine. But this is purely an assumption, because when I am about to tell you will probably make sense.


    - GPU overheating: Little chance having that happen with my 6x cooling fans
    - My hypothesis is that when under load, the GPU draws more power from my PSU
    - My PSU, unable to cope with the extra load, cuts off power to my GPU, thus resulting in a no display; running cpu situation
    - When I'm surfing internet, nothing like that happens.
    - Nvidia Driver problem probably isn't this inconsistent (like act up with its under load and don't when its not)
    - Not to mention, the power consumption of my 6 Fans, WYSE antique keyboard and a logitech mouse is going to put a load on the PSU


When do you guys think? I wouldn't mind spending 150 bucks on a new PSU.

I forgot to add. Last week I ran into a severe driver problem. It was so bad my computer goes into Blue screen every time it boots up into the windows desktop. I ended up reformatting my C: and reinstalling the driver directly from my Leadtek disc. I did not update the driver as the newer Nvidia drivers have already caused me pain so great I'd rather give birth. It works fine with the old driver until yesterday when I was on Dota 2. I played for nearly 1.5 hours before the problem started.
And I dare not update the drivers. It is like "Driving a Maserati down a dead-end street".

@Presler Well, I am pretty sure if the game files are bad, it wouldn't kill the display but instead, it will show some error on the screen. A GPU problem can be a factor though.
