Hi everyone,
I'm experiencing a problem with my computer. During gaming, monitor shows black screen and "No Signal-Analog" displayed. Whenever I experience this issue the screen goes black and glitches heard at the speaker (Part of game audio repeated or some creepy noises etc..). At this point of time if I restart the PC it will boot but black screen will appear. In order to get the proper display I need to cut the power and boot the PC again.


Games which I have tried are mentioned below:
Minecraft
TF2
FIFA 15
FAR CRY 4
WATCH DOGS


In my observation CPU Idle temperature is 25°C and during the game play it will reach around 36-40 °C max and GPU Idle temperature is 41°C and during the game play it will reach around 60-64°C max. After reaching the GPU max temperature i.e. 64°C within 2-3 minutes of gaming monitor shows black screen and shows "No Signal".


It is observed that the issue occurs fast If I play game at Ultra Settings.


I tried the below changes and still the issue keeps recurring again.
Changed the GPU to another GTX 970.
Did under-clocking the GPU by 100Mhz
I also have a dual boot system both OS crashed on me aswell.
Increased the fan speed to 100% with the help of MSI AfterBurner
Decreased the Power limit settings to -10% and did tests again on stock clock and under-clocked condition
Tried different version of the Intel drivers and Nvidia drivers i.e. The driver comes with the bundled DVD, Latest drivers, Previous versions of drivers etc..


At this point of time I'm really in trouble because I can't play any games more than 15-20 minutes.


Please suggest me:
What could be the possible reason for this issue?
How can I rectify the issue?
Thank you in advance for your help and advice.
