@Aarav17 -- it might be overheating of the video-adapter in your computer, causing it to stop sending output to your screen. How warm/hot is the air being exhausted through the vents in your computer's case?

@Aarav17 / @Niket08 -- how old is your computer?  If it is a few years old, and it "lives" in a dusty environment (cat or dog hair), then you could try:

1. shutdown the computer
2. disconnect the power-cord
3. for a laptop, remove the battery
4. hold-down the on/off switch for a few seconds, to drain any "residual" power
5. for a laptop, take a can of compressed air, and shoot into every intake/exhaust port, to try to blow-out any accumulated dust
6. for a desktop computer, remove a side-panel, and use a can of compressed air, focusing on the blades of the fan on top of the heat-sink on top of the processor, and on the heat-sink itself, and, if present, on the blades of the fan on the "inside-back" of the computer's case. Also, shoot air into all the vents of the power-supply.  If you see any dust on the edges of the fan-blades, gently remove any dust. If your computer has an add-in video-card, there might be a fan on that card. Shoot it, too. Also, check that every fan spins freely -- no seized-up ball-bearings.  After, while you can still see the fans inside the case, reconnect the power-cord, and power-on the computer, to confirm that the fans do spin. After a few seconds, disconnect the power-cord to cut the power to the computer. Replace the side-panel. Reconnect the power-cord. Start-up the computer, use it for 10 minutes, and again measure the temperature of the warm air.

If step #6, above, exceeds your comfort-level for "tinkering" with the computer, then remove the side-panel, and just look for dust. Then, replace the side-panel, and take the computer to a computer technician, for them to do the physical "cleaning".

I hope this helps.
