Optimize your GPU Temperature
When you are gaming or performing heavy work, the GPU of your system heats up quite a lot. It is quite common for a laptop’s GPU to overheat and cause the problem of the black screen.Most laptops shut the GPU down when its temperature rises a lot. But sometimes, along with the GPU, the monitor may also be unresponsive. This can also happen when your system receives an abnormal power supply.You should check if your laptop runs well after the GPU cools down. If it does, then you should look towards optimizing your GPU temperature. Firstly, you should not use your laptop on soft surfaces such as beds or mattresses and instead use hard materials such as books that support the dissipation of heat.The best thing to do is to use a cooling pad under your laptop. Similarly, if you have overclocked your graphics card, then it raises the GPU’s temperature quite a lot. You should revert the settings as well as lower your in-game settings.One of the best ways to lower GPU temperature is to undervolt it. Undervolting reduces the overall power consumption by the graphics card, hence lowering the temperature. We have prepared a comprehensive guide for undervolting the GPU safely.These advanced mentions are a surefire way to reduce your GPU temperature and bring forth a little more stability.
