How to Stop your PC Restarting after Installing a GPU (STEPS)

Can GPU cause a PC to restart?

Yes, a GPU can cause a PC to restart. This often happens due to an overheating GPU, incompatible drivers, dry thermal paste, or a loose connection.

The restart can also occur due to a missing supplemental power connector from the PSU to the GPU or an overclocking graphics card.

  • Overheating GPU
  • Incompatible drivers
  • Dry thermal paste
  • Loose connection
  • Missing supplemental power connector
  • Overclocking graphics card


Overheating GPU

There are chances of the PC restarting if the GPU is overheated. The heating may be because the GPU is dirty or its fans have broken blades.


Incompatible drivers

If the graphics driver installed in the PC isn’t compatible with your GPU, the PC may restart. This could be due to a version mismatch or a substitute driver that triggers the restart.


Dry Thermal Paste

The PC may restart if the thermal paste on the GPU has become dry or hardened. This tends to happen over some time.


Loose connection

A loosely seated graphics card or processor can result in a PC restart. Similarly, a loose cable connection can also pave the way for a restart.


Missing supplemental power connector

The PC is likely to restart if the power connector from the PSU to the GPU is either loose or missing.


Overclocking graphics card

The graphics card can get overclocked when it’s overloaded. The overclocking can cause the PC to restart for protection against damage due to overload.


Why does my PC keep restarting after installing GPU?

Your PC may be restarting after installing GPU because of a graphics card setting, an overheating problem, the graphics card is defective, graphics drivers mismatch, or a power setting. 


You can try the following steps to fix the PC restarting problem after installing a GPU.
