How to Fix Windows PC keeps restarting after installing new GPU

If you are a gamer and need maximum performance, or your job involves running heavy graphics such as graphics design, then it is advisable to change your graphics card to a higher level. However, even after changing the graphic cards, some customers have complained. According to these customers, after replacing a new GPU, the PC keeps rebooting. In case this happens, here is a step-by-step procedure highlighted in this article on how to troubleshoot it.

Windows PC is constantly rebooting after the installation of a new GPU

Fix Windows PC keeps restarting after installing new GPU

If your Windows PC continuous reboots after installing a new graphics card, then try the following methods.

Un-plug the necessary components and then re-install the graphics card.

Clear CMOS

Install the GPU in another slot PCIe

BIOS update or BIOS Reset

Utilize DDU tool

Hardware malfunction

The following are the explanations in detail for all of these repairs. First, ensure that the GPU model you are on is compatible with your motherboard.

1. Refit the graphics processing unit and other peripherals, if any.

The first thing you need to do is reassemble the hardware, including the GPU. Place your graphics card in its slot properly and see all the wires connected to it. If the problem starts after you've assembled your computer, just reinstalling the CPU, GPU, and RAM sticks should fix it. Take each piece of hardware out of its slot and reinstall it again. Take a look at the CPU pins also, as if your CPU's pins are bent, then this problem can also arise.

2.Crystal CMOS

First of all, we need to clear the CMOS to move on with the solution. Clearing the CMOS is always a pristine method for solving any hardware issues. You first need to open the casing of your computer in order to approach the CMOS battery. This little battery is coin-shaped. After a few minutes, taking it out from the socket gently, replace the battery using the opposite polarity. Just power on your computer and see the magic for yourself.

3. Replace the graphics card's PCIe slot with another.

Another potential explanation for this problem is that the PCIe slot of your graphics card itself is the culprit. Perhaps the slot machine is defective or something. You can connect the graphics processing unit to any other free PCIe slot if your motherboard has a lot of slots and none of them are utilized. Just give it a shot and hope that it works. If it does, then the problem was with the port where you had initially attached your graphics card. You can have the motherboard replaced, provided your computer is under warranty, by contacting the support. Otherwise, you will have to take it to a repair shop that would replace the damaged PCIe slot.

4. Update BIOS or Reset It.

Because cleaning the CMOS resets the BIOS, you would not need to reset the BIOS if you have ever cleared the CMOS. If the CMOS has not been cleared, you are going to have to reset your BIOS. In case that doesn't work, try updating your BIOS. Go to your computer's manufacturer website and download the latest version of BIOS.

5. Make use of the DDU tool:

In case, the DDU utility can be used if the problem still persists. But this fix will require a reinstall of an old graphics card. For this fix with the installation of the old graphics card instead of the new one, you need to first turn off your computer and disconnect the new one if present, then reconnect it. Now, start your computer. The use of the older graphic card should not be problematic.

Download the Display Driver Uninstaller setup and open it. Follow the process, boot your computer into Safe Mode, and uninstall the old graphics card driver. You will finally remove your old graphics card driver from your computer. The option for DDU should be selected to Clean and shutdown. If this is selected, when the GPU driver uninstallation is done, your computer will automatically power down.

When it shuts down, replace the old GPU with the new one. Power up your rig. The moment you turn your rig on with your new GPU installed in it, Windows will install the correct driver for you.

It is in place to install a new driver after the current one has been completely uninstalled with the help of DDU software. This is very useful if you have built a brand-new computer and don't have the previous one.

6. Hardware malfunction

The power supply unit could be faulty. Can your power supply unit handle how many watts it takes for your graphics card? In that case, you replace it with a new one. Besides that, this problem could also occur due to a defective graphic card or motherboard. If you want diagnosis and repair of this problem, then you need to contact a computer hardware technician.

Using the above steps, you should be able to find and correct the reason for your quelling PC restarts after the new GPU installation.
