If your PC restarts when playing games, try these proven troubleshooting ideas right now!

Unexpected restarts are every gamer’s nightmare. Hours of hard-won progress vanish in an instant, leaving frustration and defeat. If you’re a pro streamer, it’s even worse.

Since I’ve faced the same ups and downs, I’ve set out to find the best fixes and list them in an easy-to-follow language. Let’s get into it!

Basic Checks and Fixes
• The internal components have likely heated up a lot. Let the whole
device cool down
• and try to put the PC in an air-conditioned room or well-ventilated area. Remove all detachable accessories, like external game recording devices, removable storage, USB hubs, gaming steering wheels,
game controllers
• , etc. Restart the GPU by pressing the Windows Ctrl Shift
B
• keys at the same time.
Power cycle the PC

by shutting it down, removing all cables, and pressing the power button for 30 seconds.

If the above tricks don’t help, continue with the more detailed troubleshooting ideas outlined below, starting with the simplest ones.

Restore GPU Console Settings

Both NVIDIA and AMD Radeon allow you to customize how the GPU resources are used globally and for specific apps. If you’ve personalized those settings, undo that by following these steps:
1. Right-click on the Desktop and click on the GPU configuring console tool, like
NVIDIA Control Panel
2. . Go to the Manage 3D Settings menu under the
3D Settings
3. tree. On the right side, go to the Global Settings tab and click on
Restore

.

4. Now, go to the Program Settings tab, select the game you played when the PC restarted abruptly, and click Restore.

5. Close out the NVIDIA Control Panel tool and reboot your PC.

Increase Virtual Memory

1. Right-click on This PC or Computer in the Desktop or Start menu.
2. Select Properties to open the About PC window.
3. Scroll down to the bottom and click on the Advanced system settings.

4. This should open the System Properties dialog box.
5. Click on the Settings button in the Performance section.

6. The next dialog box that opens is Performance Options.
7. Navigate to the Advanced tab.
8. Now, click on the Change button in the Virtual memory block.

9. You should now see the Virtual Memory dialog box.
10. Select the drive where you’ve installed the Windows 10 or 11 OS.
11. Click on the Custom size option and enter the following values in the respective fields:
    • Initial size (MB): 2,048
    • Maximum size (MB): 5,000 or 10,000 (Depends on your SSD or NVMe SSD chip’s total storage capacity and what’s left after installing the Windows OS and other apps.)
12. Click on Set, OK, and hit Apply on every dialog box to save the changes.

Update the BIOS

If the BIOS firmware of the motherboard is too old and you’ve installed many modern hardware recently, the mainboard won’t be able to communicate with the newest additions appropriately.

This condition aggravates when you play a resource-hogging PC game and the system restarts to prevent internal damage.

So, you must update the BIOS firmware to its latest edition by following these steps. I’ve done it on a Gigabyte B660M DS3H AX DDR4 motherboard. The steps are similar across manufacturers.

1. Visit the mainboard manufacturer’s website to download the latest BIOS firmware.
2. For Gigabyte B660M DS3H, here’s the official source.

3. Download the latest release. Look at the F-ID, like F30 and date of publication.
4. Extract the contents and move them to an empty USB stick.

5. Keep the USB stick plugged in.

6. Restart the PC.
7. Press the Delete button repeatedly.
8. You should see the UEFI BIOS interface.
9. Go to the System tab.

10. Click on the up-arrow pop-up box at the bottom of the screen.
11. Select the Q-Flash option.

12. Go to the Task tab of Q-Flash.
13. Click on the Update BIOS option.

14. The system will automatically pick up the updated BIOS firmware in the USB stick.
15. Simply click on the file name to initiate the file verification and click on the arrow on the right edge of the screen.
16. Click on the prompt to start the updating process and wait until the PC reboots.

Before attempting this method, connect the PC to a stable power source. If the power fails during the BIOS updating process, your mainboard will get bricked.

Disable CPU, GPU, and Memory Overclocking

If you’re overclocking your system to push it beyond its limits, you should stop, especially if the PC restarts when playing games. Here are the steps if you’re using the hardware diagnostic tool MSI Afterburner:

1. Open MSI Afterburner.
2. Set the configurations for the following components as outlined below:
   • Core Clock: 0
   • Power Limit [%]: 100
   • Memory Clock: 0
   • Fan Speed [%]: Auto or 41
3. Click on the Save button.

1. Reboot the PC.

Reseat All the Removable PC Hardware

It’s time you open the CPU up and reseat the removable hardware by following these steps:

1. Shut down the PC and unhook all the cables from it.
2. Wear an anti-static wristband and connect its metal clip to another grounded conductor, such as an alloy hook embedded in the wall.
3. Alternatively, just touch a grounded metal body and wear an insulated shoe.
4. Now, remove the left side cover of the CPU case.
5. Use a screwdriver when needed and carefully unplug all the cables inside the PC case.
6. Remove the following components from their slots:
   • GPU card
   • RAM chips
   • SSDs
   • M.2 NVMe SSD chips
7. Now, clean the motherboard with a blower, a clean paintbrush, or a clean cotton cloth.
8. Put back all the hardware and cables in their respective slots and ensure they fit snugly.
9. Connect all the PC cables, power it up, and play the same PC game that showed the restart issue in the first place.

Download and Install the Latest DirectX Runtime Package

1. Visit the DirectX End-User Runtime portal.
2. Hit the Download button.
3. Double-click on the dxwebsetup.exe file.
4. Accept the agreement and click Next.

5. Uncheck Install the Bing Bar on the following screen and click Next.

6. The installer package will start updating the DirectX version.
7. Click Finish when done and reboot the PC.

Run the Windows Malicious Software Removal Tool

Certain malware might have infected your device to silently use the resources for crypto mining. When you play a PC game, the system restarts to prevent it from causing further damage.

Here’s how you can detect and remove such programs:

1. Download the Windows Malicious Software Removal Tool from Microsoft for free.
2. Go to the Downloads folder and double-click on the Windows-KB890830-x64-V5.129.exe file.
3. It doesn’t require any installation.
4. The app interface will open right away.
5. Click Next.

6. Select the Full scan option on the next window and hit Next.

7. The malware scanning and removal process will begin.

Update all Hardware Drivers

1. Open the Device Manager interface by pressing the Windows X keys.
2. Extend the tree for the Display adapters, right-click on the GPU, and select Update driver.

3. Choose Search automatically… on the next screen.
4. Now, repeat the same steps for the rest of the hardware components, like Audio inputs and outputs, Monitors, Wi-Fi Network adapters, etc.
5. Restart the PC when it’s done.

You might not be able to update everything easily by following the above steps. You can get the PC HelpSoft Driver Updater for a more convenient, one-click experience.

Update the Windows OS

1. Press the Windows I keys together to bring up the Settings app.
2. Click on the Update or Update & Security menu.
3. Select the Windows Update option on the left.
4. Hit the Resume updates, Check for updates, or Download and install updates buttons.

5. Once that’s done, come back to the Windows Update window.
6. Click on the View update history link.

7. Expand the following trees and apply all:
   • Driver Updates
   • Definition Updates
   • Other Updates

8. Restart the PC if it doesn’t do that itself.

Increase the Wattage of the PSU

Your power supply unit likely can’t deliver the required power for high-end games, leading to transient spikes during map loads, character rendering, or other high-resource scenarios.

So, get a genuine PSU that delivers 800 watts and more power, especially during those spike moments.
