Frequent Blue Screen of Death (BSoD) while Playing Games on PC – How to fix it?

BSoD stands for Blue Screen of Death or Blue Screen Error, also known as a Stop Error or a bug check. It may be caused either due to any hardware failure or any software issue. Upon encountering a critical error, of a non-recoverable nature, an error screen is displayed by the Microsoft Windows family of operating system that causes the system to crash. If there are frequent BsoD on your PC, then you need to follow the steps described below.


Firstly, remove all the recently installed software on your PC, as they may contribute in the system crash.

  1. Remove Gaming Tools like Daemon tools, etc. and disable Verifier to test. Some gaming tools are not good with Windows 7 and had known problems with Windows 7 OS and this may be a contributing factor in the system crashes.
  2. To disable Verifier, go to Start Menu then to All Programs and to Accessories. Navigate to command prompt and right click on it and Run as administrator. On entering into it, type verifier /reset command and then hit Enter.
  3. Restart your computer to make effect of the changes.

Upon restarting verify whether further BSoD occurs or not.

System crash due to bad memory

To verify, if the memory is working properly or not, run a memory test. The boot version of Memtest86+ is a better one to check the PC memory. Run the test for at least 7-10 passes or more or until errors show up.

If the error list keeps on extending then stop the error test and try the next procedures described below.

  • Shut down and turn off your computer
  • Unplug all power sources to the system, unplug the power from the outlet or surge protector or PSU, if it is a laptop then remove the battery
  • To drain all power from computer, hold down the power button for 30 seconds this for your safety and the safety of the components and to close the circuit
  • Remove the casing or remove the RAM panel if it is a laptop
  • Remove all the memory modules one by one. But, make sure while dealing with the internal parts you are grounded properly. Ground yourself by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  • Replace the casing or the RAM panel if it is a laptop and put the remaining memory module(s) in a safe, static free environment.
  • If the problem persists, repeat the steps from the beginning by moving the memory module to another slot.

Repeat this until all slots have been tested. If all slots fail, the memory module may be bad. Test with one of the remaining modules. Continue one module at a time in one slot at a time until you find a good module and good slot. Test remaining modules in the good slot, test good modules in other slots to find bad slots, etc.

Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. You may want to run both Memtest86+ and the Windows Memory Diagnostics Tool overnight since they take a long time to complete.

Upon completion of the above steps, you will find out the actual reason behind the frequent BSoD. If the RAM modules are found to be faulty or the slots then you need to replace it for better functioning of your PC.
