16. Keep the PC in Well Ventilated Area
It’s important to keep your PC in a well-ventilated area to ensure proper air circulation and prevent overheating. If you use your PC in an air-conditioned room, you don’t need to worry much about overheating.
To avoid overheating, it’s advisable to power off your computer once a day after completing your work or gaming. This will allow the computer to rest if it’s been in use for an extended period of time or if the weather is hot.
Avoid placing your computer near windows, open areas, or direct sunlight as it will increase the temperature. You should also use a high-quality thermal paste on your CPU to maximize cooling.
If you’re using a gaming rig or heavy programs that cause overheating issues, it’s best to invest in water cooling which is more expensive but worth the cost.
17. Reset BIOS Settings to Default
Resetting the BIOS settings to the optimized default one is a recommended method to fix COD Modern Warfare 3 stuttering, lags or freezing issues. However, it’s important to proceed with caution and follow the user manual guide specific to your laptop model or desktop configuration. Take note of the boot drive settings or information before proceeding. If your TPM is disabled, turn it on. Some laptop brands, such as Lenovo, push BIOS updates periodically via their own update software or support application. After updating the BIOS to the latest version, check if the issue has been resolved.
18. Try Upgrading Physical RAM
It’s quite unfortunate that the above methods didn’t work for you and your physical RAM isn’t sufficient enough to run video games properly. In that scenario, make sure to upgrade the physical RAM to double if your PC support RAM expansion. As most laptops or desktops do support up to 8GB/16GB of RAM expansion, you should upgrade it. Make sure to buy the same generation of compatible RAM stick to avoid the hassle.
Obviously, it may take some extra money from your pocket but this one-time upgrade of RAM will last many years without any issue. However, there is a catch. If your PC has only one channel for RAM then you’ll need to replace your older RAM stick with a new one. But if your PC has dual-channel for RAM then you can use both new and old ones like 4+4 or 8+8 depending on how much RAM storage you want to use.
