The Common Mistakes and Solutions for Upgrading Your GPU and RAM


What could be causing my computer to perform poorly after upgrading my GPU and RAM?

I have recently upgraded my GPU from a GeForce 750 ti to an msi ventus 2x 3060, and my RAM from 16gb to 32gb. However, instead of improving, my computer has been experiencing various issues, such as mouse lag, audio and mic glitches, and app crashes. These issues persist even after I tried different troubleshooting methods, such as checking my drivers, running a UserBenchmark test, and reinstalling the old RAM. I suspect that the GPU might be the culprit, but I am not sure how or why. Is there anyone who can explain the possible causes and solutions for this problem?


Upgrading your GPU and RAM can be a great way to boost your computer’s performance and enjoy a smoother gaming experience. However, sometimes things can go wrong and you may end up with a computer that performs worse than before. This can be frustrating and confusing, especially if you have spent a lot of money and time on your upgrades.

There are many possible causes for your computer’s poor performance after upgrading your GPU and RAM. Some of the most common ones are:

  • Incompatible hardware: Your new GPU and RAM may not be compatible with your motherboard, CPU, power supply, or other components. This can cause instability, errors, and crashes. To check if your hardware is compatible, you can use online tools such as [PCPartPicker]( or [UserBenchmark]( You can also consult the manuals and specifications of your components to see if they meet the requirements.
  • Insufficient power: Your new GPU and RAM may require more power than your old ones, and your power supply may not be able to handle the increased load. This can result in low performance, shutdowns, and damage to your components. To check if your power supply is adequate, you can use online calculators such as [OuterVision]( or [Newegg]( You can also look at the wattage and efficiency ratings of your power supply and compare them to the power consumption of your components.
  • Faulty installation: Your new GPU and RAM may not be properly installed in your computer. This can cause loose connections, poor contact, and overheating. To check if your installation is correct, you can follow the instructions and videos from the manufacturers or reputable websites. You can also inspect your components and make sure they are securely fitted in their slots and connectors.
  • Outdated drivers: Your new GPU and RAM may require updated drivers to function properly. Drivers are software that allow your components to communicate with your operating system and applications. If your drivers are outdated, you may experience compatibility issues, glitches, and errors. To update your drivers, you can use the official websites of your components or software such as [Driver Booster]( or [Driver Easy](
  • Malware or viruses: Your computer may be infected by malware or viruses that are slowing down your system and interfering with your components. Malware and viruses can be acquired from unsafe websites, downloads, or attachments. They can also be hidden in legitimate software or files. To scan and remove malware or viruses, you can use antivirus software such as [Malwarebytes]( or [Norton](
  • If none of the above solutions work, you may have a defective or damaged GPU or RAM. In that case, you may need to contact the seller or manufacturer and request a replacement or a refund. You may also need to consult a professional technician or a computer expert for further assistance.


your GPU and RAM can be a rewarding and enjoyable process, but it can also come with some challenges and risks. By following the tips and suggestions in this article, you can hopefully solve your computer’s performance issues and enjoy your upgrades to the fullest.
