I've noticed my gaming laptop's performance has really declined lately. I bought a second-hand GE75 Raider in 2021, and it used to run demanding games like Red Dead 2 and Elden Ring smoothly. Now, I'm experiencing frustrating lag where my performance alternates between decent and terrible, especially in games like Borderlands 4 and Monster Hunter World. I've checked the system info and my laptop is equipped with an Nvidia GeForce RTX2080 Super, Intel Core i7-10750H, and 15.8 GB of RAM, but it struggles even when I have little running in the background. I freed up space by deleting unnecessary files, and my drives have ample free space. I cleaned out visible dust but couldn't get inside the fans due to tight screws, and the thermal paste seems dried out. Even using a cooling pad doesn't help; the issues occur whether the laptop is hot or not. I'm looking for advice on what might be causing this and any steps I can take to improve performance. Any help would be appreciated!

Start by monitoring your CPU and GPU temperatures while gaming. If they're overheating, that could be causing performance throttling. You can use tools like Libre Hardware Monitor to keep track. If temperatures are high, you might need to fully clean your laptop and replace the thermal paste, especially if it's old and dried out. Investing in a good quality screwdriver set is also key since laptop screws can be small and sensitive.
What temperatures should I be looking for? I checked my CPU and GPU while gaming and they went up to 93°C!

Are there specific screwdriver sets for laptops that you recommend, or is a regular set enough?
