Hello,Batu Ozay
Welcome to Microsoft Community.
It sounds like you're experiencing significant performance issues with your newly installed Windows 10 on an older computer. Given the symptoms you've described, the lag could indeed be due to missing or outdated drivers, especially for your integrated graphics (Intel HD Graphics). Additionally, the system's overall performance could be affected by other factors, such as system specifications not fully meeting Windows 10's requirements or possibly some configuration settings.
Let's tackle this step by step:
1->Update Windows
Ensure that your Windows 10 is up to date. Windows 10 Updates often automatically detected and pushed through with updates, so I would recommend that you try checking all Windows 10 update lists first.
2-> Install/Update Drivers through
You mentioned that your processor is Intel, try visiting Intel's support assistant page. Download the corresponding driver. The following is the link to the official website. This assistant will generally automatically detect your hardware to install your CPU/GPU fan.

3-> Optimize Performance Settings
Adjusting Windows for best performance can also help:
- Press Windows+i > Go to Systems > Scroll down and Click About> Advanced system settings > Settings under Performance. -> Choose Adjust for best performance and apply the changes. This will disable many visual effects that can slow down your system.
- Remember to plug in your computer when performing these operations to ensure it is running as plugged in. Watch to see if your framerate improves.
By following these steps, you should be able to improve the performance of your Windows 10 installation. If the lag persists even after these adjustments, it might be worth considering if the computer's hardware is just too outdated for a satisfactory experience with Windows 10, in which case exploring lighter operating systems or ultimately upgrading the hardware might be necessary.
Feel free to let me know the status.
