MahbubAlamRony, From Dell-Rahul: I'd advise you to keep the system up to date regularly and this will ensure to prevent most of the issues that you may see with the system.The best way is to use the Dell SupportAssist application as it will scan both the hardware and the system drivers. Open SupportAssist > Click on run all to check the hardware, any pending driver updates. If you see any driver updates pending, get it installed and restart the system when prompted. I hope this helps you best.Also, let me know if you need any further assistance and I will be happy to take it forward.
