Hi @gs pratap
Windows 10 sleepiness is a common concern these days and as have clean installed the PC a simple registry tweak might sort this out. But make sure you are backing up the registry or creating a restore point before this.
- Open Regedit as admin
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
-Double click on Attributes
-Enter number 2. - Go to advanced power settings (click on Windows button, write power options, click on Power Options, in the selected plan click on the Change plan settings, click on the Change advanced power settings).
-Click on the Change settings that are currently unavailable
-Click Sleep, then System unattended sleep timeout, then change these settings from 2 Minutes to 20 for example.
-Restart and check if the issue occurs again.
Hope this resolves your Query!!
