Postup řešení
- 1 Increase the page file size. Press Windows key + R, type 'sysdm.cpl' and press Enter. Go to the Advanced tab, under Performance click Settings. Go to the Advanced tab, under Virtual memory click Change. Uncheck 'Automatically manage paging file size for all drives', select your system drive, choose 'Custom size', and set Initial size and Maximum size to a value like 4096 MB (or 1.5 times your RAM). Click Set, then OK. Restart.
- 2 Close unnecessary programs to free up memory. Press Ctrl+Shift+Esc to open Task Manager, go to the Processes tab, and end any high-memory processes you don't need.
- 3 Run SFC and DISM as before to repair system files.
- 4 Check for driver updates, especially for storage and graphics drivers, as they can affect memory management.
- 5 If you have a small amount of RAM (e.g., 4 GB), consider adding more RAM or reducing the number of programs running simultaneously.
