Defragment your hard drive and increase your paging file. Your hard drive is either too full and needs you to delete as much unnecessarily large files like movies and empty recycle bin. Or your system is low on ram as a result of too many background programs running at startup.

make sure u have at least 15% free hdd space , your laptop might need servicing like cleaning the heat sink vent ,fan and checking to see if the cooling paste has dried up.

If you're in lag i can help u do that.
