I am using DELL Inspiron laptop,OS is Windows 7.It was working well.But now few days its performance is very low.Very often I get a warning "Your performance is low", and it shows a message ,"Do you want to change the color scheme to improve performance.
Two options are shown:
1.Existing color scheme
2.Windows basic 7.0 color scheme
If I click the second option " Windows basic 7.0 color scheme",perfromance is improved.
Sometimes when I switch on my laptop,I could hear a small sound.
Please help me ...
