After booting up(pressing turn on key) , it takes 4 minutes or more to be loaded login page(windows 7)[previously was taken 1 minute], besides, during this time, I just see black page but cursor can move but there isn’t any login field .
After logging , as much as I could check such as CPU usage,Memory RAM,etc is working fine.
I’ve not tested hardware .
HDD is a normal type.
Windows OS is old .
Anti-Virus is running.
This has recently been happened and previously was working absolutely fine.
What can I do to tackle this problem ?
