@ssaurabh2008 hey what about this? did you try it?
what so slow? everything?
I did check disabling the Kaspersky.
There was no difference in the performance, so I enabled it again after couple of restarts.
But today, the laptop performance (program launches, file copy, explorer) has improved considerably.
Looks like increasing the virtual memory has done the trick.
I believe everything. OP's new computer have 4GB RAM and 7200 rpm hdd. Windows 10 OS consume more or near 2GB RAM so that left OP not enough to run browser and basic applications. When OP's computer run out of RAM, Windows will switch to OP's 7200rpm HDD for virtual ram or pagefile and that is when OP going to experience a major slow down. In addition, OP's new computer has a 9 years old processor Phenom 2 x4 840 compare to OP's old computer with i5 8250u that will destroy the 9 years AMD processor.
There is some confusion.
My old desktop pc has AMD 840 processor, 4gb RAM and 7200 rpm HDD running on
Windows 7
My new laptop has i5 processor, 8GB RAM and 5200 rpm HDD, running on
Windows 10
Anyway, as I said in my previous reply, the performance has improved considerably now, after increasing the virtual memory.
I will keep you guys posted.
Thanks again for all the help.
