I have upgraded my pc from amd to i5 and ecs motherboard, it already got 2 gb RAM, 500 GB hdd
after getting i5 I thought I must install Windows 7... but after installing this OS im getting shocked by its speed, if i run a video on youtube then im hardly able to fill a pdf form while listening it... I have paid version of quickheal too..

Kindly help
