Guys I've Dell Precision M4800 which have 8GB ram, 1Tb hard disk, and 4GB Nvidia Quadro Graphics card.
But still, my laptop is running very slow. Even open a new tab on chrome is very hard for my laptop.
Please suggest me something to boost up its speed.
Thanks in Advance
If you don't have a solid state drive, buy one of those and install a clean setup of Windows on it. If you don't want to buy a new drive, at least do a clean setup of Windows, and run a test to make sure your drive is in good health. The laptop should have something in the BIOS to run a disk test.
