I recently purchased a HP Envy dv7 laptop which was upgraded from Windows 8 to Windows 8.1 with 1tb hdd and 12gb ram. Actually, I purchased the laptop used. I updated some but not all the drivers and it functioned normally for about a week. Now, the laptop hangs at every click of the mouse even when the task manager says that only 1% of the cpu and only 1gb of its 12gb ram is in use. Also, once in a while, it shows nothing but a blue screen.
I carried out a hard disk test and the results were Hard disk smart check : failed Failure id: 64jf2m-69a7qh-qfpjxg-60ct03 Product id: d0x36ea#abu
