My minecraft is lagging on a gtx 770 graphics card?

My specs are i7 4770k, gtx 770 and 16 gb ram. I tried malwarebytes, adware cleaner and hitman pro and my drivers are up to date. All my games are lagging when loading things every 5 seconds. Please someone help.

Load time is dependent on harddrive. Might be time for a new harddrive.

I switched to Linux and this problem went away. Now minecraft runs faster than it ever did with Windows.

It sounds like your hard drive keeps trying to go to sleep, test to confirm with an ubuntu boot cd.
