PC very sluggish after installing new drive

  Eric Tan 03:05 16 Feb 10

My PC response becomes very sluggish after I upgrade my 250GB drive to a 1-terabyte drive with 64MB buffer. I was expecting the PC response to be faster with the faster 1-terabyte drive and 64MB buffer. There is a definite lag in response when I open any windows program.

Nothing has changes in my PC configuration except the drive.

Please advice what is the probable cause and how I can rectify this problem.

Are there any good PC activity monitoring software I can use/buy to track this slow response problem.

Not knowing a lot about it maybe you need a bigger power supply but that is only a guess.
