Sorry if this information has already been posted elsewhere; I used the search function and was unable to find anything. I am thinking it may be time to defrag my gaming computer... I've had it for six to seven years now and, until recently, I was under the impression that defrags only needed to be completed once. It was done about 4 years ago to the best of my knowledge. I was only recently told by a friend that it can be done more than once.
I am running the Vista 64-bit edition with 4 gigs of RAM. There is about 20 gigs of space left on drive C, which the system is telling me is around 10%. Lately, some of my games (mainly train simulators) have been lagging a little. Having said that, I'm assuming a defrag might help.
I'm not quite sure how to go about it. To the best of my knowledge, I should free up whatever space possible, run checkdisk, and then run the disc defrag utility... but I'm not sure if it's that simple or if there might be more to it. Any input would be greatly appreciated. Thanks.
