I had issues with both my laptop and desktop computers. They were running very slow and took forever to boot up. I called On Site Computer Services after reading about them on TOTV. Jason came to my house and tuned up both computers and down loaded some updates and now they're running smooth. He diagnosed the issues right away and got them addressed. His fee was very reasonable. He came at the appointed time,even a little earlier. I would recommend him to anyone. 352/638-1865
