|Hello, DAVEINCAPS, thank you for your reply. That makes a lot of sense. I shall pass that info along to my son.|
My son is about 20& a1/2, but knows a lot about his computer(and a lot of other things besides that), and so I give him a whole lotta credit! For example, His Dell was making a loud noise one day. He works, so he couldn't do anything until he came home. But, when he checked it out, he knew pretty much off the bat that it was because of a bad power supply.
Anyways, it isn't vibrating now, and hasn't been for several hours, but he did order a new fan.
Thanks so much for your help! Take care & God Bless!
