Yes, all listed items are done on a regular basis. I have not run Dell diagnostics. Can I do that, or must I contact dell support for that?
Thanks for your interest.
Thanks! You know, after I sent you the last response, I thought "Oh yeah, my Dell resource CD!" Duh....!!
I ran that, and when I came to the section of it where my keyboard is examined, and a "keyboard" is displayed for you to click on each key..... Well, when I did the clicking, I received error messages, saying something was not as it should be. For ALL of the keys. So, I have ordered a new keyboard from Dell; be interested to see if that fixes the problem. Only about $20 for it, so worth the chance of getting another one to replace this I'm using. I have a feeling.....
I'll let you know. Everything else on my machine checked-out great, soooo.........
