Gray Band on LCD Screen

Dear Friends, hope all is well...

I noticed this light grey band on my screen. It was about 2-3 inches wide running from top to bottom or vice versa. I took some screenshot's of the window ( see attachments)

Have any idea what it might be? The computer from what little I've used it "appears" to be work properly?

The things that have obviously changed are a new hard drive, upgraded to Windows 7 Professional from Vista and I switched from Avira Free to Avast Free. The hard drive and OS upgrade were done by professionals not me...

Not sure if it's related but this morning there was an AVAST upgrade available when I first booted the computer. That is the first time I've seen the line again in about a week. It does go away sometimes in a minute or it may take about 10 minutes.

I ran the Dell System Detect app and it passed OK.

Is this another DELL snafu?

Is there anything I can do on my end to get rid of this or minimize it???

Thank You in advance for your care, cooperation and attention to this matter.


Sincerely, Ralph
