hoizontal lines

[nancyb47]

When starting windows7, horizontal lines cover the entire screen. I have to shut down the computer and restart to correct this, sometimes several times.

Hello Nancy and welcome to Seven Forums.

It would be very helpful if you could provide some information about your computer. At the top of any Forum page, click on "User CP". Then in the left column click on "Edit System Spec". Fill in as much information as you can, especially the manufacturer, model and whether it's a desktop or laptop.

From what you've described those horizontal lines could be a bad graphics card, a bad monitor/screen, a driver problem, etc. That's why it will help to know what kind of computer you have.

In the meantime, try starting your computer in Safe Mode by accessing the Advanced Boot Options menu.

See if those horizontal lines still appear. If they don't you could try rolling back your computer to an earlier date/time (prior to when this problem first appeared) by using a system restore point.

You could also go through these troubleshooting guides. They'll help isolate if this is a software problem or a hardware problem.
