The lines are random horizontal lines that mess up each of my windows. If I maximize/restore down the window they disappear temporarily. I have an HP dv5-1007ca, if that helps. I have also updated my graphics drivers to the most recent from the intel site. Has anyone seen this before? Thank you, M

Is this the only time you have these problems with your display? Were you offered a video driver update from Windows Update when you first installed and activated? Sorry for all the questions, but........ In order to troubleshoot your problem we need to know more detailed specs of your system hardware. 1. Go to Start > Run, and type msinfo32, look under the Components section for hardware identification 2. Go to Control Panel > Device Manager and look for any entry that has a yellow flag beside it 3. The manufacturer name and model number of your PC, if applicable 4 Please fill out your computers specs in the User Control Panel here on the site as well. It will then appear next to your name. look at my posting and you'll see the drop-down arrow. The exact make and model of your motherboard and video card would be of great help also. Are you using the 32-bit or 64-bit version? Was it a "clean" install or an upgrade? Are you dual-booting? Are you suing the official RC directly from Microsoft? Did this occur immediately after install? Do you recall installing any software that may have caused the problem? For More Information and know how to resolve windows 7 aero problem
