Windows 7: Getting weird vertical black bars in window

I'm not sure if this is a RAM, or video card issue. I've just started seeing this today. Seen it happen in an active and inactive application window like FF. Poppeeper. When I move the bar of the app around (disappearing below the start menu bar) then bring it up again, the problem is gone.

Any ideas which hardware/software is starting to fail?

Oooooh. This looks like either a driver issue or a bad display card. Is this a laptop or a desktop? If it's an HP laptop, does it have the ATI or the nVidia display chipset? My wife has a recent HP Laptop with the ATI display system and it had been notoriously hard to get working correctly. If you can post that information I'll see what I can do.

Andacar.

I'd upgrade display driver, if latest uninstall and reboot to reinstall it.

If that doesn't help reinstall the video card checking for debris in slot and connection is tight.

Next run a full scan with Malwarebytes.

Then SFC -SCANNOW Command.

Establish a Clean Boot to make sure another program is not interfering, check the logs and System Resources and work through the other steps in Troubleshooting Steps for Windows 7

Thanks. This is from the desktop (in my signature-system specs). Will see if a new driver fixes this.
