Problem: After installing Windows Vista on my laptop, my display is showing vertical colored lines in Red Green and Blue. There are three lines specifically that show. Two of them are symetrical (the same distance from the center and the third is nearly touching one of those two.

Will post more this afternoon when I have the laptop information available.

Thanks.

reported three narrow vertical RGB lines after installing Vista. That symptom can be either hardware (LCD panel, cable, or column-driver failure) or software (driver/refresh issues). correctly suggested drivers, but the fastest way to separate the two causes is to run a few simple diagnostics first.

First diagnostics: reboot and watch the vendor/BIOS screens before Windows loads — if the lines are present there, the problem is hardware. Attach an external monitor — if the external display is clean while the laptop screen shows lines, the failure is in the panel or its cable/connector. If both screens show the same lines, the GPU/logic board is likely at fault. Also try Safe Mode or low-resolution video (640x480) and a Linux Live USB; disappearance of the lines in those modes points to a driver/OS issue (so follow and update OEM/vendor video drivers).

Physical checks and safe handling: power down, remove AC and battery, ground yourself, then gently flex the screen at different angles while powering on — changes in the lines with lid movement usually indicate a loose/damaged LVDS cable or worn cable at the hinge. Reseating the panel connector at the motherboard and at the LCD (only if comfortable and with correct disassembly guides) can sometimes fix it. If the stripes appear even with a clean external image and are present before POST, the panel column-driver or GPU is failing — panel replacement or motherboard repair will be needed.

Practical next steps: back up data immediately, document when the lines appear (BIOS vs Windows), try the external-monitor and Safe Mode tests, and contact HP support if under warranty. For out-of-warranty units, get a shop quote for panel vs board repair before attempting risky fixes like reflow.

Have you installed the most recent video drivers from the HP site? If they dont work, try the current video drivers from the nvidia site.

What screen resolution, colour depth and refresh rate are you running at?

P.S there seems to be a hardware problem with HP laptops (but it seems to mainly be the Pavillion ZDxxxx range.
