I am having an issue with my Dell Inspiron N 5010. The OS I am using is Windows 7.
The screen on my laptop has started to almost mirror itself every few seconds on the bottom half of the screen. I say almost because the bottom half of the screen is still visible beneath the sort of ghost like top half. The color on the entire screen gets lighter and has a stronger magenta hue to it. I have not recieved any error messages or heard any beeps when it starts up. The flashing/mirroring starts from the moment I power up. Every few seconds when it isn't flashing/mirroring, the screen is perfect. No color hues, no lines, no mirroring or flashing.
Troubleshooting I have done
I have tried opening and closing the screen all the way and the issue is not effected. I have gently twisted the screen by pushing slightly on each top corner while open as well as pushing all across the bottom and this also has no effect. I removed the battery and disassembled to the point where I could remove the screen connection from the motherboard and reconnect. No effect. I updated my Norton virus software and ran this to see if maybe a virus was the cause and none was found. I also uninstalled the video driver and reinstalled the latest version. I checked the refresh rate and it was still 60hz as it doesn't give me any other option. I went to the Dell website and updated the BIOS as well.
I am left with considering the video card? I have seen videos where people have heated the video card up to melt the solder to "reflow" (not sure if that is the right term) the connection. I am fairly mechanically inclined but using heat directly on the motherboard stil scares me a little. I'm not under warranty any longer so any troubleshooting advice would be wonderful. I really hate just ordering random parts if it could be something simple.
Thank you for your time!
