I have a problem with my computer's display. If I let the computer start up normally the display is fuzzy, full of horizontal lines and I am unable to make out anything on the screen. When I use safe mode the display is fine like nothing is wrong.

I'm running Vista Home Premium SP 2 on a dell studio 540. I'm using an hdtv as my monitor. It is attached to the hdmi port on my computer. I don't have another monitor that I can use.

     This is what I was doing immediately before the problem started. I was running a live boot of Kali-Linux 1.06 but the display was cut off I couldn't see the full desktop. I was unable to shut down the computer because I couldn't see the shut down menu. I pressed the power button on the front of the computer to turn it off. When I turned the computer back on the BIOS screen appeared as usual but then the screen went blank and stayed blank. So I tried rebooting the computer a few times and a few hours later the screen started showing the fuzzy horizontal lines that I see now.

I did a system restore to the day before I ran Kali- Linux but it didn't do anything.

I reset the bios settings to factory default because I read that it might help but it didn't make a difference.


Thanks in advance

If the problem doesn't reoccur in Safe Mode it would be your graphics driver.


When you boot into Safe Mode the graphics driver used isn't what you normally use, it is a driver which is native to the operating system.


I would suggest uninstalling the graphics driver, then download the driver from Dell Support.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
