My Dell Optiplex 3010 powers up but when i wait for it to show the windows log in the screen only displays purple lines running across the screen. I have tried rebooting in safe mode and changing the vga cable but it doesnt work. Im assuming this has something to do with my video card? Any advice would be appreciated.
Hello! Which 3010 do you have? There are the small, medium, and large form factor versions. Does your computer come with a graphics card or are you connecting to the built in graphics? If its a graphics card, you could try opening up the system, taking the card out and putting in back in. Have you also tried using a different monitor?
