Computer will not boot to normal and verticle lines on monitor, dell XPS410, windows vista 32 bit

SOURCE: Blank screen or vertical colored lines on monitor

sounds like a graphics card failing

is it on board graphics ?

if so try a graphics card in there see if that helps it

also if you could borrow a monitor and see if that helps

its either one or the other and is a process of elimination

SOURCE: Computer will not start past safe mode screen

In safe mode, hit start button -run, and type "msconfig" in the box , hit enter.
the system configuration utility opens.
select startup tab at the top
when the startup screen opens, UNcheck all the boxes, press APPLY, then OK
the computer will prompt you to restart, when it restarts it will give you a message saying you have use the system configuration utility to change the way windows starts, this is normal. Check the box that say dont show this again and click OK.
doing this will keep the programs set to start when windows starts from starting untill you start them manually. If one of them is causing the freeze, this will make the system accessible.
Keep in mind, you may want to turn some of them back on after you get the computer going and when you do , turn them on one at a time and restart the computer after each change. this way you can identify which program is causing the problem.
Hope this helps. please repost if you have more questions

SOURCE: Thin vertical lines on screen

You need a new LCD screen.
Thats a common problem with those panels
Or can be a hardware defect that occurs when the screen wasn't properly tested at the factroy

SOURCE: monitor screen with pink line

While I've never seen the stripe be pink, it's not impossible for it to appear that color. Your monitor is bad, and isn't easily or cheaply fixed.
