Computer boots up with many pixel problems

If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.

the actuall screen LCD is bad.
in most cases.
supper common failure.. 2008 PC.
see page 31 , part 5 here. bingo, change that out.
there are 2 types used, only your full PC part number on
the service tag show this, post that and we go to the HP parts surfer and look it up.

Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

The blue screen that you see is what they call "the blue screen of death". The error that you have is Unmountable Boot Volume. This is caused by the operating system not being to load due to hard drive errors. This happens due to the computer being shutdown improperly or hard drive problem. I suggest that you contact the manufacturer of the computer so they can try and restore the computer without formatting or changing the hard drive.

The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Please rate this if it this helps.

Blue thin lines before it boots will rule out an operating system or driver fault. So it would appear something in the machine has failed.
Do you have a VGA monitor you can connect to it and see whether it shows the fault? This will show that if the fault also shows on the external monitor, it is likely an electronic fault on the main board, whereas if it works on the external monitor but not on the built-in monitor, my guess would be the cable that goes from the main board up through the hinge of the screen into it, or a connector, or an actual fault with the LCD display.
Windows booting normally once the display drivers were disabled indicates to me that Windows is no longer detecting the faulty display and therefore boots normally - possibly pointing to failed electronics in some way. It could even be corrupt BIOS that controls the video or something along these lines, though that's unlikely.
Good luck, either way it sounds like it's off to a computer repair shop. Is it under warranty?

go n format it by using a recovery drive...there may be a start up errors occured in windows

Sometimes they make the recovery disk with windows on it, but not the programs that start windows during the boot up phase. One of the three main files that boots into windows is corrputed or your Master Boot Record is missing. There are two options you can try without the OS disc so lets see if one of those will work: 1) boot up and press F8 to enter safe mode. Once in safe mode sometimes you can also get into window because just the minimum of the program is loaded. F8 Safe Mode>in windows>click start>accesories>system tools>system restore. It will allow you to restore your computer to a prior date before you have problems. 2)if that don;'t work then F8 safe mode and while in safe mode choose Last Known Configuration. Kinda works the same way as restoe but you don't have to be in windows to do it. If those don't work then get your hands on a windows xp disc, anyone's will do, don't have to be yours. Let me know how it goes.
Rate this solution. You can also find out about this at support.microsoft.com>help and support>type in Windows XP boot disk in the search engine.If those don't work let me know and we'll move on to phase II.

The vertical line is a bad pixel sensor at the edge of the screen, your screen has hundreds of vertical and horizonal pixel sensors. This is an indicator that the screen is going out and need replacing.
