Satellite M30: coloured lines run up and down on display

Hi there
Ive got a problem with the display on my Satelite M30. I can boot into windows fine etc but coloured lines run up and down my display as well as general artifacts. I cant even install nvidia drivers without a blue screen.
The strange thing is that if i apply pressure to the left side of my touch pad i can instal the drivers and everything is fine! Release the pressure and the computer crashes. Ive opened the laptop up and can find nothing that could be causing this.
Any insight here?

Hi
You could check if the problem is related to the LCD monitor or to the graphic card.
Try to connect the external monitor and check if the lines appear on the second display.
If the lines does not appear then the graphic card should be ok.
Did you try to install the graphic driver from the Nvidia website??? Such drivers are not designed for the usage on the Toshiba notebook. You have to use the own Toshiba graphic drivers because the drivers supports an overheating protection.
If the temperature increases to the higher, critical level the Toshiba drivers will decreases the graphic card performance.
The other graphic drivers dont support such function and therefore the graphic chip can overheat!
Anyway, I think also the technician should check the notebook

Have lines appearing on my screen and coloured barcodes running across top, what is the cause

Thin lines have appeared running down the length of my screen and colloured barcode type short lines running across the top of my screen. Has anyone suffered this before and knows what the cause is and maybe the remedy?

It could be a hardware problem - bad GPU. Best to take it into your local Apple Store and have them run diagnostics on it... what model MBP do you have (year & screen size)?

A Prepares c700 (c742au) with Vista. graphics just coloured lines, but ok in safe mode??

Hi
I have a presario c700, I have just formatted the hard drive installed vista, as before, computer starts up fine it then installs update sand drivers, i then lose the graphics all I get are multi coloured line on the screen. It works fine in safe mode.
Any help would be great.
Thanks

The video card has gone bad. The issue is video memory. The card only uses video memory above the minimum when Windows is loaded and the driver installed. So you can run in safe mode or even in Windows with default drivers but only when the actual video driver is loaded does the system try to access the higher video memory and it fails. The c700 has the same issues as the ill-fated dv6000 series. Your motherboard can be repaired. If you want more help post back as there are ebay vendors who will repair the motherboard/video card for around $70 and I can find the link for you given a little time.

Video bug - vertical coloured lines (Oly E-M5)

Gday all
Im having a strange bug with video playback in LR4 where the video plays with audio however there is vertical coloured lines through it. If I export it, it works fine, if I play it outside LR4 it works fine. Its just within LR4. Has anyone had this? Btw, the video playback works fine with my E-5. I noticed it in 4.3 of Lightroom but to be honest I didnt place too much emphasis on it at the time cause I was showing some video and ended up viewing it through explorer. The after updating to 4.4 it was still there.
Below is what it looks like. Im running Win 8 Pro with teh Media Centre pack, 16Gb ram with an i7. But as I said, it runs great outside of LR.

No one else has had this happen?

How can I turn off the 2 blue lines running vertically in my image in Photoshop?

How can I turn off the 2 blue lines running vertically through my image in Photoshop? I want to save my work but do not know if these lines will persist in the saved image.

I assume the Rulers are showing. In that case, to get rid of each line use the Move tool to straddle the line and drag it whence it came. I really didn't need to add this comment but it is the first time in years I have had a chance to use the word "whence".
Is this a guide I see before me? Doeth it conspire to confuseth mine eyes with sapphire lines that afoul my worthy parchment, and draw my quill from its righteous path? Be gone foul guide from whence thou cometh. Verily, forsooth, and hey nonny nonny.

MBP strange flickering blocks of multi-coloured lines on screen

Hi
over the past few weeks when awaking from sleep my MBP 13" (mid-2012) has had this problem <a href="http://s1204.photobucket.com/user/sjwhite26/media/IMG_0035.jpg.html" target="_blank"><img src="http://i1204.photobucket.com/albums/bb404/sjwhite26/IMG_0035.jpg" border="0" alt=" photo IMG_0035.jpg"/></a> i.e. blocks of multi coloured lines flickering on the screen.
You can use the machine, but its incredibly annoying and and reboot gets rid of it. My issue is that it is happening more and more. I also have the issue when the MBP won't always wake from sleep when using the mini display port attached to my screen. This is viewable on the laptop's native screen as well as the dell screen.
Any help would be appreciated. I've tried all the PRAM etc resets.
Thanks

I have a thin horizontal line running across my screen about 1/4 of the way from the bottom of the monitor. Why is it there and how do I get rid of it?

There is a thin horizontal line running across the width of my screen about 1/4 of the way from the bottom. This line, along with an occasional vertical line about a 1/3 of the way from the right side of my monitor, started appearing about 7 days ago. Usually the line would disappear after a restart but now it seems intent on staying. Does anyone know what is going on and how can I resolve this?

Why do I have a thin blue line running down the screen?

There is a thin blue line running vertically down my imac screen a little to the right of the centre. It disappeared for a while - i think after I tapped a certain key - but then re-appeared and will not go away. What is it? How do I get rid of it? Mark

Sounds like a problem with the display. Contact your local Apple Store or AASP and make an appointment to have the display looked at. > Apple - Support - iMac - Service FAQ

Does this only happen on specific pages?

Vertical black line running down imac screen

This morning i noticed for the first time (wasn't there yesterday) a thin black vertical line running down my 21' imac screen.
Any suggestions?

Take a screen shot & view that in Preview, move the Preview window around, if you see 2 black lines it a Video card/VRAM problem, if the line does not move moving the pic around then it's the LCD or cable.

My iPad has not been dropped or damaged at all. The screen is grey fuzzy and has coloured lines down the middle. iPad 3 also.

Basics from the manual are restart, reset, restore.
Try all of these.

I just upgraded my Firefox program and now a group of black lines running 10-15 deep are appearing on my monitor from time-to-time

I just upgraded my Firefox program to a new version and immediately I started seeing a group of black lines running 10-15 deep running across my computer screen while on the Web. As I scroll down they sometimes disappear. Then they reappear. It doesn't happen all the time. But often enough.

Contact Apple. That sounds like a hardware issue in the graphics circuit.

Try #2 and #3 in link below. If neither work, you most likely have a hardware issue.
