Feb 7, 2013 11:36 AM in response to norumalby leroydouglas,Apple hardware test form recovery boot, hold command R on reboot
or
New MacBooks can access HardWareTest by rebooting holding the D key, no disk required.

The key combination varies between systems, but should be one of the following on your Mac:
- Option + D (Early 2011 and newer; Mountain Lion tested)
- Command + D
- D

Feb 7, 2013 11:51 AM in response to norumalby ds store,Could be, likely because the dust hasn't been cleaned out of the machine and the vents are clogged causing the overheating.
Take it into a Apple Store and have them run a check, unfortuntly I don't think they will open it up there to clean the fans.

Feb 7, 2013 12:02 PM in response to norumalby MartinR,Quick way to tell if the problem is with the gpu (graphics card) or the display panel itself - connect an external display to your MBP.
If the problem also occurs on the external display, the gpu is probably at fault.
If the external display is fine but your MBP display gets fuzzy, the MBPdisplay panel is probably at fault.
How old is your MBP (what model), and is it still under warranty or AppleCare?

May 18, 2016 9:20 AM in response to norumalby 1tio1,I think my graphics card is failing but I'm not 100% sure.
I'm using a MacBook Pro 15" late 2011 running 10.10.5 and in all of a sudden my screen is acting weird. Blue and red line in overlay.
After a while I could use my MBP again, but yesterday it stopped working completely.
Since then I tried to reboot but every time it cuts of the boot and the screen goes completely blank.
I used the Apple Hardware Test to identify what might be the problem but with the normal as the advanced test results say there no issue with the hardware.
I recently started using an external monitor directly through the mDP. It's a fairly heavy screen running at full resolution of 2560x1440 but that's completely supported by Apple. The issues mentioned above started when I was using the monitor, but I had the same issues when I disconnected any external devices or peripherals later on.
So what could it be? Is it software or hardware based?
Someone that could help me?
