MBP crashing, suspected GPU
Hey
So i have a MBP late 2011, top of the line set up. Lately ive been having crashes what seem related to the GPU (Radeon HD 6770M) , or screen maybe.
I cant pin point so far when it happens but suddenly it the screen would turn grey with vertical lines, then go back to normal for a split second before getting all pixelated then it crashes. Sometimes when i try to turn it back on it will get stuck on the grey screen after the apple tone, but before the apple logo shows up. i would have to turn off and on sometimes need to repeat a few times before it goes on all the way. Ive ran the extended hardware test, no issues found. ive ran clamXav found no viruses, i ran verify disk in disk utility it did fine one issue but said it fixed it. I keep my computer ventilated, its off the table so the bottom is mostly in the air and i have a small external fan blowing at the back. Im suspecting maybe it just needs a deep internal cleaning, opening it up and cleaning out all the dust. Maybe the gpu fan is completely clogged with dust? If not could be the GPU is dieing i guess.
Please ask if any more information could be helpful.
Thanks!
