[QUOTE="Randy B. Singer, post: 1611084, member: 190607"] This is a known problem with certain Macbook Pros. I've heard from a bunch of folks reporting similar symptoms. Sorry to have to tell you that it's likely a bad AMD video card that Apple won't take responsibility for: [url=http://www.mactrast.com/2013/10/owners-early-2011-macbook-pro/]Owners of Early 2011 MacBook Pro Reporting Sporadic GPU Failures | MacTrast[/url] There is a free utility: gfxCardStatus (free) [url]https://gfx.io/[/url] that lets you manually set whether the integrated graphics or the discreet graphics are used. If you find the problem exists when using the discreet graphics, and not when using the integrated graphics, you have found the culprit. In any case, you should take your Mac to an Apple Store and have them have a look at it. They can diagnose a problem with the video card in seconds. Unfortunately it will cost upwards of $500 to fix this problem if it is the video card. [/QUOTE]
Verification
How many occurrences of a n-u-m-b-e-r between "d" and "f" in this example...(sdgs6ngklu3gd#f9%)?
