Screen behaviors: crash, lines, colors, bars...

Question

Hello everybody!I&#x27;m having some issues with my MacBook Pro... Two weeks ago it started to crash and do crazy things on the screen... Check these pics, please...I started to search for some solutions, so I reset PRAM, I verified the Hard Disk several times and used the Installation Disk four or five times as the Disk Utility said there were a problem with modules or something...The thing is I backup all my info and I clean my Mac and reinstalled everything, twice... Now, the screen goes to white/gray and I do not know what else I can do...This is the report from EtreCheck...Any help?Hardware Information:    MacBook Pro (15-inch, Early 2011) (Verified)    MacBook Pro - model: MacBookPro8,2    1 2.2 GHz Intel Core i7 CPU: 4 cores    4 GB RAMVideo Information:    AMD Radeon HD 6750M - VRAM: 1024 MB    Intel HD Graphics 3000 - VRAM: 384 MB        Color LCD 1440 x 900System Software:    Mac OS X 10.6.8 (10K549) - Uptime: 0 days 0:22:14Disk Information:    TOSHIBA MK7559GSXF disk0 : (698,64 GB)        - (disk0s1) &lt;not mounted&gt;: 200 MB         Macintosh HD (disk0s2) / [Startup]: 698,32 GB (669,44 GB free)    OPTIARC DVD RW AD-5970H  USB Information:    Apple Inc.

If you have a monitor you can connect the MBP to it.  If the monitor displays the same image as the MBP, then the GPU is faulty.  If the monitor is displays a &#x27;normal&#x27; image, then the display or the display connection is faulty.The best option is to make an appointment at an Apple store genius bar for a FREE evaluation.  You then will know the exact reasons for the display problems.Ciao.
