Any ideas why? and if i would change it does it gonna help me or not ?
The 2011 MBP is known to have GPU problems, which is likely what you are seeing here. However, a 2012 board can be installed in lieu of scrapping the machine, providing you can get a good deal on one that’s nearly identical spec wise or a major bump (Ex: i5->i7). However, it may not boot without reinstalling the OS if you upgrade it too far, so bear that in mind. That said, MacOS is pretty forgiving about it unlike Windows.You may also need to update the OS to get the current EFI updates, so I would try and save it for one or two final boots to make a backup (if possible, you may be able to bake the MLB to get the data off but this IS NOT REPAIR - it is a RECOVERY TECHNIQUE when all else fails). If you change the computer out, make sure you replace the HD cable while you’re in there - ESPECIALLY if you buy a 2012 15” to replace it. It doesn’t add much cost and it puts the all too common cable issue to bed when you will eventually want to replace the original drive with an SSD. More then likely, it’s going to be easier to get a 2012 machine and migrate the hard drive. Just be prepared to pay since these are prized machines unlike the 13” which comes and goes like it’s a dime a dozen - the HR AG machines are even more prized then the common base glossy ones so if you want that screen, you’re paying a good $1-200 more for it.
