MBP has grey screen of death but tests say all hardware working

Question

I have a late 2011 15" MBP running 10.6.8. I was using is as I usually do when the screen went berserk and the sound froze up. After a restart I got an error messgae. Then It crashed again....I got it to restart again with the below error report. I managed to get most of it backed up, after starting it in single user mode, but then the screen went grey again and I clsoe the lid and got the three beeps. I also had a pink and blue --!--striped screen for a while. I tried resetting the PRAM. I also ran network utility and it said everything was okay. I have run the hardware test TWICE and it says everything is okay. Is this a video card thing? Or maybe the RAM is not working?Any ideas appreciated.Interval Since Last Panic Report:  14148256 secPanics Since Last Report:          2Anonymous UUID:                    5DA64AEF-EAD1-4850-95AE-7EF2AF32C29ETue Jan  7 01:03:16 2014panic(cpu 6 caller 0xffffff80002251fb): "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts, unresponsive CPU bitmap: 0x5, NMIPI acks: orig: 0x0, now: 0x0"@/SourceCache/xnu/xnu-1504.15.3/osfmk/x86_64/pmap.c:2741Backtrace (CPU 6), Frame : Return Address0xffffff81539ab760 : 0xffffff8000204d15 0xffffff81539ab860 : 0xffffff80002251fb 0xffffff81539ab8d0 : 0xffffff8000227ec9 0xffffff81539ab9c0 : 0xffffff8000228a52 0xffffff81539aba10 : 0xffffff80002184c5 0xffffff81539abb10 : 0xffffff80002188b3 0xffffff81539abb40 : 0xffffff8000215883 0xffffff81539abb70 : 0xffffff8000504b62 0xffffff81539abbb0 : 0xffffff80005045ae 0xffffff81539abbe0 : 0xffffff8000504564 0xffffff81539abc00 : 0xffffff8000502fb0 0xffffff81539abc50 : 0xffffff80004f77a5 0xffffff81539abc90 : 0xffffff80004f5585 0xffffff81539abcc0 : 0xffffff80004f77a5 0xffffff81539abd00 : 0xffffff8000524d17 0xffffff81539abd30 : 0xffffff8000526d83 0xffffff81539abd40 : 0xffffff8000555df2 0xffffff81539abd90 : 0xffffff80002bf1ca 0xffffff81539abdc0 : 0xffffff8000205536 0xffffff81539abdf0 : 0xffffff80002029eb 0xffffff81539abe60 : 0xffffff8000274176 0xffffff81539abed0 : 0xffffff80002c2daa 0xffffff81539abfa0 : 0xffffff80002e4536 BSD process name corresponding to current thread: Google DriveMac OS version:10K549Kernel version:Darwin Kernel Version 10.8.0: Tue Jun  7 16:32:41 PDT 2011; root:xnu-1504.15.3~1/RELEASE_X86_64System model name: MacBookPro8,2 (Mac-94245A3940C91C80)System uptime in nanoseconds: 1859851423447unloaded kexts:com.apple.driver.AppleUSBUHCI          4.2.5 (addr 0xffffff7f8133c000, size 0x65536) -

I had the exact same thing as you described above happen about 4 months ago.When I get home, I will look up the steps to fixed it.But essentially what I did was Restart the computer and open it in Diagnostic mode.Open the Disk Utility.Run the Repair option.Once I did this, everthing has worked without any trouble for 4 months.If you are not sure how to do this, I will add these steps when I post again later.

Hello friends! Last week I went to the apple store in my town and they confirmed that the motherboard is broken.Today I called Appl etechnical service and have opened an investigation because the product hasn&#x27;t got warranty.If everybody calls Apple, maybe they change the motherboard for free.

&gt; three beepsThree beeps indicates bad RAM.  Consider taking it in for a free diagnosis and estimate of repairs.Using Apple Hardware Testhttp://support.apple.com/kb/ht1509Power-On Self-Test Beep Definitionhttp://support.apple.com/kb/TA43884If it is bad RAM then it is user replaceable and you may as well upgrade it to 8 GB of RAM.See OWC (macsales.com) or Crucial to purchase the correct RAM.
