TX WLAN/GPU Nvidia Issue

My laptop ran into the dreaded nvidia heat issues, and I applied the penny fix and she's now running again.
However, when I first booted up after the fix, my Broadcom WLAN NIC worked fine, but the next day, it was gone again. I'm left wondering, since the card obviously was't burnt up b y the NVidia chip (since it worked for awhile), why the WLAN always suffer before the entire PC dies in all these NVidia chip cases? It seems rather odd. My only guess is that the NVidia chip also serves as the Northbridge in addition to the GPU, and thus when all the soldering starts to go, it's unable to accomodate the WLAN anymore. I ask since since I didn't heat up the underside of the board like most tutorials advise, so I think the soldering is still poor in my case. (in which case I;d have to do this fix again!) :\

The WLAN going out is usually a symptopm of the GPU issue. Most likely there is nothing wrong with your WLAN card and the fix just was not done properly. This happended to me the first time I applyed the fix also but It the reoccurance was not as fast as 1 day, I would recommend that you use the copper shim rather than the penny and if you don't have the tools or professional know how to do it on your own to take it to someone who works on motherboards. The cost for this repair is usually under $100 (/i would not pay more). There are also eBayers that provide the service and you can mail your board in if there is not anyone local to you who can do it for you. Make sure you check the feedback and go with someone reputable. I hope this helps

GT70 0ND492 WLAN or Sbar issues

I have been having an issue with fn+f8 and radio buttons used to turn wifi on/off. Currently my wireless card is on and connecting, but it can't be turned off.
It also seems like the bluetooth refuses to be turned off as well. I have tried installing .NET 4.5, uninstalling and re-installing Sbar and the problem persists.
So far support has suggested that I return it for replacement, but if there is a solution for this problem I would rather fix it and not have to go through the hassle
of shipping this one back and then waiting on another one. I have been reading through other forum posts, but it seems most of those have to do with WLAN connection
issues or a card that will not turn on. My apologies if I've overlooked a topic that already exists on this issue.
Here are the relevant laptop specs that I can think of:
GT70-OND492
OS: Windows 7 Ultimate
Processor: i7 3740
GPU: nVidia 675mx
WiFi card: Killer 1202
BIOS: E1762IMS.50T
EC Version: 1762EMS1 Ver5.03
Thanks

Just an update here. I am now a very happy camper! The issue has been resolved successfully, the radio buttons as well as fn+f8 works as intended now.
For others who may be having or may have the same issue I will list what steps were taken to correct the problem.
First: installed .NET 4.5
Second: uninstalled and then re-installed Sbar
Third: Attempted to reset EC
Fourth: Flashed EC for Windows 7 w/ backlit keyboard
It seems that when the vendor installed Windows 7 the EC for Windows 8 remained. I cannot say for sure that the first through third steps did not also
play a part in the issue being resolved, but I believe it makes more sense that the wrong EC was the culprit all along.
Anyway thank you very much for the replies (speedy ones at that)
Hopefully anyone else that has this same issue will find this post helpful.

MSI GT70 2PC-1044US - HDMI / GPU / FAN issues

MSI GT70 2PC-1044US - HDMI / GPU / FAN issues
I am having trouble with my HDMI port on a brand new MSI GT70 2PC-1044US . Whenever I plug my HDMI cable from my notebook to the TV, after a few minutes (5 - 20 minutes), my fan will start reving at around 5k RPMs and sounds like a jet engine. When this happens, according to MSI Dragon Gaming Center tool/monitor, the GPU temp reading hits 255 degrees Celsius, which is clearly a glitch. I used another monitor, msi afterburner, and when this HDMI problem happens, this tool reads a normal 40 degrees Celsius.
Here are the things I have tried so far but the problem keeps reoccurring:
1. Called MSI tech support, sent me the link to the newest BIOS and updated it
2. Called MSI tech support again, claimed the HDMI is controlled by the intel graphic controller, and they recommended that i update intel drivers (every software tool on my notebook says it's the NVIDIA GPU that controls the HDMI port /shrug???), so i did this as well.
3. Called MSI teck support again, they suggested I send the notebook back to MSI so they could take a look at the hardware. I did not do this because I did not trust the tech guy and did not want to wait a few weeks to get my notebook back
4. Luckily, the store I bought my notebook at was nice enough to replace my notebook for a new one. I got home, tested it, and the same thing happened. So I think we eliminated faulty hardware.
So now what? What else can I try?

have you done EC reset? https://forum-en.msi.com/faq/article/how-to-reset-the-ec-embedded-controller
can you try to plug the HDMI into your dell screen[insteal of sharp TV] to check if the same issue will hapends?
Install latest Intel GPU drivers from: http://www.intel.com/p/en_US/support/detect/graphics
then retest
-Yes, I did the full EC reset. Once the EC flash was done, I removed the power cord from the back and the battery and let it sit for a few minutes before restarting.
- My Dell monitor is old, and does not have an HDMI port, but I will try a different cable on a different TV.
-I already have the most recent intel graphic controller drivers, this one of the things the MSI tech support guys asked me to do by phone

Nvidia Issue or just broken? - Macbook Pro 17 inch 2008.

My screen intermittently started going into this very weird textured looking dark pale blue colour... sometimes with some lines sometimes with just the texture. For a time it would just start working by itself. I've been quite hard on the computer travelling extensively on bumpy rides, so I wouldn't be surprised if something is just loose.
The reason I want to try and figure it out first is that the first place I took it to said it was water damage, kind of funny. They said I needed to replace the screen, I said no just give it back... and then when I fetched it the screen was working again!... they apparently stepped on it by mistake - Im not kidding! The whole body is slightly bent. It worked for about a year now, but stopped again last month.There is a photo of how it looks here:
http://nic.co.za/images/laptop_screen.jpg
I bought a 27inch imac to work on but desperately need my older machine to be mobile as well.
I've tried to find the exactly the same issue online but they all seem slightly different. I bought my laptop in Los Angeles but am currently in South Africa.

Hi m, and welcome to Apple Discussions.
Sounds like it could be a connection, a cable, or the GPU. Read about the NVIDIA issue, but given water damage and physical damage, I strongly doubt the machine will qualify for the free repair. Still, it wouldn't hurt to have it tested and see.
I'm sure it's too late now, but if a repair shop stepped on my MBP, they'd be repair the damage or compensating me for it . . . .

New version of photoshop CC 2014 freezes on my Macbook pro late 2013. GPU related issue?

Since upgrading to newest version through Creative Cloud, Photoshop Freezes at start up:
- when launched from LR5 ("modify photo in CC2014"), photoshop launches, photo is displayed, then I get a message that "an incompatibility with the graphics components was detected and that photoshop temporarily deactivated graphics components" (in french). Then freeze. Impossible to access photoshop/preferences to see the open gl settings as shown in th faqs
- when launched directly, it opens and then freezes a few seconds afterwards
Tried to uninstall and reinstall through CC, unsuccessfully.
Anybody seeing same behavior?
Macbook pro retina 15", late 2013, Iris Pro GPU + Nvidia GT 70M GPU, running 10.9.5, all Apple updates done.
Thanks

Nobody who has the same problem or who can help me?

Extended warranty valid for secondhand mbp without receipt? (nvidia issue)

I have a black screen and proably the NVIDIA issue (as described in article TS2377 on the apple site). I am going to local apple stores tomorrow to get some tests done. However I have traded the mbp3.1 with an iMac last year and I dont have a receipt. Would this be a problem to get a new NVIDIA and logicboard free of charge?

Hi. I dont know the original owner. we traded through a secondhanded apple site. he came over. we swopped but i have no further information.
the macbook pro is from june 2007, but it has the NVIDIA issue which should be fixed free of charge, as described here: http://support.apple.com/kb/ts2377
The mbp is a little over 3 years old, but this should not be a problem as apple says in the article ^^
+If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within four years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.+

Display dead, then comes back to life- can Nvidia issue be intermittent?

I have a MacBook Pro MA896LL (Core 2 Duo Santa Rosa) that I use with an external display most of the time.
Rebooted a few days ago only to see nothing- sleep light on the computer was solid but laptop and external displays were blank. Disconnected external display and power-cycled, same thing- discovered that the computer is actually on but just no video (can boot in firewire mode, etc.). Tried the usually stuff, reset PRAM, SMC, left it off for a while, nothing. Figured I must have the dead Nvidia card issue.
Anyway, booted it back up today in Firewire mode to finish backing it up, and lo and behold, the display is working again!
Question- can the Nvidia issue be intermittent, or is it just working or not?
I have AppleCare, but repairs unfortunately involve me flying to Miami and hanging around for a few days while they repair it, and I'd hate to go and then they tell me it is not that problem, only to return home and have it again.
thanx

Welcome to Apple Discussions!
I think that the NVIDIA problem can be intermittent, and the fact that the external display was also blank does indicate the graphics card.
While the display is working, you might try running the extended version of the Apple Hardware Test and see if you get anything in the way of an error code.
Also, call Apple on the telephone to report the problem and to get a case number. Explain that the problem seems to be intermittent, and for that reason you would prefer not to fly to Miami for the reasons you gave. Ask if there is an AASP in your area that could do a diagnostic test. Apple has some sort of special procedure for testing for the NVIDIA issue, and it may be that someone local can do this for you.
If you get any results on the AHT or any other diagnostic test that would confirm the problem, then you can arrange to have the repair done at your convenience.
In the meantime, you might keep a log of when the problem occurs. For example, the chip may work fine when the computer has been off a while and is cold, but the problem might occur when the computer has been on a while, and maybe with intensive processor activity. If you can discover any conditions which will reliably cause the problem to occur, you will be much more successful at showing it to someone at Apple.
Good luck!

NVIDIA issue?

Having been using my first Mac for quite a while now. It did its duty pretty well. Then I was just curious to know how fast it is in 3D games. Unfortunately, I know how slow it is now! I only tried Second Life so far. I didn't feel anything before I tested the same game on my old IBM R51, which has 1.5GHz, 512M memory, ATI Radeon 9000, 40G 5400rpm HD. Here is the comparison on fps:
12"PB
standing still: 10-15
moving: 5-8
turning: freeze (for about 5 seconds)-5
best (no 3D structure in view): 25-30
IBM R51
minimum: 15
in most cases: 25-30
best (the same site with no 3D structure): 50-70+
The difference is huge. I feel pretty bad about this. Are you kidding me? Everything is better on my PB. Even if GeForce FX Go5200 is not as good as ATI Radeon 9550. I really didn't expect it to be worse than Radeon 9000. Although I am not going to play any "big" game on it, I am hoping it would handle some professional programs, such as Photoshop, with ease. However, it seems I might have some trouble now!
Is this the famous nVIDIA issue? I've heard a few times that it is only a driver issue. I didn't pay attention to that, cause I thought it would be a minor problem. Anyway, I want to know more about it. What is the problem? And why? How many things are affected? Hopefully, only 3D is a problem. Is there any solution? If it is only a problem of driver, why don't Apple or nVIDIA publish a new driver or patch to solve it once and forever. I actually tried to find a driver for the video card, but I don't think it exists, at least on nVIDIA's website.
I noticed that some people had very similar problem with Simcity 4, but the suggestion was to find a patch for the game itself instead of waiting for the expected Mac OS update, and that was a long time ago. So the problem is still there seriously affect the performance, while no efforts have ever been made to solve the problem?

Did you follow the wiki guide?

NVIDIA issue: Apple not agreeing to replace logic board

Hi,
I have a 15" MBP purchased in Oct 2007.
This is what happened.
Watching videos, screen starts flickering, Then hanged. So rebooted manually. Happened 3-4 times and after that system won't boot.
Display comes, sound comes and then comes to gray screen of death.
Took it to ASP, guy says software issue and asks me to repair. I go home run the diagnostic test and get the error:
4VDC/1/40000003: VideoController.
Googled and found out about the NVDIA 8600M graphics processor issue.
Went back to ASP very happy that problem occurred with just 2 months remaining for the 4 yr warranty.
Then begins my ordeal.
ASP says because of the kernel panic, they cannot run any diagnostic test to confirm if its only GPP issue. They say some other component on logic board has failed so cannot give free replacement.
Raise it with Customer care who puts me through Customer Relationship Manager, she says she'll have Apple engineers validate it.
Comes back next day, says Apple engg ran test and found out its not GPP issue. I ask for results confirming it. She says I can get those from ASP.
Next day go to ASP, ask for results, they say we could never run any test.
I am a bit of technical guy myself. I understand that any malfunctioning hardware can cause kernel panic and graphics processor is pretty important one.
So what I don't understand is, how can Apple say its not NVDIA issue, without even running any test.
Called up customer care again, (this time was connected to different relationship manager) she kept saying the same thing, we did our test and find to connection to GPP issue. I asked her to put me through some technical person. She said she would do it and am waiting for the same.
What I find very frustrating is that I have found many instances where people found the same issues as mine and they got a free replacement of the logic board. Then why in my case Apple is not willing to accept that this is the same problem.
I need help from folks over here. What really are my options? What should I do?
I am hoping the Apple technical person understands what I am saying. But what if he too refuses to accept?
I cannot afford to spend this much on a logic board. Will have to buy a new one and that too non-MAC. (My wife would kill me if I buy another MAC and based on my own experience I would be very scared as well)
I am based in India.
Please help.
-Thanks

Finally some good news. Couldn't wait to share with you all.
Received a call from AASP that they have got the approval for replacement of logic board and I should be getting my laptop back next week. Yayyyy..
This is what happened today.
Today being a holiday I went there in the afternoon. Luckily the place was empty. So caught hold of the supervisor and told him lets sit together and work on the
issue. Told him if we suspect the kernel panic to be an OS issue then lets hook up another HDD and bootup the laptop. Thankfully he too obliged.
First thing he booted up in single user mode and ran fsck. HDD was all OK. Then I noticed that the background instead of being completely black had some blue
colored stripes. He probably noticed that as well but didn't say so. When I asked him if it was supposed to be black he said yes but also said it could be an OS
issue as well. Then he got an external monitor. But since the laptop won't boot we couldn't reach the stage where we can make use of external monitor.
Next he brought external HDD. It was detected but again laptop won't boot from it.
Then he got the NVIDIA Test Program on a USB stick and tried to hook it up. Unfortunately the laptop didn't recognize the USB stick. He then got the specs of
my laptop from Apple Site and brought up the TS2377. Then he gave me some nonsense about how my model was 15"MBP 2.2/2.4 GHz (Late
2007) whereas in TS2377, it just says 15"MBP 2.2/2.4 GHz, no mention of Late 2007, therefore my laptop is not part of affected batch. I was like, dude, what
are you talking about, its clearly mentioned manufactured between May 2007 to September 2008. Then he said, this model doesn't have "something" because of
which the NVIDIA test cannot be run. When I asked what that something is, then he just said nothing and cut short that thread of conversation. Then he tried to run
the test on his own laptop and to my good fortune even that laptop didn't recognize the USB at bootup time. It would detect when system was running. At
that point he pretty much ran out of all excuses and told me he would take the laptop inside and work on it. He told me he'll give me a call once he has an
update which he did a while back and gave me the fantastic news.
Although I am thankful to this AASP person for looking into it seriously, this whole episode has left a bitter taste about Apple's service in general.
First I never expected Apple product to go bust in less than 4 years. And if there is a known manufacturing fault then Apple should make sure that the
customer doesnt have to do running around to prove the issue.
The NVIDIA test requires the system to boot up. But ideally the test should be such that they should just be able to take the logic board and verify it somehow.
Its like, if the part has gone little bad then we can replace, but if its gone completely bad then we can't.
Also, Apple should look to fix issues in logic board rather than asking users to replace it completely (in the event they are not providing replacement). For all
we know the problem could be in $10 component that requires a $1000 to replace.
Anyways, enough of my rant. I'm just relieved that matter is resolved. I am thankful to all who replied esp tjk.
Wow.
As you and I already know, that machine is indeed one of the models that may be affected by the NVIDIA issue. It's difficult to believe someone would deny that. Anyway, your persistence paid off, and you should be on the way to a normally functioning MBP. Finally. It's too bad you had to go through all that, but I'm glad that worked out for you. Hope you'll post back with the results after the MBP is repaired.

IMac 3.06ghz with Vista 64bit :: Need drivers for GPU nVidia 8800 GS

Hey everybody,
I succesfully installed Vista 64bit on my newest iMac with Boot Camp, but the only thing missing right now is the driver for the GPU, Nvidia 8800 GS 512MB RAM. Any idea if I can install a fitting driver? I already tried the auto-detect driver from Nvidia's website and I manually selected the latest driver there, but none works.
Any ideas?
Thanks so far!
Mx

Hi Mx,
use the driver and modification found here: http://www.laptopvideo2go.com/
Since the iMacs don't use the Desktop versions but rather the Mobility versions of GPUs, the generic NVIDIA driver won't install because of the missing entry in the .inf file.

BIOS UPDATE for GE 60 - GE70 0ND (GPU BOOST ISSUE)

I and some of my friends have GPU boost issue with MSI GE60 and GE70 0ND ... (GTX 660M) in TURKEY
We also have a forum for this issue and number of members increases day by day.
We have E16GAIMS.513 BIOS in our notebooks.
One of our friends sent his laptop to technical service and they downloaded newer BIOS 514 (WIN8)and this GPU issue is solved.
However, since there is no update for 514 BIOS in download tab, we cannot update our BIOS and GPU issue continues.
Can you upload this newer 514 BIOS update to download tab as soon as possible.
We are expecting your positive answers.

Quote from: pshywar on 30-March-13, 04:35:40
I think we should wait that this update is uploaded to main website in order to prevent some compatibility or etc issues.
BIOS update is a important issue and it can causes irrecoverable problems. So, we continue to wait
That's a good point; while I got back I was thinking of flashing it but had a re-read of the step-by-step guide before doing so and thought otherwise. Best wait for the official one, that is if they release it.
I'm also going to contact the customer service support to have this included in their download section. I made enough noise for them to update the HD Audio drivers, so here's to this getting the inclusion as well.
Quote from: Prema on 30-March-13, 05:59:24
It was a test, they may never publish it...
But they included the latest BIOS in the Topic Creator's friend's Notebook. Hopefully, if enough noise is made, they will publish it.
Quote from: darkhawk on 30-March-13, 09:47:09
Here's my thoughts. And you probably won't like them.
Try upgrading using that BIOS. What's the worst that could happen? You brick your machine? Make sure everything is backed up, and try it. You want the VBIOS portion fixed so it boosts? Well.....try that BIOS. And if it doesn't work or bricks the machine, you'll need to send it back anyway and they will probably load the BIOS on it then anyway.......
Either way, it's a win (albeit, in 1 situation it might take a few weeks....). You'll get what you want.
I obviously can't try it as I don't have a GE60.....
I think it might be best to just wait for the official one, as the warranty services in Australia are absolutely poops, be it any make or brand - most companies are not obligated to have the customer's best interest at heart, so if they can get away with voiding it, they will - so I'm not too keen to test this unofficial one lest it affects my warranty.
Thanks for your input though, nonetheless, darkhawk.

Early 2008 MBP screen turns off/on (not NVidia issue)

My MBP is an early 2008 A1260 15" and the screen suddenly turns off and on. Originally I thought it was the NVidia issue but that doesn't seem to be the case because I can hook up an external monitor and get video. I took it apart to check any loose video cables on both the logic board or behind the screen itself and everything seemed intact. I even pushed everything firmly in to make sure the connections were making good contact. The backlight also lights up but without any image so the inverter is not to blame either. Then as I figure it's simply the LCD that has gone bad and i'm using my comp through the external monitor the screen suddenly turns back on and works. Later shuts off and back on. This makes me think it's a faulty cable however everything is connected properly and there were no signs of damage to the video cable.
Any suggestions as to what to check or this could be? I don't want to pay nearly $150 to replace the LCD screen if that's not it. :/

Allow me to elaborate the situation...
Taking in to Apple = $350
Purchasing a new display and replacing it myself = $150
New video cable = $30
Taking it to Apple = No.
I can fix computers on my own but I am a bit stuck on this slightly odd situation so I would greatly appreciate any replies to not include the response, "Take it in to Apple."
I appreciate the suggestion but that's not going to happen after I already took it in thinking it was the NVidia issue and there found it was a display problem.
You're right that it seems it's a component that's failing but that's why I am asking, which other components should I check? Any other similar issues? Etc.
Thank you

NVIDIA Issues; hitting the video card hangs the machine

Hello everybody, this could easily be placed under the Kernel and Hardware forum, but this one suits my experience level better. I tried
searching for some similar issues to what I am having, but wasn't able to come up with anything. (Perhaps I was an unknown keyword off in my searches. )
Additionally, thanks in advance for any help! I'm pretty much out of ideas short of replacing some hardware.
My problem is that whenever my desktop displays anything that is graphically intensive, it freezes. I first experienced this while I had Slackware 13.1 installed when trying to run Minecraft. I had been running it successfully for a month or two when it hung while I was playing. I switched over to Arch in the hopes that it would be easier for me to troubleshoot the problem. This was a few months ago, and I've not been able to figure it out.
I'm running with an i7 930 CPU, GTX 480 video card, and six gigs of RAM. My xorg.conf is below:

The more I investigate, the more I feel like this could be a hardware problem. I checked the CPU temp first, but it only reaches ~32 degrees celsius when the system hangs, so I doubt that's the cause. I've checked the cables (power and otherwise) between everything in my box, and it's all solid. I've also taken the sides off, thinking it my be an air flow issue, but that didn't solve it either.
On the software side of things, I've got nvidia, nvidia-utils, and lib32-nvidia-utils installed and they aren't popping any errors that I can see. When I run glxinfor or glxgears, nothing happens, the terminal just prompts me for input (which is actually an improvement, in Slackware, they hung the machine).
Again, any help on this issue is greatly appreciated, I'm at my wit's end about it.

I had a similar problem that turned out to be the graphics card working itself loose. So, if you haven't already, try taking it out, cleaning the contacts and plugging it back in. Worth a try and worked for me
Also, Xorg 1.10.2 & the nvidia proprietary driver don't seem to be in conflict for me so I think williewillus is mistaken.

Yosemite NVIDIA issue on MacPro 5,1

I'm getting visual noise and screen rendering errors. It started when I upgraded this Mac Pro 5,1 with an SSD drive and fresh install of Yosemite 10.10. I had previously been using 10.8.5 on a conventional drive with no issues. The graphics card is an NVIDIA k5000 attached to two 27" Apple Displays via display port and a 50" Panasonic video monitor via HDMI. A few dozen times each day I'll see interface noise (see example in attached image). This occurs in my most used apps, including Finder, Premiere Pro, After Effects, Photoshop and Safari. This problem only occurs on the Yosemite OS on the SSD drive.
I am using the latest drivers from NVIDIA; CUDA Driver Version: 6.5.18 and GPU Driver Version: 10.0.43 310.41.05f01. I downloaded the NVIDIA Driver Manager. Selecting and restarting using either the "NVIDIA Web Driver" or the "OS X Default Graphics Driver" does not resolve the problem. I've also tried enabling ECC which does not solve it. I then replaced the K5000 with the original ATI Radeon HD 5770. The ATI does not have this problem, only the K5000. I then thought the card was dying or becoming defective, which didn't make sense because everything is clean when using the boot drive with 10.8.5. Despite my reservations, I purchased a new PNY made NVIDIA K5000, the same as the first, and the problem persists. The K5000 cards are not defective as both of them always display a clean interface in 10.8.5. It is clearly an issue with the K5000 on a MacPro using 10.10 or 10.10.1.
Anyone else experiencing GPU issues like this on Yosemite? I've seen many postings about other GPU issues but mostly with laptops. Apple or NVIDIA, are you aware of this? Also, where can I submit a bug/issue report to Apple and NVIDIA?

I'm having the same problem (and more) on my 2014 Retina MacBook Pro running Yosemite 10.10.2.
Two days ago the CUDA Preferences panel said there was an upgrade, and installed CUDA Driver Version 6.5.36.
In Activity Monitor "aerendercore" shows as "not responding" around 10 times a day. Premiere crashes 2-3 times a day.
I checked nvidia website, and they had a 6.5.37. Installed that, but same issues.
CUDA Panel also says "GPU Driver Version" is "10.2.1 310.41.15f01" ... not sure if that is something that can be updated.
I'm rebooting 4-5 times a day.
Not sure what to do ... have you had any luck?

LR crashes related to the GPU + KB3048761 issue

Summary
========
There is the chance to have LR CC problems if you install the MS KB3048761 update
When LR has issues with the GPU, it doesn't warn you about that, it just crash! We need a better error handling and UX here!!
LR crashes when just disabling the GPU!! Same recommendation as above.

When I started to use LR CC, it crashed (perpetually frozen) very often; in particular when entering into the developing mode. Also, I have a crash with PS CC, and it told me in a popup window it was because the GPU. So, I disabled the GPU in PS & LR CC and as result no more crashes!!
Then, I ran the Windows 7 (64-bit, SP1) update panel and found out an nVidia update, and other one (KB3048761) related to memory-leak issues when multiple windows are open.
I installed both of them and started to have issues with LR CC temporarily frozen each few second of interaction. I had to switch to another application to go back to LR and have response form it. However, PS and all the other applications I use (Google Chorme, MS Office, etc.) were fine. Then, I de-installed the KB3048761 update, and the life was beautiful again.
I felt it was the moment to test the GPU, and enabled it in both LR and PS CC. LR still got frozen from time to time but not very often as before. However PS is fine all the time! I decided to disable again the GPU in LR CC, but it also gets frozen when I just try to disable the GPU!

Whatever the cause is, it will likely not fix itself, but continue to get worse over time. You could try running the extended version of the Apple Hardware Test to see if anything turns up.
Since you're under warranty, you might want to go ahead and report the problem to Apple and maybe get a case number. Very likely the problem will slowly get worse until it happens so frequently that it will predictably happen when the computer is started up. Apple would probably like to see the problem occur before doing a repair.
Of course if you get an error code from the AHT, you would have something concrete to report.
There have been some problems with the GeForce 8600M GT chipset specifically. You might want to check in the system profiler to see if you have this particular chipset.
It could also be a problem with your inverter board or possibly the cable.
Good luck!
