MBP 15" intel core 2 duo keeps crashing with distorted screen

Why does my macbook pro 15" intel core 2 duo keep on freezing or crashing with a distorted screen?
It doesn't seem to give any pattern when it randomly crashes. According to the hardware test, there's no problem.
But after doing the full hardware test everything seems ok again for a few days then crashes again with a distorted screen. Has anyone else out there experienced this as well? Help please!

Like i said in the first post, i already did the SMC reset. This is very strange because sometimes the macbook can stay up with no problems for a very long time, like 24 horas staright and nothing happens. Than i put two 720p videos that have a 30 minutes duration and nothing happen also. The fans worked like **** but it keep together. So i don't know. Does the graphic card have a so random behaviour like that? I can't find the scenario that triggers that black bars and freeze it happens from time to time.
Can somebody help me? At least to find out what triggers tha behaviour.

I have a 5 year old MBP, 2GHz Intel Core Duo, 1GB MHz, DDR2 SDRAM, running Snow Leopard, 10.6.8.
I use wireless to connect to the Internet and everything works fine when I sign on. After being on line for awhile and my remaining battery power at about 60%, I lose connectivity. I turn off Airport, restart it, and I am asked for my secure password. I enter the password but cannot reconnect. So, I shut down the computer for 5 to 10 minutes, restart, and everything works great again.
Has anyone experienced this behavior and do you have any suggestions as to what is causing the problem.
Thanks for any help you can give me.

I think I hit the wrong key ... so here it is again!
Thank you ... I keep seeing this i5 and i7 processor mentioned and it is also recommeded that I stream using it. Do you have any suggestions on which MacBook would serve me better? Or is there an upgrade of any kind that will help me?
Thanks again.

My Imac 2.0 GHz Intel Core Duo keeps powering off

Hi all,
I have a 20inch 2.0 GHz Intel Core Duo (Imac 4.1), Over the last few weeks the Mac would just power off on the odd occasion when using Apeture, I put this down to being the just overworked for processing picture. This seems to have been getting worse and kept occurring more and more often. Light Internet browsing was fine..
I decided after some time to replace the 2gb memory i had to see if that would fix the issue, this seemed to work for a few days then the same issues returned.
I now seeing this issue occured just by opening Safari and decided to rebuild the Imac, I completed the Snowleopard install and all seemed ok for a day then it re-occurred again and seemed to be worse, I then removed the 2gb memory and just kept with the 512mb as when bought... Still it keeps powering off. I have moved to different power sockets and still see the same issues.
Please note in order to power the Imac backup up I have to leave the power out for about 20-30 minutes, If i leave the power plugged in it never boots backup up.
I now decided to even revert back to Lion OS, but it just powers off during the install...
I thinking it sounds like a Power supply issue but would like confirmation before I take it to a repair shop..
cheers
Dan.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET

Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

Will Intel Core Duo image work with Intel Core 2 Duo image

I soon need to start preparing an image for the next school year since we are soon going to start moving into a completely new campus which images will need to be ready for lab imaging over the summer and the sooner I can have a lab image ready to be tested the better, but my question is......
If I create an Intel image on a "Intel Core Duo Processor " which we have currently, to then create this image and then push out two two complete brand new labs of what will be "Intel Core 2 Duo Processors"
I know in the past I have created images on the highest PowerPC computer (G5) and had the image on G3's, G4's, G5's etc. an work. I'm not sure if the difference in the processor will require the image to be made on the very same computer or not. If so, we will need to purchase one.
Anyways..... just wondering if someone has already tested this or played around with it?
Thanks,
Carter

The build version on the Core Duo models is not the same as the build version on the Core 2 Duo models. These individual builds are customized for their respective hardware. The only version of OS X that will be common for all Intel models will be a public build version that supercedes both custom builds.
The extant builds are here: http://docs.info.apple.com/article.html?artnum=303315. However, the table does not include the latest Core 2 Duo MBP.
If you upgrade all Intel Macs to 10.4.8 then an image of that version of OS X should be common to all Intel Macs.

MacPro 1,1 keeps crashing with grey screen

My mac pro model identifier MacPro 1,1 keeps crashing with a grey translucent screen that comes down over my view. It's happened 3 times now, twice today. The problem report for the crash after reboot both times today read: "TLB invalidation IPI timeout: " "CPU(s) failed to respond to interrupts. unresponsive CPU bitmap: 0x8, NMIPI acks: orig: 0x0, now: 0x0"@/SourceCache/xnu/xnu-1699.32.7/osfmk/i386/pmap.c:3024"
I have backups of everything on 3 other hard drives that are in my mac pro, so I'm not too worried about losing any data, I just want my computer to function properly, I know it's old but I still love it and hope she keeps ticking for awhile!
Any help is appreciated!
Thanks!

The panic originated in Dropbox, but you have several third-party extensions installed any of which could cause an incompatibility. Try running for a while in Safe Mode to see how it goes and if the panics stop.
In the future post the panic logs in text.
To post screen shot do this:
Press COMMAND-SHIFT-4 which will change the cursor to crosshairs.
Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
Release the button and the image will be saved to your Desktop.
Click on the Camera icon in the toolbar of the forum message editor.
Drag the image onto the Choose File button and click on the Insert button.

My iPad air either keeps crashing with blue screen or reboots it self. Other times it just locks up. It does not seem to matter what program or process I am doing.

Macbook Pro Intel Core i5 keeps crashing

My Macbook Pro has been slow lately and it crashes at least twice everyday and I have to force it to shutdown. When it crashes, the screen freezes and only the mouse moves. The clock is not moving and same with the power percentage. I usually have Spotify and Chrome running. Chrome will pop up a message saying that scripts is not responding even though it was just Facebook. What can I do?
Specs:
MacBook Pro 15-inch, Mid 2010
Processor 2.4 GHz Intel Core i5
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce GT 330M 256 MB
Software OS X 10.8.5 (12F45)

Hi,
My Mac will freeze and only the mouse will move. The clock at the top of the bar will not move and same with the power percentage. I can some how click on the application screen but it will take a long time to move. Bascially everything is very slow and it barely moves.

Logic 9 keeps crashing with white screen flash!!!

Hi all,
Lately Logic has been crashing consistantly every 15-30 min since updated to 10.7.4. It has become absolutly unbearable now and is constantly ruining work and flow. Everytime it crashes a white screen flashes up and if im lucky i can save just in time before it completely freezes and the rainbow ball of death starts spinning. I have to then force quit logic. The crashes happen randomly in time and in task. The one reocurring act that i've found it tends to crash alot on is when trying to move some in the arrangement or the piano roll. I have no idea what the problem is and would post a crash report but since im force quiting EVERY time i am unable to obtain one.
Is anyone else experiencing the same problems and if so is there a fix.
MRADERZ

Repair Disk Permissions did not work but so far so good on reinstalling the update.
Seems to be working fine on my macbook pro.
No crashes since reinstall so will do this on my imac when i get home from work.
Fingers crossed works the same as it is my main producing computer.
Thank You AnaMusic unbelievably appreciated.

Imac intel core duo (2008) crashed and wont reboot after Mountain Lion upgrade

Hi can anyone help?
Hi, my imac was loaded with Snow Leopard and I upgraded to Mountain Lion a few days ago and today when I got back from leaving it a few hours the screen went funny!!! (see pic) and it wont reboot. The same screen appears straight away when restarting. I have tried holding down the shift for safe start but it didnt work and also a nv/ram pram reset (but only heard one 'mac sound')
I have my old snow leopard disk..............somewhere!!! but I'm not sure if I can boot from them if I have just upgraded to Mountain Lion via the app store download??
I didnt do a boot disk! (yes I know) or a back up (yep again...I know!) so if anyone has any ideas on how to help :-) I'd be very grateful!!
Thanks Melanie
PS is the problem called a Kernel Panic????

I'm afraid my next piece of advice you won't like. I think you need to erase the drive and reinstall Mountain Lion from scratch.
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on
the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button and set the Zero
Data option to one-pass. Click on the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Hp3400 keeps crashing with blue screen with clean windows 7 64

Hi,
A brand new hp3400 mt (with product number LH121EA#ABU) crashed during the initial setup process for win 7. Eventually I could boot to windows, but then it kept crashing. Since then, I have reformatted and reinstalled win 7 64, and downloaded and installed some drivers from your support site for all relevant hardware (I think), but not software.
I ran memtest on the ram and it is fine.
I can now boot to windows (although it took a number of runs through the installation process, with crashes occurring intermitently). I can navigate for a while, then things hang up (e.g. clicking Device Manager in Control Panel takes 4 - 5 minutes to open, if at all). The crashes occur randomly, e.g. when browsing the web or installing an update. After restart the crash recovery notification reports errors with BC Codes of 1a or 50 (if that's any use).
Please help! I'm at the limit of my knowledge now!

In that case you need to check with the Memory (RAM) and the Hard Disk Drive.

Any video played in my firefox will always blink. My operating system is Mac OSx 10.6.8 running on intel core duo. 32 bit machine

Everytime I view videos on firefox, it keeps on blinking. The issue is not reproducible on Safari. My MacBook runs on intel core duo 32 bit with 1gb RAM

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows:
#* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux.
#* In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
#In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

I'm investigating whether I can take on 'Lion' when it's released. The information states that your mac needs Intel Core 2 Duo. Is this the same as '2 GHz Intel Core Duo' which is what it actually states my mac has?

I could not agree more! My MBP 2007 Intel Core Duo has had its logic board replaced not to long ago (DVI port died). The original hard drive is running great and I am running Snow Leopard wonderfully.
I was amped during the keynote and am really looking forward to Lion. I know the community is working hard to uncover a workaround because at present time, the solution (by new!) is not a worthy one. Especially when there is literally, nothing wrong with my existing machine.
Apple, please ensure Lion will be available for Intel Core Duo machines, we are not that old! The closed architecture approach produces quality hardware. 4 years is a toddler perhaps teenager when it comes to apple hardware and technology. I predict I have at least 3-4 more years left in my current MBP 2007 machine.
Much Love, Apple!

Window server on intel core duo

is window server installed on intel core duo.how it is installed

Perhaps you are misunderstanding something about Apple computers.
All Apple computers, including those with the Intel Core Duo processors, come with Mac OS X as the preinstalled operating system.
Only recently, Apple has released a beta version of Boot Camp, which is software that will allow you to partition your hard drive for the purpose of installing Windows XP on a seaparate partition, thus creating a dual boot system. Boot Camp includes drivers for Windows XP which allows Windows to run on the Apple hardware.
You can't simply install any version of Windows on Apple hardware.
You need to install Boot Camp first. Boot Camp does not have the drivers for Windows 2003 server, so you will probably not be able to run it successfully.

Upgrading 2006 MBP Intel Core Duo to SSD?

My MBP is starting to become depressingly slow. After some research, it appears I'm maxed out at 2GB of memory!    I was wondering if anyone has any experience upgrading the hard drive to a SSD in the same model as mine? Would I notice a huge difference?
I want to install Lion, but am very nervous it will bring my computer to an unusable creep as I've heard from others.
My model # is here. And my hardware overview is as follows:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro1,2
Processor Name:          Intel Core Duo
Processor Speed:          2.16 GHz
Number Of Processors:          1
Total Number Of Cores:          2
L2 Cache:          2 MB
Memory:          2 GB
Bus Speed:          667 MHz
Boot ROM Version:          MBP12.0061.B03
SMC Version (system):          1.5f10
120GB Serial ATA drive @ 5400 rpm
Thanks in advance to anyone that can give info/advice/links, etc. I've never actually upgraded a hard drive before so any tips would be much appreciated!

There is a common misconception that computers slow down over time. This is just not the case. There is no reason for your computer to run slower today than the day you bought it. There is usually something which causes your system to become slow. Things like low hard drive space and perhaps applications running in the background that you weren't aware of can impact speed. A failing hard drive can also cause problems.
As you currently have a 5400RPM 120GB hard drive, you will see a significant change in the amount of time it takes applications to launch with an SSD. Keep in mind, an SSD is only replacing your hard drive, so it is only increasing the speed of loading data from your drive. It won't speed up your applications (except, again, the drive access time for applications that may rely heavily on disk use). As you only have 2GB of RAM, your system likely pages data to your hard drive fairly often. This is when your RAM is "full" and it dumps some of the data to your hard drive so it can load more into the RAM. When you have a low amount of RAM to start with, this happens more often. As an SSD is somewhat faster, this becomes less noticeable.
Instructions for replacing your drive may be found in your user's manual. You should avoid going with SATA 6GB (aka SATA III). While they will work, the SATA speed on your system is SATA 1.5GB. Even if you get a SATA 6GB drive, it will only run at 1.5GB... so there's no sense in paying for the extra speed. You probably won't be able to find a SATA 1.5GB drive... but a SATA 3.0GB (SATA II) drive will be less expensive than a 6GB drive and it will perform just as well on your system. The drive in your system now doesn't come close to saturating the bandwidth of your SATA 1.5GB controller. So, even with the older SATA 1.5GB controller, you will still see a significant boost in speed with an SSD.
Having said all that... basically, yes... an SSD will make your system noticibly faster, but it will not boost processing speeds for your applications.

I have a mac book pro, 2006 with an 2.16 GHz Intel Core Duo processor, can I update to Lion? to use icloud.

Apple keep telling me I need to update to icloud but I'm not sure if Lion will work on my Mac. I've upgraded to snow leopard which seems to have knackered my .me or .mac account (whatever it's called now), so I don't seem to have any option but to upgrade to Lion if I every want to see my emails again.
Apple say I must have a Intel Core 2 processor for Lion to work...... at least I think that's what they say.
I have a mac book pro, 2006 with an 2.16 GHz Intel Core Duo processor, can I update to Lion?

Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.
If you have a Core Duo model then you cannot upgrade to Lion. You can upgrade to Snow Leopard, but iCloud is not available for Snow Leopard.
Open System Profiler in the Utilities folder. Look for the Model ID in the displayed information. If you have a MacBookPro 2,1 or later then you have a Core 2 Duo model and can upgrade to Lion.
