You are experiencing a Kernel Panic, as shown in Apple kb article TS3742. .
Bad or incompatible RAM is, more often then not, the cause of most Kernel Panics. It could also just need to be reset.
Here's the most used site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step. This link just goes up to Snow Leopard but there are a lot of good tips in there.
Here is a great MacFixIt article.

Why does my Mac Book pro keep restarting

why does my Mac Book pro keep restarting and how can it be fixed

It would be nice if you could include a kernel panic log to verify that your problem is...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:

Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,
Clinton

Why does my Power MAC G4 keep restarting itself after I shut it down?

Hi,
Thanks for reading this.
Why does my Power MAC G4 keep restarting itself after I shut it down?
This JUST started happening only 4 days ago.
Most recent installation was Limewire, but I removed it to see if this problem would go away.
I have 3 internal drives (See drive types below) that all have OS 10 on them in order to be able to boot up from either drive in the event of trouble.
However...
No matter WHICH drive I use as the start up drive... the computer STILL restarts itself after it is properly commanded to shut down.
Prior to the Limewire install... the ADOBE creative suite was installed.
There is a Lexmark X83 printer hooked to the computer, which, it seems doesn't matter if it is left on or off... the computer still restarts itself.
Any ideas?
Thanks!

Hi, Tommy!
If you still have problems, trash the following three preference files, then shut down and do a PMU reset. (PMU reset procedure for the QS is the same as is shown at the link for the Gigabit Ethernet.)

Why does my MacBook CD-Rom keep rejecting my Turbo Tax disc?

Tried x 50 to insert new TurboTax disc. Rejected.

Does the Macbook cd drive accept other cd's?
If the answer is NO, the CD ROM drive is flakey. To verify this, check if a different Mac will read the CD.
On the other hand if your Mac can read other CD's it may be the CD itself is damaged.

Why does my intel imac (2008) keep shutting down?

Imac recently started shutting down. no new hardware/software additions. Happens randomly, sometimes on start-up. Any ideas?

From: Eustace Mendis
Sounds like a Broken Drive...
Most of the times this will be solved with a HardDrive Replacement
although,
you could try this
Restart your Mac and hold down the Command key and the R key (Command-R).
Keep holding these keys until the Apple icon appears.
This indicates that your Mac is starting up.
After the Recovery System is finished starting up,
you should see a desktop with an OS X menu bar and a "Mac OS X Utilities" window.
After you do this, select Disk Utility and run it.
On the next screen,
Select the hard drive in the left hand column,
the First Aid tab on the top, and click on Reparid Disk. (bottom left)
When that is done, click on Repair Permissions.
When that is done, quit Disk Utility and restart.

Why does my Macbook pro 2008 not recognize my external dell flat monitor(TV)?

Hello all ,
Its hooked up with a dvi cable from mac dvi port to dell monitor dvi port. My macbook is running mountain lion.
The Monitor light on the front blinks green and then goes into " power save mode" a black screen.
Thanks for any ideas on how to get this external monitor working.

Reboot, then try this
http://www.ehow.com/how_5811316_connect-macbook-dell-external-monitor.html
I'm really guessing here actually since no one answered your post.
You might find better luck searching on Google "Macbook pro plus Dell monitor" for the most recent information.
The SwitchREsX is supposed to be very capable and enable more resolutions for other monitors besides Apple ones.
I think you can hold option/alt when clicking on Displays in System Preferences for a more complete list of options.
Sorry I can't be of more assistance.

Why does my macbook hang when I restart?

I have to shut down and boot up, restart just hangs.

It helps when you post to tell us which Mac OS X you have installed.
Try booting from your install disc, run Disk Utility.
The startup disk may need repairing > Using Disk Utility to verify or repair disks
Check Capacity and Available at the bottom of the Disk Utility window.
Make sure there's no less then 15% free disk space.

Why does my MacBook Pro and Mac Pro keep freezing?

Why does my MacBook Pro freeze?
MacBook Pro
2.4 GHz intel Core2 Duo
4BB 1067 MHz DDR3
OSX 10.6.8 Snow Leopard
I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
Tried safe boot several times. No help.
Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
Couldn't clear cache etc as couldn't get to the relevant part to do it.
Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said “The volume appears to be OK”. No help.
Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
Cheers

... does Apple products work much better with using Apple routers?
While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.

What is application memory and why does my macbook pro keep running out of it?

what is application memory and why does my macbook pro keep running out of it?

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Please note that if the cause is a memory leak, installing more memory will not help. That's likely if you already have more than 4 GB of memory. Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 and later. Some details may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, reset the printing system. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Why does my Macbook keep going to sleep every 10-20 secs!

Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

Why does my Macbook Pro keep shutting down during installation of OSX Mountain Lion?

Hmm, good luck then!
I'm pretty much exactly on the opposite side of the planet, but I've been to Vermont and remember its rural beauty well. However, I can't imagine you having the only Internet connection within a reasonable radius (where "neighbors" hanging off the same ISP don't count). Uh, that note only if your wired connection to the router produces no good result, either...

Why does my macbook pro keep shutting down with a charged battery

Why does my Mac book pro keep shutting down? I lose everything I am working on when it shuts down help

kva,
which model MacBook Pro do you have? Is it running Mac OS X 10.5.5? If not, which version of OS X is currently installed on it?
Are you running on battery when it shuts down, or are you running on AC when it shuts down, or does it happen in either case? Which app are you working in when it shuts down? Does it happen only in that app, or does it happen no matter which app you’re working in?

Two finger scrolling does not work on my MacBook (late 2008)

Two finger scrolling does not work on my MacBook (late 2008) with either the notebook trackpad or a b/t conected magic trackpad. Yes, I've set system preferences. Suspect a driver or s/w problem. Ideas?

Saw another post that hinted that you need to go to accessibility settings:
System Preferences > UniversalAccess > Mouse & Trackpad > Trackpad Options
Enable scrolling (and I enabled dragging while I was at it and it worked. Looks like wierd things can get set even if you don't mean it to.

Audio line-in not working on MacBook late 2008

The audio line-in on my aluminium MacBook late 2008 has stopped working.
The built-in microphone works like a charm, but when I connect an external microphone the computer does not register sound any more. I have tried with several microphones, and I have verified in the settings that the sound input is set to line-in (I don't know exactly what the setting is called in English, in French it's "Entrée ligne". Anyway, it must be the right one).
One last piece of important information might be that I hear a scraping sound in the speakers when I connect the microphone. After that, nothing.
Is this a hardware problem or is there anything I can do on my own to fix it?
Thank you!

The built in iMic works
I assume that's a typo and you just meant the "Built-in Mic"
when I turned it on a screen came down that said I needed to restart my
computer. So I assume that means some sort of signal is being recieved by
the line in....
I wouldn't call that a safe assumption, it jsut means your computer crashed. Pretty rare for Mac OS X, but it does happen.
Are you using a PPC or Intel based Mac? I'm guessing intel since you implied that you set GB's prefs to Line-In (this can't be done on a PPC Mac). Make sure GB's Input PopUp menu is set to line in and try creating a New Basic Track.
