Mac Keeps Freezing And Restarting

Here's a good Apple T/N on it: Use safe mode to isolate issues with your Mac. While Apple did have a recall on some models that had a bad graphics card you should have seen some odd color or patterns on the screen when doing a clean boot (cold restart). Sadly Apple recall has ended so you'll need to get a new graphics card here. Hold the keys until your Mac restarts and you hear the second startup sound. If your Mac has the T2 Security Chip, hold the keys until you see the Apple logo appear and disappear for the second time. Release all the keys and let your computer boot normally. Solution #4: Try the macOS Recovery Utility.

Hello all,
This issue may very well belong to the hardware threads, but I suspect this to be a software issue.
I've got a Macbook; it's running an Intel Core 2 Duo 2.16ghz, 1gb ram, and 120gb hdd. The issue is that it freezes an unusually frequently amount of time. It will run beautifully for a few hours, then for the next hour (or until I give up trying to care) it'll keep freezing to the point of requiring a manual reboot. When it freezes, it will start with the frontmost application (typically iTunes or Firefox/Safari/Camino), then any other application I try to switch to will freeze as well. This includes Finder, so I am unable to force quit most of the time. After a couple hours have passed, it'll start up again, then slowly decline into uselessness.
I don't recall this issue when I first purchased my Macbook (about 1.5 months ago). It frustrated me enough to first try an 'archive and reinstall' then a complete, clean, re-install of Mac OS X (twice, actually). After the first clean reinstall, I felt that the freezing may have been due to my reinstallation of several apps (a bunch of open-source apps that I use; NeoOffice, OpenOffice, Burn, etc.). So I did the second clean reinstall but without reinstalling any new applications or importing old settings, songs, address cards, etc. All to no avail.
I thought that it may follow that trend of working for a few hours before starting to freeze because of overheating; so I tried 'Fan Control'. Again, to no avail.
On a side note, my hdd is partitioned. One is 15gb for WinXP SP2, and the remaining space was left for Mac OS X. Interestingly, my Windows partition works flawlessly. It hasn't frozen or crashed once yet. I wish I could say that for Mac OS X. In fact, I had tried to write this post twice in Mac OS X before getting fed up with the spinning wait cursor and booting from Windows to write this.
I have tried Disk Utility countless times. I installed the Apple Software Updates immediately after both clean installs, before doing anything else. So yes, I am running 10.4.10.
Please, please, please, any help would be so greatly appreciated. My Macbook is something of a lifeline to me; I can't be efficient in either my studies or my work without my Macbook. So when it's not working, neither am I.

Before we get our hands dirty, here’s a word of warning. If you’re wondering how to reboot a MacBook Pro, bear in mind it’s the last resort when all other methods to unfreeze your Mac had failed. Don’t try it too often, as it may harm your system. No question, your Mac can handle rapid power losses, and your hardware most likely won’t be hurt. What’s at risk, though, is your data because each time you force reboot a Mac, it affects the consistency of the file system. Now that you’ve been warned let’s go.

Symptoms your frozen Mac needs a force restart

  • Applications are not responding
  • The pointer is not responsive
  • Loud fan noise
  • The screen goes black
  • Mac unable to restart

Can you move the cursor? If yes, try this

Before you force restart a Mac, it’s always recommended to first try a software solution.

  • Go to the Apple menu
  • Choose Restart
  • Click Restart in the menu that appears

Two ways to force restart a Mac

The simplest method: hold down the Power button till your Mac shuts down. Press the button again to restart it.

If your Mac hangs for good and the pointer is inactive:

  • Hold down Control-Command while pressing the Power button.

This is an alternative key combination to force restart a Mac. By the way, if you are on an iMac, the Power button is found on the back of your Mac. Voila!

Is Shut Down any different from Restart?

The difference between Shut Down and Restart is quite self-explanatory. When you perform a restart, your Mac will turn on again, loading its previously active apps. As for shut down, your Mac won’t start until you press the Power button again. Interestingly, all new Macs have an automatic reboot feature built-in. So even if you sit and do nothing, your frozen Mac would eventually reboot by itself, though it takes a bit of patience.

How to force shut down a frozen Mac

If you need to force shut down a MacBook Pro or MacBook Air, all you need is again to press a Power button on your Mac’s keyboard.

  1. Press and hold the Power button for 2 seconds.
  2. Choose Restart, Sleep, or Shut Down in the menu that appears.

If you don’t want to reload the baggage of your previously opened apps, tick off “Reopen windows when logging back in.” We recommend you deselect this option when your Mac is slow to lighten the weight on your RAM.

If your Mac won’t shut down:

  1. Press and hold the Power button.
  2. Hold the button until the Mac shuts down.

Needless to say that when you force restart a Mac, all your unsaved projects may be lost. It’s unfair, we know.

Why does my Mac keep freezing?

The obvious explanation is your Mac lacks memory. Or, to put it another way, there are too many active processes running on your Mac. First off, go to Activity Monitor to check your memory usage.

  1. Go to Applications > Utilities > Activity Monitor
  2. Click the Memory tab.

Now, look into how heavily your Memory is loaded. Quit apps that eat up too much memory for no reason. While this may work as a temporary solution, it doesn’t stop your Mac from freezing up again. You can either force reboot your Mac each time or opt for a radical solution. Below are a few more ideas you can try.

More ways to fix a frozen Mac

Restart your Mac in the Diagnostics mode

Shut down your Mac and reboot while pressing the D key. Within the menu that appears, launch the Apple Diagnostics tool. This will check your Mac’s drive for errors. From then, follow the prompts to finish the diagnostics.

Clean up your Mac

Remove old unused apps, system junk, and pervasive browser extensions. For this purpose, try running the CleanMyMac X application on your Mac.

It’s quite effective in removing all junk from your Mac and has several helpful utilities, like RAM free up or app uninstaller. Download it for free here.

Reinstall your macOS

This is the most radical of all methods; that’s why it’s so effective.
