Why my mac keeps freezing

I have a macbook pro 13" from mid 2009. I had 2gb of internal memory and I decided to change it to 8 gbs. Now my computer keeps freezing and a message keeps appearing in different languages saying my computer needs to restart. How do I fix it?

That message is called a kernel panic, and it's almost certainly caused in this case by a hardware issue. Perhaps you got bad RAM, or perhaps the wrong RAM, or perhaps it's not seated properly. It's even possible you damaged something during installation.
Where did you get the RAM, and what are the exact specs of that RAM?

Mac Keeps Freezing When Internet Browsing

Hey guys,
I don't know if this'll help but all the threads I usually go on, the person with the problem usually gives their computer details, so:
- OS X Yosemite 10.10.1
- iMac (21.5-inch, Late 2012)
- 2.7 GHz Intel Core i5
- 8 GB 1600 MHz DDR3
- NVIDIA GeForce GT 640M 512 MB
Well, anyways, now to the problem;-
Lately, whenever I'm browsing the Internet on Google Chrome of Safari, 100% of the time after about 10 minutes it will always freeze for about 30 seconds, then go back to whatever it was doing. It will do this a few times until it freezes for good (spinning rainbow wheel), and I actually have to turn off the computer.
In the past, I have accidentally installed an adware called Genieo, which I got removed when I went to the mac store. I'm not sure if that's come back to haunt me, or I have done something else stupid while browsing. I haven't installed any software applications recently, which has got me confused as to why my mac keeps freezing.
Also, if I'm browsing on Google Chrome and it doesn't freeze, shockwave will always crash whenever I try to view something, then it will freeze.
After this, when I try to turn my computer back on, the kernel on the white screen will always come up, which I then have to manually turn the computer off again. It usually turns on normally after a few times of trying.
I've gone onto Recovery Mode and verified my disk many times, to which it says there are no problems.
I've looked up Antivirus' for mac, and have come across a few (Avast, CamXav, etc), but I have also browsed many forums with the majority of people saying your mac doesn't need an antivirus and it will slow your computer instead of benefiting you, so I'm not sure what to do.
Just wondering if anyone else has come across problems similar, or know how to fix this. Should I install an antivirus? Should I go to the mac store (last resort)? Will reinstalling OS X or restarting then booting up from Time Machine with my external drive help?
Thanks.

The suggestions in the 2 links I previously posted did not work?
If you have Apple Care, call them & let them deal w/it.
OOW, try the following:
1 - set up a test account. You need to determine if the problem crops up in the test account. This will determine if the problem is system wide or not.
2 - Run Apple Hardware Test. Make sure when troubleshooting you have disconnected all devices from your comp except for the keyboard.
3 - Run OS Recovery again. Only this time select "Repair Disk."
4 - Reinstall the update. Only this time use the OS X Yosemite 10.10.2 Combo Update
5 - Take your comp to your local AS or an AASP. Diagnostic testing is FREE!

Why my preview keeps freezing when I make several underlines in pdf file? It keeps saving and freezing.

This is my first time posting here, so I'm sorry, I re-read my post several times and honestly did think I provided enough information, but you're right, it wasn't the right kind. So please (continue to) bear with me, I'm really not trying to be ignorant. I honestly assumed the issue was something I was doing wrong in Bridge, nothing to do with my computer specs.
I am using a late-2008 Macbook, running Yosemite 10.1.1 (screenshot below)
On the Mac I am using Bridge CC 6.1.1.115 and Photoshop CC 2014 (2014.2.1 release, 20141014.r.257 x64)

Is there any information you need that I missed? I'm trying not to be a dingus, but I'll have to ask you to be patient with me in the meantime. I haven't ever looked up half the hardware/software details that were suggested and I don't know how to off the top of my head, so I provided what I already knew how to

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

My mac keeps freezing...How can I uninstall lion?

My mac keeps freezing on me, particularly when Im on safari. The most annoying part is that it happens three or four times in a matter of an hour, and then Im prompted to submit a report that feels like a joke considering that we have yet to see an update for lion solving this issue, and the problem persists. How can I uninstall lion and get macs previous iOS back?

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

Hello TracyOShea,
It sounds like your Mac is becoming unresponsive for no apparent reason. I recommend starting by resetting your computers SMC:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
Then perform a Safe Boot, and then restart the computer again and retest the issue:
OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/ht1564
To start up into Safe Mode (to Safe Boot), follow these steps.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without holding any keys during startup.
Thank you for using Apple Support Communities.
All the very best,

Why my ipod keep freezing

why my ipod keep freezing all the time

I had this problem with my old 20GB classic ipod, it all started when I began using my ipod for my running trainings, every day it used to get worse freezing every 10 minutos or so, then I got ****** and bought a new 80GB classic Ipod, I have it for about 3 weeks now and guess what? It started freezing or skiping songs also. I did a test where I synced the same library on my both ipod and the songs being skipped on my new one wasnt being skipped on the old one, so its a problem with the song, then I though it could be any damage in the ipod HD but my new ipod has no reason to be damaged, the only impact that it might have recived is from my running trainings, but the impacts are really weak. Other test I did was trying to remove the song being skiped from the ipod, everytime I did that my ipod couldnt be ejcted, it kept showing me the following message "The ipod canot be ejcted because it contains files that are used by another aplication." I had to unplug my ipod without ejecting it.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does my Mac keep freezing and applications not responding?!?

Hello everyone, I have a mid 2009 MacBook Pro, 500gb HD, 4gb ram. The problem is that it keeps freezing. I am writing this on my iPhone because my laptop would probably just freeze up if I even attempted to open an application. The problem is that my laptop won't stop freezing up. As soon as I have any application open, it will stop being responsive, give me the beach ball spinning wheel thing, and I'll use command-option-escape to open the force quit menu (because at this point the mouse usually can me moved around the screen but just makes the system get worse) to force quit what ever applications I have open. Then finder will stop responding, and then nothing will work until I do a forced shut down (hold the power button down) and turn it back on again, where the same thing happens within a minute. I tried repairing permissions and doing a P RAM reset, but have had no success with either. Please help, this is ridiculous, I can barely use my laptop and I need it for school. Thanks,
-Dylan
