My mid 2010 macbook pro keeps freezing/crashing every time I try and play a game. Any help?

Every time I try and play either WoW or The Sims, my mac goes to black screen, or black screen and repeating last second of noise it was playing. I haven't upgraded to Lion and am still using Snow Leopard(??). I am by no means the most tech savvy girl in the world, but would appreciate any help, as this is driving me insane!! Thanks!!!

I don't know if it would help, but this is all the whoo haa from the last panic report thing. (about 5ish minutes ago)
I don't really know what any of it means, but if someone could help me decipher and tell me if there's anything I can do, I would be super grateful. (before I go into apple, that is)

MacBook Pro has no sound at all. Called Apple and they said to reinstall OS X.

I have recently discovered that my MacBook Pro has no sound except for the startup chime. I called Apple and they told me to reinstall OS X because something went wrong in the OS. Is there any other way to fix this?

That's a really overly simplistic answer to your problem. Re-installing OS X doesn't always fix every problem. Yes, it might in your case, but it might not. Are you still under warranty? Either way, I'd take it into your local Apple Store and show them the problem and let them fix it. If the system has to be installed anew, so be it. But rule out other problems first.
Before you do anything, make sure that you have a back-up of your data, applications, etc. If you don't already have a back-up scheme, get an external hard drive and use Time Machine to back up your computer. Then take it into the Apple Store.
Good luck,
Clinton

Why don't you contact the online store's customer support?

Downloaded 11.0.3 (42) 64 bit to my MacBook Pro and it crashes every time I select a song a use the 'add to' function to add to a play list. It's never done this before, is it a bug with the new version?

You could just disable updates. Change these settings in about:config.
* app.update.auto - set to false
* app.update.enabled - set to false
You can still check for updates with the "Check for Updates" button in the About Firefox window, but it will download the update file anyway if there is an update available. You can also check which is the current release from here:

Why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor?

why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor? it only works if i turn the computer on with it already plugged in.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC
<About NVRAM and PRAM>
<Intel-based Macs: Resetting the System Management Controller (SMC)>
Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

My MacBook Pro has no sound, but the volume setting works

My 15' MacBook Pro 2012's sound is not working. You can still change the volume by pressing F10 to F12, but not actual sound comes out. The headphone jack is not red (although I have experienced that problem before and fixed it). Whether the headphones are plugged in or if they aren't, there is still no sound. I am running on OS X 10.7.5 with a 2.6 GHz Intel Core i7 Processor, 8GB 1600 MHz DDR3 Memory and the storage capacity is 749.3 GB total.

Have you tried a PRAM reset?

Macbook pro has no sound, any ideas on the cause?

My macbook pro crashed while watching a video and since then has not had any sound coming from the speakers, although it did emit the startup sound when I restarted it.

One of these steps may help.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers
    Make sure that Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

Macbook Pro has no sound and needs to reboot after sleep-mode.

A few days ago, a friend of me wanted to do an hackintosh on his computer, i didn't like this idea but i helped him.. I had to install a so called program osx86 and multibeast and uniboot.. After all we didnt do the hackintosh at all but more important i removed the program and files but then suddenly my sound stopped working, i had this problem before with the red light but this was something different, at sound in my preffences there are no input or output devices not even my speakers or microphone.. After that i couldn't set the macbook in sleeping mode because it can't go back to normal anytime.. only when i hold the power button.. also when i start the MacBook i get a message that the computer restarted because of a problem every time! Please help me i don't know what to do..
I've read some pages with this problem that you have to upload your kernel message in console so i did this i got 5 of them this is only 1:

Thanks!

The last gasp is an OSX reinstall. If that fails, then the genius bar is the best option.
Ciao.

My MacBook Pro has no sound, even with Apple headphones plugged in...

My Macbook Pro won't play any sound from both it's own speakers or any speaker I plug it into. This has me very worries, please help.
-Thanks

If a PRAM reset fails to correct the problem, bring the MBP to an Apple store genius bar:
