Since the upgrade, my computer is crashing all the time

Question

Hello everybody,I did the mountain lion upgrade a few days ago, and since then, I have a few crashes a day.Does anyone suffer from the same issue? How do I resolve this?Never had this issue before, and now it seems that It&#x27;s something that will not solve itself..What happens is that all of a sudden, I am getting a black screen, and everything is shut down. Then I&#x27;m getting a gray screen saying that there was an error and that my computer is restarting.Like I said, it happens now a few times a day.VERY ANNOYING!!Any ideas?Thanks for your help guys!!

It may be an incompatible piece of thrid party software that opens up via your login items.firast thing I would do is to go to your login items via the user/accounts section in system preferences and remove them all. then restart and see what happens.you should then also creat a new user account and see what happens....Let me know hat hapopens and we will take it from there

Hey Ivan,Thank you so much for your quick reply!! it&#x27;s much appriciated.I&#x27;ve removed all the login items from my user and restarted.Now I&#x27;ll wait to see if there are any crashes.If the crashes will remain, I&#x27;ll create a new user, and followup again.I&#x27;ll keep you updated.Thanks again!

Ivan Clarke1 · Answer

No problem, lets hope it solves the issue.

popole77 · Answer

ok, just had another crash so I guess that the issue is not resolved yet.I will now create a different user, restart and log through the new user.I will wait and see if it resolves the issue.Will update as I move along.Thanks for the help!

Ivan Clarke1 · Answer

Okay so we know it is none of the login items.try the user profile - let me know what happens.next step will be pram and smc reset.

thomas_r. · Answer

When you say you&#x27;re having crashes, what specifically do you mean?  Are you having kernel panics (where a screen tells you in multiple languages that you have to restart)?  If so, the kernel panic log can help diagnose the problem if you post it here.Also, see Understanding upgrade nightmares for some possible causes and fixes.

Ivan Clarke1 · Answer

Okay Thomas I see what you are doing now!good post though....

popole77 · Answer

I guess that I&#x27;m having kernel panics. cause i&#x27;m getting this screen you&#x27;ve mentioned.Is there a different way to approcach this, then to change user? As it&#x27;s a time consuming task to change everything for a new user, only to discover that it didn&#x27;t solve the issue.What are you suggesting?Thanks for all the help!

Ivan Clarke1 · Answer

oh no you dont have to change user you could just set up a new user account to test if it crashes. Thomas has been around a while and may be able to advise on Kernal Crashes better than I

Ivan Clarke1 · Answer

do you have any external hardware plugged in to the mac? if so what?

popole77 · Answer

nope. There is no external hardware connected.

thomas_r. · Answer

Kernel panics are generally caused by a badly corrupt system, bad third-party software or a hardware issue.  If you&#x27;re having kernel panics right after an upgrade, and the machine was functioning fine beforehand, hardware is unlikely (though not impossible).If you post the kernel panic log, it will contain information that can help identify what third-party software you have installed that may be involved.  If third-party software ends up not being the cause, reinstalling the system might help, but we&#x27;ll cross that bridge when we come to it.

is that what you meant?

Okay, here&#x27;s a list of the third-party software that could be causing the problem:com.parallels.filesystems.prlufs          2010.12.28com.parallels.kext.prl_vnic          7.0 15104.778994com.parallels.kext.prl_netbridge          7.0 15104.778994com.parallels.kext.prl_hid_hook          7.0 15104.778994com.parallels.kext.prl_hypervisor          7.0 15104.778994org.virtualbox.kext.VBoxNetAdp          3.1.6org.virtualbox.kext.VBoxNetFlt          3.1.6org.virtualbox.kext.VBoxUSB          3.1.6org.virtualbox.kext.VBoxDrv          3.1.6com.parallels.kext.prl_usb_connect          7.0 15104.778994com.Cycling74.driver.Soundflower          1.5.2I&#x27;ve seen that Soundflower driver implicated in other kernel panics quite a few times, so I would start with uninstalling that.  If that doesn&#x27;t help, I would try uninstalling VirtualBox.  Note that, in both cases, you will need to use the uninstaller provided by the software.  Simply dragging an app to the trash will not do the trick, as that will leave behind the kernel extensions (kexts) that are actually causing the problem.I have Parallels, so that&#x27;s unlikely to be causing problems unless you have a very outdated version of Parallels.  Select the Parallels Desktop app in the Finder and choose File -&gt; Get Info.  What version is it?  I have version 7.0.15104.778994.  (Ridiculous version number, but there you have it.)  If you have an older version, try upgrading Parallels to the latest version.  Of course, if you no longer use Parallels and have no plans to use it in the future, uninstalling it would be a better option.If you end up removing all three of those programs, using the appropriate uninstaller, and see no change, post back here for further advice.
