Increasingly my app crash a lot more often.

Just today xCode has crashed about 5 times. skype wouldn't run at all - I had to re-install as it was crashing on start.

Now I simply can't get a simple little app to run - it's a small app to cut images into tiles. It's crashing at ransom spots half ways through the image processing.

This is starting to worry me as it looks like something is wrong, may it be disk or ram - either way. Any suggestions what I can check or verify any issues here?

Thanks!

Here's the latest tile cutter crash:

First off do you have a backup disk? If not make a backup, make a backup and make a backup. Before you do anything else make a backup. Don't even try the simplest of things before you make a backup. If you care about any files on that drive make a backup.

Now you can try booting with just one RAM module in at a time. You can also use the Mac OS X install disc to run disk utility to try to repair your boot disc. If it does have errors that can not be repaired. I would suggest replacing the hard drive rather than trying to repair it.

Once a hard drive acts at all dodgy. I just replace it. Even if a format and reinstall seems to correct the issue. It just is not worth the risk. If you don't use much disk space I would suggest a small SSD.
 
Backing up is simply a sound piece of advice that I needed to be reminded of. I have now backed up everything of importance - thanks.

I went ahead and ran 2 passes of memtest and 1 pass of apple hardware test. No issues detected.

I will go ahead and try to boot with just one stick of ram now to see what happens if the issue seems to have been resolved without one or the other.
 
Still crashing - both sticks individually. so either both sticks are dud or there's nothing wrong with the ram.

Any additional suggestions to test more than welcome at this point.
 
Re installing will take me probably a full day getting everything back to normal. I can't really afford that amount of time just to test. Are there any disk integrity tools I could try?
 
Did you try running Repair Disk with Disk Utility using the installation disc? You can also Repair Permissions while you are at it.

Since the RAM sounds fine and the motherboard passed the Apple Hardware Test. Odds are it is to do with your hard drive.

As I mentioned before. If you do a reinstall and everything is fine again. I would still replace the hard drive. They are cheap enough and once anything dodgy happens with one I replace it given how prone they are to failure.

For $50 to $60 you can pick up a drive that is larger than what 90% of people have any use for. It's not like in the early 90's where you had to drop $500 for a couple hundred megabytes.
 
Thanks for the link. I did run the repair - no problems to report.
It did find a whole load of permissions to repair though.

I don't know... maybe I do need to just re-install the OS. It really seemed like a memory problem though. Just don't really have the time for this right now.

Thanks for your help velocity
 
I see you've gotten a web browser to run, dan! (Unless you're on your iDevice or other computer etc.)

Remember to backup most of your things.

Click to expand...

Install takes 1 hour. You can keep all your apps, documents, and user settings.
