Q: IOS El Capitan - Computer freezes
I have a 2007 iMac working on OS X El Capitan and my computer crashes all the time.
I was checking all the discussions and found something but it was for IOS Mountain Lion.
Does anybody has the same problem?
Can anyone help me please?
iMac, OS X El Capitan (10.11.6)

It could be a GPU problem. Do you have an Apple Store nearby where you can have it checked out? If so, make a Genius Bar appointment.
I don't know of any third-party software that would cause the video to freeze, so I don't think it would be something you have installed.
If it happens often enough, you could try booting into Safe Mode and see if the problem recurs. Try safe mode if your Mac doesn't finish starting up - Apple Support
You can try to rule out third-party software by booting into Safe Mode and testing. It's not particularly fun to work in Safe Mode, so unless it happens frequently enough to detect in several minutes of use (or you can have it sit running a youtube video and check back periodically), then it may not help the diagnosis.
Even then, some things are not functional in Safe Mode, so if the failure mode of the GPU is not active while in Safe Mode, you could get a false sense of the cause.
