Late 2007 iMac 20" Freezes completely random.

[deviant]

So I’m a Little confused about this whole situation, I have a 2007 iMac 7,1 and it does all the things described since the 2011 posts it locks up but everything in the background is still going music ect, what do I need to do to fix this issue because there are so many contradicting opinions on how to fix it, I’m on 10.6.8 I know it’s a bit old but haven’t upgraded RAM so not going to go to higher os, CAN SOMEONE PLEASE TELL ME WHAT TO DO TO FIX IT, I heard about swapping kexts from 10.6.3 but that was in like 2012 so I’m lost could some plz help me...........

i have 4gb ram and an SSD in it so El Capitan works great on it. 10.6 is snow leo, right? i mean, i wouldn't say it's useless nowadays but i can't imagine how much software doesn't work on snow leo anymore. if you still want to keep your 10 years old imac i suggest to put a SSD in it and upgrade the ram. i haven't had any issues in El Cap with it, but my iMac basically became a TV in my bedroom..
