Imac 2008? 10.6.8

Postby poundu1 » Wed Jan 14, 2015 10:37 am

I have an Imac running snow leopard 10.6.8 that has 3 Gigs of RAMM 1 1GB and 1 2GB. It worked fine for 6 months then a month ago I started to get screen freezes where the mouse would move, but nothing would respond, and I would have to power off reboot. For some reason that has stopped and I started getting the Mouse pointer freezing but the kb would work. So I press apple key + F5 and get voice over and 5 or so seconds later the mouse will start working again. this would happen once or twice a day. Today it has happened every 10 min or so. No updates or new software has been installed I have always used a USB Logitech pc KB and 2 button wheeled USB pc mouse, as well as Google Chrome. I ran ClamX once a month and has always come up clean. Could this be a RAMM stick degrading?
thanks

I'd say ram or hard drive. don't know much about macs... I guess this is a laptop? is there an hdd diagnostic built into the bios or OS you can run? I've seen them do this stuff at an apple store.
you could also try pulling a stick of ram at a time to see if the problem continues. but ram is usually pretty hearty, so I'd guess hdd first.

could also be a heat problem, are all the fans running, have you cleaned the ports to be free of dust?

No its an Imac "20, not a laptop. I have not seen any stock diagnostic apps for hardware I will research. When I originally got this Imac I thought that it may have had cooling issues because it seemed to be running hot however it was summer I had the system in a congested corner without room for air to circulate, so I moved it and it has been fine. I hear a what I assume was a HDD fan whirring, but the speed never changes and have had no issues until now. I tuned the system off and let it completely cool down. when I turned it back on the mouse pointer would move for a couple of seconds and then it would freeze. The optical mouses light turns off. I can unplug the mouses USB cable and plug it back in and iy would work for a couple of seconds. Its been 15 minutes and its no longer freezing.... go figure. scratch that it just froze again

Some tech info on that iMac.. http://support.apple.com/kb/SP616
Main memory is SO-DIMMs, either a single or a pair of 1 GB or 2 GB 1066MHz DDR3. Up to 8 GB total.
Having 3 GB is a mixed amount, but should work in single-channel setup. Dual-channel setup requires both channels to have a matched pair of modules for stable operation.
But ensure both modules are exactly the same as to timings. If not, then the slower module must be the first detected, to set the proper speed for both modules. If the faster module is first detected, it can overclock the slower module.. and lead to system freezes.
F@H.. to solve mankind's maladies.. in our lifetimes!

I will get a matching pair then and see if that resolves. For now here is some kernal logs that mention the mouse: (about %20)

The mouse is just waking up the network card.
The other thing I see is Google Chrome slowly chewing up memory, update that thing first...

And run this:

Something else that needs a check.. the mouse cable. If in use for more than a year, with a lot of flexing, the conductors can separate.. giving intermittent response! Usually happens right at the mouse. Doesn't matter the mouse type, brand, or quality.. that is a weak point in the cable. Have had to twice "cut its tail" and splice back into good wire connections with one. I keep another at the ready, in case.

I will get a new wireless mouse to replace this USB mouse, and matching memory modules this weekend.
I see a disk utility app that doesn't appear to have diagnostic capabilities, just restore partition from what I can tell. I will research more.
There are 3 USB ports which I use all 1 KB 1 mouse 1 iphone dock. I unplugged the iphone dock and still have same issues.
