Kernel Panic Help

[ChrisAbalos]

Hello everyone,
For some reason i keep getting the following kernel panic. It seems to be happening on a daily basis now. Sometimes my computer wont wake up, sometimes i get the restart screen, and sometimes it comes up as white letters on a black background over my frozen desktop...i have no clue what might be the problem...Any ideas?

If you've added RAM, take it out and see if the problems come back. If you haven't added any, I would try taking out the standard RAM and putting in known good RAM and see what happens. A bad stick of RAM is the most common culprit to consistent kernel panics.

 

[ChrisAbalos]

There is a Gig stick of ram in it that i put in about 6 months ago. This is the first time ive ever had problems. Does RAM just randomly go bad sometimes?

Thanks

Yeah, sometimes it does. Take it out and see if your kernel panics keep happening.

 

[mklos]

Yeah I had the 256MB DDR DIMM in my imac G5 when I had it go bad, which was the RAM that came with it and it kernel panic'd almost everyday until one day I took it out and it never did it again. I had that iMac from April until August and it did it like the last week of July, so problems with RAM can happen at any time.

Since a week I have the same kernal panic, and my thrid party ram is installed over a year ago. Maybe something in the OS or the first os X virus?!?!

The 10.4.3 update seems to have been particularly hard on hardware, acting as a trigger for slightly bad RAM (unnoticeable) to suddenly go completely bad.

It seems hardware has been pretty well covered. One software question: Are you running any torrent programs?

Both BitTorrent, Azureuz and other torrent clients have been known/reported to cause Kernel Panics, especially just after System upgrades.

Well like we said, RAM can go at any time. It can be fine today, and crap tomorrow. So it really doesn't matter when you installed the RAM. Mac OS X.4.3 seems to be showing the hardware problems.
