Error code 4MEM/4/40000000:4e59d0c0 after running HD test from disk. Windows grayed out dock too and chunks disappeared from some. What does this mean?
iMac, Mac OS X (10.6.3)
Problem with memory.
Try reseating memory.
As indicated this RAM related, if reseating does not help it can also be:
Failed RAM
Incorrect RAM
If you upgraded the RAM yourself, it may the incorrect RAM. iMacs are extremely sensitive to RAM and need high quality RAM. Most experienced users on these forums only use OWC or Crucial RAM. If you used anything else there is a more than good chance that is what it is.
Thanx for your replies. I have not upgraded RAM or replaced anything inside my iMac. Everything is original.
How does one reseat the RAM?
This Apple document will show you how to access the memory modules in your iMac: iMac: How to remove or install memory - Apple Support
I am still having this problem. Windows disappear or turn gray when clicked on. Sometimes there are chunks of a window missing, or weird colors. Most of the time when I click around in a window it will restore some or all of its contents.
Dominic, did you mean "reset" the memory or "reseat" it? I have to added any memory to the original 4GB.
I have reset the NVRAM (PRAM). Ran Disk Utility, which reported no problems. Also ran MacKeeper and deleted caches, etc. It seems to have helped some, but the problem persists.
Any other Ideas?
I am not sure if MacKeeper is much help, at least not as far as fixing problems. Is Norton Utilities and Disk kWarriors still around and better tools?
For whatever reason, that Mac's memory has failed and needs to be replaced. It's not expensive.
MacKeeper won't help. Neither can Norton Utilities, Disk "Warrior" or any other garbage. They will only cause additional problems that are very expensive to fix, in terms of time, money, frustration, lost data, or all of the above.
I suspect it is the memory that is the problem from what has been said here. Similar to a problem I had years ago.
When I checked "About this Mac" it reported that the two 2GB chips were "OK." Why would it be labeled OK when it is not?
John, would you elaborate on your opinion of Norton and Disk Warrior please? Both worked well for me, at least under OS9.
Thanx, one and all, for your help.
MacKeeper is considered malware around here. Read this user tip and follow the links to the recommended methods for uninstalling MacKeeper: Do not install MacKeeper. It's been reported here to have damaged systems and applications requiring re-installs.
Also as John pointed out anti virus software isn't needed by Mac systems. They just slow things down.
If you haven't repaired disk permissions since upgrading to Yosemite boot into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and repair both the disk and disk permission.

Unfortunately it is impossible to evaluate memory's compliance with specified limits while it remains installed on a system operating within those limits. AHT may even report memory passes its tests only to have that same RAM fail in later use, when some other internal or external parameter changes. If AHT reports a failure though, it's a conclusive indication of failure.

The only possible way for Norton to have worked well under OS 9 would be to leave that Mac unplugged, in its box, on a shelf, and out of sight. Norton's early versions were notorious for corrupting a Mac so badly that erasing it was the only known recovery method.
Disk Warrior may work well to recover data from a disk that you might otherwise throw in the trash, so that you may recover its data as the final act prior to throwing it in the trash.
Nevertheless there is almost nothing about an operating system well over fifteen years old that remains applicable today.
I mentioned Norton & Disk Warrior because I was wondering if they were still around (and worked any better) or if there was anything other than the native Disk Utility (which seems to work just fine).
I have un-installled MacKeeper. Waste of $$!
I will replace both RAM chips and see if that does the trick.
I recently had a power surge here during a storm, power of and then right back on. Maybe that affected the RAM.
Thanx for the help everyone!
John & Old Toad- I tried to click on "this helped me" and "this solved the problem" but after 2 clicks the page would not accept any more.
