Strange dates

Hi

I run an imac. The one just before they built in the little camera.

My machine was running weirdly a few weeks ago. It kind of ran a greyish tone over the whole screen with a warning. Same sort of symptoms that caused me to have to get a new mother board on it a couple of years ago.

Anyway, I ran YASU over it, and haven't had those problems since. However, I noticed that some files (about half) now carry dates in the 1970's!

Should I be concerned about this. And is there anything I can do to fix the problem?

Thanks for your help.

Well, your pram battery could be dead, which would expalin the weird dates, because your time was reset, to get it back go to System Preferences, go into Date & Time and if your connected to the internet, click the box next to Set Time and Date Automatically, if your no connected just change the date manually and exit System Preferences. Have you disconnected your iMac or lost power to it?
 
If the screen turned grayish sort-of and showed a picture of the power button, that would be a kernel panic. That is, a system crash. System crashes are usually related to a problem in hardware. The first thing I'd investigate is your RAM. Maybe a defective RAM module.

But that's not the only possibility. I hope it's not a defective motherboard.

Good luck.

Just one notice why the 1970s: OS X is UNIX and in UNIX time is calculated as seconds from 1.1.1970. So if time is reset, it will start from zero, i.e. 1.1.1970 00:00 (in London).
