Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Hi and thanks for that very detailed reply! I surely appreciate it.
(BTW, I tried the Macbook SMC Update v. 1.1 that some have suggested but her computer said it was already there.)
There's a lot to digest here, so I'm going to have to take it in bit by bit. Does seem like this is a software thing, and I have not yet upgraded her machine from Leopard to Snow Leopard, which came on a disk with the machine in Aug. '09, but I never installed -- it's been fine. She HAS, however run through a number of DC mag. tips with her 60W adapter -- maybe they're crap and provide less than 60W and burn out.
I did a disk verify (not disk repair) using the disk utility on her machine (not from the install disk yet), and all it said was disk appears OK. Then I did a permissions verify, and it said it found a lot that it didn't expect (as I recall -- trying to get a lot done today), but didn't suggest any repair. And I didn't ask it to repair them. Don't know how long that will take and she needs it for homework tonight.
I guess using disk utility from the original install disk is a bit different? (New, fresh and unadulterated?)
Sounds like I'd better look through all your info carefully before proceeding further. From what you (and others) say, it really does sound like a software thing, which doesn't surprise me at all. It only happened when she was using Safari. Just 2x so far. AND it happened when the magnetic DC attachment was in the process of crapping out (as so many others have done!) and possibly confusing the **** out of the system (DC in/DC not it/etc., etc. every second or so. She always runs on DC power and the system always sees it properly.)
I gave her a new adapter and all still seems well. Actually, the machine seems to be running cooler now. I gave her an 85W rather than the 60W her 13" came with (since it will only draw what it needs -- but if the "60W" is actually giving too little, that's a strain). I've always felt the 60W sources just barelyprovide what the machine needs.
So I'll do the permissions repair as you suggest, then when she's on spring break and I can take the damned thing for a full day or more, do another full backup and install Snow Leopard.
Will keep you informed. Thanks so much!!
