Mac Pro resetting PRAM by itself?

My Mac Pro 4,1 2.66 quad seems to be resetting it's PRAM on it's own lately. Recently I turned it on and most of my settings had been set back to default (Mouse, etc...) And it seems that all the cookies were removed from my browsers. Is this possible or do I have computer gremlins? It's running the latest version of OS X 10.7

PRAM/NVRAM has nothing to do with your mouse or cookies in your browser.

Hmm perhaps I was mistaken, I thought it contained mouse settings among others. Maybe the SMC was reset?

The SMC doesn't have anything to do with your mouse or cookies, either, and your computer cannot reset NVRAM or SMC by itself.

I'm aware, hence my confusion over why my settings and cookies are disappearing.

Which browser and version are you using?
Have you tried resetting it, clearing your cache and cookies?
What browser add-ons, plug-ins or extensions are you using?
Can you be more specific about what mouse settings have changed?
What kind of mouse do you have?
Are you using any mouse configuration software?

And don't forget we have just been updated to a new version of Safari... isn't it a little likely that Safari updates might clear cache and cookies?

I'm only using Chrome and Firefox. Both browsers lost cookies.

I use Firefox and Chrome, both the latest versions for Mac (I'm not near my MP so I can't give exact versions). Only extensions I'm using are the StumbleUpon bar and PDF Viewer for Firefox. Haven't checked Safari because I don't use it and don't have any bookmarks or cookies in that browser.

I'm using a Magic Mouse. Mouse settings went completely back to default, i.e. Tracking speed, scrolling direction, multi-touch gestures, etc... This all occurred on a fresh boot, I typically shut my MP down at night and during the days that I'm not working at home.

Did it happen only once, or does it happen every time you reboot?

Just the once so far, I've let it sleep since and it hasn't recurred.

I would try restarting again. If it doesn't happen again, I would write it off to a fluke and wouldn't worry about it. If it does happen again, it merits more troubleshooting.

Sounds good. I haven't shut it down because I didn't want it to happen again, but I'll restart it later tonight and see what happens.

Just a quick update, I've restarted it a few times since yesterday and it hasn't happened again. Must have just been a fluke.

Thanks for the update. Chances are very good that you won't see it again.
