[QUOTE="pigoo3, post: 1134785, member: 56379"] This may or may not solve the problem...but the first thing I would do is try replacing the PRAM battery. If your iMac is an "iMac 4,1"...it's one of the very 1st Intel iMacs with the white plastic housing. If you're not familiar...you need to open up the iMac to replace the PRAM battery...not a very easy process on these iMacs!!!:( Here's the procedure: [url=http://www.ifixit.com/Guide/Repair/Installing-iMac-Intel-17-Inch-Logic-Board/895/1]Installing iMac Intel 17" Logic Board - iFixit[/url] The photo in step #18 shows the PRAM battery. You don't need to follow the whole procedure...since it's actually the procedure for replacing the logic board. This was simply the closest procedure available to show how to get top the PRAM battery. So you shouldn't have to go past step 18. You need a CR-2032 battery...just like this: [img]http://eshop.macsales.com/images/_inventory_/110x110/NWTCR2032.jpg[/img] ...available almost anywhere. If the new PRAM battery doesn't solve things...then we can go from there. HTH, - Nick [/QUOTE]
