Safari will not allow me to visit any websites on 2005 PowerMac G5, OS 10.4.11

Hi. Long story short I fired up my old (and working perfectly when I put it away) 2005 PowerMac G5.

I never had this problem before, and everything else is working fine on the computer, just as when I put it away, but it now does a couple things it never used to do.

• Literally every website I try to go to (except Apple's) it gives me a error saying something like it can not connect because it it can not make sure the server is secure. I mean I literally can go nowhere so far except google search and Apple. And the google page looks weird. Like old or something. It doesn't look like what I am used to on my other newer computer.

All network settings are as they were and working fine and I am hardwired Ethernet.

• The other odd issue is even though I have time set automatically and I'm hardwired ethernet, every time I turn the computer on now after turning it off (and unplugging it from the wall too) it tells me my time is set to prior to 2001 and this may cause issues, lol. Yet when I look at the date and time, its spot on correct and current to today. When I close that warning, it never comes back (even after reset), until after I turn it off and unplug it from the wall, then later turn it back on. Does this point to my internal battery went bad ? Or is this normal if the computer is unplugged from wall ? I do not remember it doing this when it was brand new, I felt I remember it holding the time no matter what.

Thanks for any help - Much appreciated
