My Safari doesn't format correctly
I'm running Safari 5.1.5 (6534.55.3) on a Mac mini with 1 GB RAM- older November 2007 model that has 1GB on it now and only goes up to 2GB. It had Leopard on it (it was my fathers) and appears to have lost it's ability to format correctly (style sheet missing kinda thing). I upgraded it to Snow Leopard in the hope that the upgrade would fix it, but it hasn't. It basically just shows text in bullets down the screen, but no graphics, no formatting. I tried this on several sites of course - apple.com, cnn.com, etc but no luck.
Can anyone help me with an easy fix to this? I've tried resetting Safari, emptying cache, etc.
Thanks!
Mac mini, Mac OS X (10.5.8)
