Hi everyone, I bought a brand new iMac and its driving me mad, since I got it (Im all new to macs) Im finding that when I want to load a page on safari the blue line goes along a little then stops dead then doesn't go any further, then I get a rotating rainbow circle that just keeps rotating, I initially thought it had something to do with my broadband, but Ive now had 8 line engineers out and broadband engineers put a new hub in and everything is working perfect so it must be my new iMac how can I fix this as I am now on the verge of smashing this damn computer and I am wishing I had just bought a new windows touch screen this has been such a hassle to me its just not worth the cash I paid for it to have so many problems!!!!
