Hello…
My iMac was purchased early 2007 and has worked like a charm ever since. Yesterday, though, I started getting some moderate to severe screen tearing. Today everything seems fine, except for a horizontal line that popped up on this very Firefox window I'm using right now, which disappeared after resizing the window a little bit.
I've run memory tests with Rember and my memory seems to be fine. I'm wondering if it's a video card issue, or a video card *driver* issue.
A factor to consider is that this machine has been known to run non-stop for months. It is my main machine and I use it for all my design work, and I leave it on during the day to access files on it from the studio where I work during the day. So it may be that those extremely long periods without rest have had adverse effects on my hardware…
Anybody who has seen this before and could give me a clue as to what may be causing this, I'll be very grateful.
