Hi Everyone.. Would appreciate some thoughts, feedback and HOPEFULLY a solution to my little iMac issue. For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired, or its just being a little **** . So, often it wakes up normally and functions fine... well, not really... It is seemingly VERY slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think... so It's just a lot slower in general than before. Has anyone else experienced this issue or heard of this before?
