Greetings!
My iMac is acting up, and I hope that someone here may be able to help.
I'd better do a brief timeline of what have happened, as it have evolved a little during the past 24 hrs..
Yesterday:
1. The machine froze solid, while I was online playing a MMORPG game, I rather enjoy.
2. After waiting a wee bit for the machine to snap out of it, I decided to do a hard shut down and reboot.
3. The machine wasnt able to go past the start up chime with black screen. It just went on endlessly. I shut it down and tried again. I repeated this quite a few times. Only change was that sometimes the chime would sound a little muffled compared to other..
4. I let it cool down for an hour. Tried again. Same result.
5. I tried to run the interior hardware test. It wouldn't go past the chiming.
6. Tried the command-s / shift / and installation disc-boot tricks - no result.
7. Took out the RAM and replaced them with the originals. - no result. I tried to boot with a variaty of set ups with the RAM. - no result.
8. Took out the powercord and let it sit for a few hours. Then tried again. It now booted up as normal and just as I sighed of relief the screen went grey - then black - then the machine shut down and the chiming came back.
9. Took out the powercord - it booted in command-s. I then tried to run the fsck, but the screen went black before I could see anything about the system.
Today:
10. Thought I would give it one more go. The machine booted as normal. Then repeated step 8, but didnt shut down. It sounded like it was still running altho those wee processor-sounds were not there. The screen was grey.
11. Shut it down and tried to reboot. Chime -> grey screen -> nothing.
12. Wrote this.
I am at the point now, where I have no clue what to do next other than either try and open the machine to check for "dust" in the physical interior - or hand it over to my local Apple-vendor to let them have a go at it. I dont have AppleCare, as I forgot about it.. (brilliant, i know)
The reoccuring problem is, that the screen goes either grey or black no matter which "trick-of-the-trade" I try to pull on the iMac.. I can -however- boot it after having left the cord out a bit. When it boots up, it loads all the way with programs and everything and is actually fully usable for one minute max. Then the screen goes grey/black.
As i have been searching my brain for anything I might have done wrong to it, I remembered that it have done the chime-repeating a few times before. It chimed two or three times, but then booted up, and I thought nothing more of it. The machine is bought in may last year, so I kinda doubt, that the interior would be able to get so dirty, that this would be the reason (?)
Any ideas on what I could try to do, or thoughts on what might be the problem will be highly appreciated!
Thanks! (and sorry for the wall of text )
