My iMac turns on to either beeping, a white screen or both.
Hi, I was given an iMac 24” 2007 A1225, which I’m told functioned fine until something happened with the hard drive not being found or something.
I acquired a different hard drive, a 1TB, but upon testing it I get the same problem, a repeating three long beeps sequence and nothing more.
I tried checking the RAM and if I remove one, the left one, the screen comes on, but then I get the beeping again. If I put the right card in the left slot I get a white screen, with no beeping, but nothing else until after a while, when a file icon with ‘?’ inside it appears. If I swap both cards then I get both beeping and white screen again. I obviously have opened it to swap the hard drive.
I didn’t see anything visually wrong, now I’m wondering if I shouldn’t try the old HD with cards swapped. The newer HD was in a different iMac so it shouldn’t be the problem but, idk, I got it from someone else in my building, so I don’t know for sure.
If you can tell me what is the problem without me needing to open it again to swap back the HDs, that would be wonderful as I’m a little shaky handed and want to reduce the possibility of causing harm. Thanks.
