Hi All
Anyone have any ideas what may be causing the following issues in an iMac DV SE and how to rectify them:

"3 strikes" before powering up, I have to reset it twice before the screen will come on and the chime happens

Surging/flickering in speakers, they buzz and make a flickering sound even when the iMac is shut down and head phone in

Visible screen refresh, the centre of the screen is clear but the edges seem to roll and quake. I think that has something to do with the kinks in the black cable that surround the CRT for some magnetic thing???

crashing in fullscreen mode for most Open GL games especially games that launch movies

It is using an older IDE HD taken from a beige G3 and I received it dismantled so more than likely there's static discharge damage

extra info: running 128MB RAM, OS 9.2, 4.2 GB HD rather than 13GB

Anyone else had extreme issues like this or know what's the best option apart from part harvesting or trash? Is there hope?

Regards Christian
