IMac G5 keeps on fading then restart again
My problem occurred recently with my iMac G5 which up to now has not had a single setback for 5years and it has served me well. The dilemma is, the computer erratically dies momentarily and fades out to black and restarts again after a few seconds returning to the image and place it had just left when I try looking at images in Adobe Bridge and/or Photoshop and want to carry out slight adjustments.
I have plenty of hard drive space and have allocated Random-access memory (RAM) as advised in Photoshop preferences. What is likely the problem? The Mac is running on Mac OS X version 10.4.11 with a 2.1GHz processor and 1.5 GB ram.
My computer knowledge is scanty and I’d like to have suggestions on what might be the cause of all these. Is this an indication of something more severe? I really have no money for a new Mac. Please help me out.
