Hi guys, please can anyone help? I am new to this forum so I'm not sure I have posted in the right place... here goes...

Whilst editing images in photoshop cs3 (using power mac g5), random horizontal lines are appearing on images. Usually just one or two and the only way to get rid of them is to edited/erase them out.... They are appearing at random times and places on an image.

I have tried saving and opening image on another mac and it still shows up... help?

Would be very grateful for any ideas on this...

That sounds a lot like bad RAM or a bad CPU (my old G4 laptop developed that problem shortly before it stopped working).

If they disappeared when zooming, then that would be a problem with the video card.

Thanks Chris,
the lines are still there when zooming in or out..
is there any more tests I can do to narrow down the problem?
I am not so good with all the technical terms...sorry! If it is bad RAM, what can be done to sort it?
I appreciate your feedback thanks!

Also I have just started getting problems with the mac itself.
The screen drops down grey and tells me I need to restart it. Could this all be linked? Thanks.

Yes, that is linked -- and again a likely sign of bad RAM or a bad CPU.

Bad RAM you'd have to swap for other RAM to test (software based testers are useless, and hardware based testers are rare and expensive).

A bad CPU is much harder to test -- Apple used to have the diagnostic software to test G5 CPUs, but would probably laugh at a G5 now.

If replacing the RAM doesn't work, then you probably need to consider replacing the machine. Sorry I don't have better news.

Thanks Chris!

I have done a bit of research and gather I may have the 'grey screen of death'??
Some users have recommended trying a 'repair disk' first. And trying 'Applejack' which is free to download.
I will look into replacing the RAM too. Any recommendations for that?
Thanks again, I appreciate some feed back.

Yes, that is the gray screen of death - aka a kernel panic.

A repair disk would help corrupt OS files, but the artifacts sound a lot more like bad RAM or CPU.

Without knowing what other machines you have available (to swap RAM with), or how much RAM you have installed (so you could pull some and use others) -- I don't know what to recommend.
