serious colour problem!

Hi, I have been having a serious colour problem for the last 6 weeks and tried everything to fix it: Some images appear to be highly saturated when opened in Photoshop, Preview or iPhoto. When sent to another computer the images are fine. I have tried all the following but to no avail:

Coloursync first aid
A different monitor
installing 10.4 and then reinstalling 10.4
disk utility (repairing permissions and drives)
uninstalling photoshop and trashing preferences

Momentarily, after reinstalling Tiger, the problem seemed to fix itself, but then when I opened iphoto other images had suddenly become saturated. It seems to affect some images and not others. Also I opened images in photoshop and tried to save them in different formats(from Tiff to Jpg etc.): Images that had been fine had suddenly become saturated. I updated all the necessary software to bring me up to 10.4.9 but the problem continues. Can anbody out there help?????

POWERMAC G5, Mac OS X (10.4)

Have you run the OSX monitor calibration (System prefrences --> Monitors ---> Color tab ---> calibrate)? I know that is kinda basic but ya never know. If that fails then the only other think I could suggest is that you have a faulty graphics adapter. I am assuming that when you say highly saturated you mean that the colors are almost bleeding on screen?

You won't believe how many times I calibrated this thing. That was the first thing I did. The wierd thing is that after reinstalling Tiger, (I think the 3rd time!) it worked for about 20 mins. I then connected to internet via safari and suddenly my screen when out of focus and then....saturation problem came back. Another odd thing. Images created or imported prior to a certain date are fine(no saturation..or bleeding).

I have just thrown away Photoshop and am seriously thinking that the next thing out of the window is either me or the G5

Thats kind of my point. There is the possibility that something is staying in the system that is causing the problem, even though you are doing the archive and install (especially if you are keeping usersettings intact). You might want to back up and try doing a full wipe and reload of OSX.

Just to be sure, you are saying the colors are oversaturated in all programs, including the web?

No, it's not the contrast slider in universal access. It's definately not something obvious. Yes it occurs on some images on the net. But, as I said before it affects only some images and not others. There seems to be nothing special about the images that it chooses to oversaturate/bleed, other than the fact that some of them have been through photoshop, and some of them have been tiffs at one stage or another. But the tiff thing has nothing to do with images on the net so....what's the answer. I founf this yesterday, and it seems as if he's made the diagnostic but not found the answer:
