problem with color settings in Photoshop CS2

After installing the Adobe CS2 I was getting message advicing that the colour profile for my monitor (IBM ThinkVision L200p) is corrupted. If I ignored the profile all was working fine. Today I have reinstalled drivers for my monitor but this message did not want to go away. I experimented with the color settings and now I can not have the colors right. When I am creating new document with white background only in RGB mode it opens as white, all the other modes are giving me light yellow background. In all modes there is no white in color swatches, white turns to yellow. When I am opening black and white images they have yellow background. How I can fix it ? Do I have to reinstall my software, reset those settings or there is some other way to fix my problem. The same settings in Illustrators are giving me the right colors, only in Photoshop I am having problems.

Thanks for help.

Photoshop is more picky about the display profile being usable.

In this case, you have a defective display profile and you need to replace it.
