JAVA 10.3.9 update

Yes, I have a brand new Dell multi-platform monitor to replace my old Apple Studio Display that started going out--I thought. This new display worked perfectly about a week and a half and I rebooted the computer only to find that the new display looked as bad as the one we just replaced. After doing a lot of checking, repairing boot blocks, etc., I think it is a software corruption of some kind, so I've already updated the Radeon 9000 pro driver, replaced the latest system update, and zapped the Pram and everything I could think of. the display works fine when the computer is started with an external system CD. It's only two weeks old. It doesn't appear to be a type of video card problem, so I'm looking at possible software issues like Java, Flash, etc. Any suggestions? I don't play games. I use my graphic/layout software on my older Mac G4 mirror doors because I can't afford to buy new stuff for my Macbook laptop. When I start up or reboot, the display is beautiful for about 10 seconds and then zap--it loses high definition and gets weird colors.

Thanks for your reply and advice. I went to the console (never done this before) and saw some error messages. Under console.log, it referred to Firefox with some unknown text and then said "flash player.plugincos(kern) invalid argument. and then something like "media disappeared" I'm having some difficulty reading the small text with the monitor's erratic display, but I went to the system log and starting at what I recognized as monitor and found:

Kernel: Adaptec warning: resetting SCSI Bus

Kernel: BSDroot:diskUS9, major 14 minor, 9

Apple CPU couldn't parse platform function

Jettosing kernel linker

Returning false early, connector or machine incorrect

Then many lines that seemed ok, at least no error or warnings and then...
