Photoshop won't boot up on Creative Suite 3 on my G4

Question

Hi
The nearest topic I saw to this in the forum was "Photoshop hanging", but it didn't answer my question and your guys are technical, so I apologise for my basic knowledge.
I bought Creative Suite 3 less than a year ago, so I guess I am still guarenteed for technical support over the phone? I live in UK and didn't see a free phone no. for us.
So I'll bother u guys in the meantime if ok - My photoshop just doesn't boot up. It was working fine as was all my products on CS3, then suddenly doesn't work. I've tried uninstalling and reinstalling.
My mac is a G4 and I added extra memory when I first bought CS3.
Regards,
Colin

Allen,
Thanks for your effort, but this still doesn't help me. Like i said originally: " My photoshop just doesn't boot up. It was working fine as was all my products on CS3, then suddenly doesn't work." This means that I can't even get preferences/ performance etc.
Buko,
Sorry I did add memory: 1GB in addition to original 512mB. CS3 worked fine for some time then PS started playing up ie not booting up. Under applications, it gives this version: 10.0.1 (10.0.1x20071012 [20071012.r.1644 2007/10/12:09:30:00 cutoff; r branch]) which seems quite unusal?
These are the details of the memory:

DIMM1/J7:
