I Have a very strange problem with XP pro SP1 and a 2gig Celeron. I can not run Photoshop 7 without getting runtime C++ errors. I've reinstalled DirectX 8.1, Tried several different video cards and Drivers. I even installed a new hard drive with only Windows XP Pro SP1 and Photoshop 7. Nothing works. I can run 3D programs such as Poser 5, Vue D"Esprit 4, and Bryce with no problems including rendering. But I can't get Photoshop to work. I have the same copy of Photoshop running on three other computers with no problem. It also ran on this Computer until I went from a 1gig Celeron to a P4 2gig Celeron. Both chips are on ECS motherboards with VIA chipsets. The Change over was really no problem except for Photoshop. Anyone have any idea's? I had no luck even with a new hard drive and a clean install. It really seems like it would have to be a hardware issue, but everything else works fine so I'm hoping there's a software solution.
