Recieving a message 'Photoshop CS5 has been stoped Working'

one of those screenshots shows 1gb of memory.  is that correct?

Also check you reliability log to see if you can find out what is failing in Photoshop. Also a 32 bit 1GB system is not the best machine to run Photoshop on...

Double click on more then one of the Photoshop.exe stopped working entries to see the details like I showed. The details may show what is failing. Like mine showed it was in Photoshop ScripUIflex module.  Used by scripts with Dialogs a would guess.  Check several of yours. See if its always the same failure. The one you show is in widows ntdll.dll part of windows. On my system there are two ntdll.dll one 32bit version and one 64bit version. What were you trying to do at the time of failure

Also doing a google search on faulting module ntdll.dll returned 59,200 hits I would not know which to begin with.

The onOne message means that your onOne plugins are messed up -- disable them, and check with onOne for updates.

They are probably also the cause of your crashes.

Plug-ins get installes somwhere in CS5 Photoshop cs5 Plug-in tree or the additional tree you add into you Photoshop CS5 preferences. Look in your "C:\Program Files\Adobe\Adobe Photoshop CS5\Plug-ins\" tree for onOne Plug-ins they may have their own folder.   Remove or rename them to "name.8bf.disabled" then start Photoshop and test..
