Q: 30' cinema screen flashes and off continuously.

Since upgrading RAM ( over the w/e) in 2008 Mac Pro the 30" cinema screen has flashed (on/off) continuously, it stopped only if I held my finger near the on off button on the side of the screen. Also connected is a 23" screen (unaffected). I have checked all power sources etc - all seem OK, I have also set the screen button to 'do nothing'.

Upon swapping inputs for both the screens the 30"cinema screen although not flashing now doesn't seem to switch off properly, Also when switching the equipment on again the desktop and screensaver as chosen by me have reset to an Apple default. All very mystifying and frustrating. Any advice and suggestions will be appreciated.
