| First, welcome to TSG, and sorry for the delay in responding - usually help comes a tad faster than this...  Anyhow, need more info; such as: OS being ran which iMac [including speed, CRT or flatscreen, etc...] what you mean by "jumping" - constant flicker, jumps on occasion, what is happening when it jumps, and so on are you near any external heat and/or electrical sources? w/o knowing this, can just guess that could be a battery, logic board, or some other hardware problem. Holler back w/ some details!  Rob

| YBBA - this is the CRT [cathode ray tube; ie: curved, not flat screen] model, right? If so, recall that this is more like a TV - where such as a 'horizontal control circuit', or the computer's 'logic board' could be amiss. Of course, there are no magnetic fields nearby? Again, did this just start up all of a sudden, w/o any changes to your operating conditions? As to your window, guess that would depend if you live in somewhere near conditions found near the Sahara or if you are in Siberia...

| There is this issue too...  http://www.oliver-kreuzenbeck.de/iMa...lems/iMac.html Seems that there is potential for some bad capacitors in various iMacs... of course, these are the new iMacs, not the older iMac pertaining to this thread. However, could be similar issue. |
