Customer Question

iMac 4.1 running OS 10.6.8. Once had APC Powerchute UPS installed, but removed. On boot up get error message:"an APC UPS not detected". Under System profiler "power" states "no hardware", but under "startup items" "comapcpcpestart" is listed and "power chute enabled". How do I deselect item from boot? Occasionally makes beeping/shuttering sound like if you hold down a key on keyboard.

Go to Macintish HD / Users / yourusername / Library / Startupitems and see if the file is there. Also check Macintosh HD / Library. If the file is there drag it to the trash and restart. Let me know it may be in another location.

Thank you. we are half way there. The file was removed, but problem with something triggering staccato sound like pressing continuosly on keyboard. the #8 key is continuously activated, typing 8 into the spotlight search window. Also, when placing mouse over action windows (file, edit, view, etc) the executable(new window, file open, new tab, etc) flickers. Do I need to do a restore?
