[QUOTE="penta, post: 1265507, member: 207354"] i downloaded Onyx and was ready to run it, but there's a warning about possible data loss. i can't risk that at the moment (client data on my computer), so i decided to reset the parameter RAM. after the reset, the problem came back. then after another restart - i've had 48 hours without the problem occurring again. if it comes back, i'll post again. but if i don't, then that means the problem is solved. if anyone has a similar problem, here is the instructions on resetting the parameter RAM: 1) * Reboot the Mac. Immediately after you hear the startup tone, hold the shift key. You can release the shift after you see the grey Apple Icon. a) This will force the Macintosh to startup in Safe Mode. Unlike Windows, it will also force the computer to scan and repair the file directories. 2) * After Safe Boot, restart the Mac and this time hold Command, Option, P, and R. Release the keys after a second startup tone. a) This will reset the Parameter RAM (PRAM) The PRAM holds information about mouse settings, application fonts, monitor depth, virtual memory, and other things. Sometimes the PRAM gets corrupt and makes your Mac unstable. [/QUOTE]
