I have an old Sawtooth G4, 500GHz AGP graphics, 1 gig of SDRAM, a scssi drive, running Mac OS 10.3.9, hooked up to an external Maxtor USB drive and a FireWire LaCie, with a 17" Studio display.<br><br>When I click on "shutdown" the icons disappear, the monitor dims, the whirling bars rotate, the screen goes dark, and the CPU does not shut down.<br>
<br>I have to push the power button on the CPU itself to get it to shut down.<br><br>This has happened occasionally in the past, but is now happening almost constantly.<br><br>I have run Disk Utility, verified and repaired, thinking something had been corrupted, and also ran Tech Tool Express, all report everything is OK, but still, this problem.<br>
<br>Any suggestions as to how to rectify this would be appreciated.<br><br>I use this old desktop a lot, like the way it is set up, like OS 10.3.9 on it, and would hate to have it pooch out.<br><br>Thank you in advance!<br>
