lar_nar57 Posted November 17, 2007 Share Posted November 17, 2007 I recently upgraded my Mac G3 450mhz OS-X memory to 1GB (4/256 mb) 18GB SCSI OS/boot fixed disk ------- 120 GB ATA IDE slave fixed disk All I get at post is a grey screen with the Mac Icon which flashes back and forth with a question mark folder Icon. Machine will not boot to CD or Fixed Disk. Worked fine before memory upgrade. Troubleshooting steps taken so far: CMD-Option-P-R ---- no results ---- no boot to hard disk or CD CMD-Option-P ---- no results --- no boot to hard disk or CD CMD-Option-F --- no response to access to CMOS --- no boot to hard disk or CD "C" key on post/bootup ----- no results ---no boot to hard disk or CD Programing button ---- executed command --- "mac-boot" ---- no results --- no boot to hard disk or CD Signed ---- frustrated hardware guy. lar_mar57 Email Link to comment https://www.insanelymac.com/forum/topic/71926-hardware-upgrade-troubles/ Share on other sites More sharing options...
