iMac G4 700mHz Flat Screen not Reading Internal Memory
Long story short: my G4 15" flat screen iMac suffered hard drive death in January 2008 (6 years old). I opened up the iMac and replaced the faulty hard drive with a compatible one that was 50 Gig (older one was 40 Gig). Put everything back, and sealed it correctly with thermal paste (per online instructions). Also purchased memory upgrade from originally installed 256 mg user access to 512 mg, which would have given me over 700 mg RAM with the internal 128 mg.
Now, for some reason, the iMac does NOT recognize the internal (hard to access) 128 mg, but only the 512 mg, and about 1 of every 5 times the computer is turned on, I get the three short tones and nothing, which means the computer does not have enough RAM to boot (not recognizing the 512 RAM in the user-accesible slot). I have re-seated the 512 Mg RAM chip twice as experimentation, and the computer works fine for a while (until the next shutdown, power-outtage, etc.).
Any thoughts? Should I replace the internal 128 mg chip with a new chip?
