Power Computing's troubleshooting guide declares that if you have: 1. Reset CUDA 2. Removed all third party ram and the L2 cache. 3. Reseated the CPU card. 4. Reseated the ROM (I believe the ROM is soldered on the logic board on that machine, so this may be academic) and you still have the Power On/No Chime/No Video problem, then a defective CPU or defective ROM on the logic board is the probable case. Here are a few other things worth trying (if you haven't tried them already): 1. Try to boot up from a bootable CD (Power Computing said: "If the machine won't boot from the Power CD with all externals disconnected you have a probable hardware issue.") 2. Pull the L2 cache and try to start (with the cache removed) 3. Disconnect all externals (I'm sure you've tried this already) and try to start 4. Disconnect all ADB devices (keyboard, mouse) and try to start 5. Locate and disconnect the audio cable inside the box and try to start 6. Boot with extensions turned off (I'm getting desperate now) 7. Remove/disconnect all third-party devices (CD-ROM, hard drive, etc.) and try to start (before long, you'll have the machine entirely disassembled!) Good luck. I know how frustrating this can be. -- Power Computing is sponsored by <http://lowendmac.com/> and... 123Inkjets.com <http://lowendmac.com/ad/123inkjets.html> Support Low End Mac <http://lowendmac.com/lists/support.html> Power Computing list info: <http://lowendmac.com/power/list.html> Send list messages to: <mailto:[EMAIL PROTECTED]> To unsubscribe, email: <mailto:[EMAIL PROTECTED]> For digest mode, email: <mailto:[EMAIL PROTECTED]> Subscription questions: <mailto:[EMAIL PROTECTED]> List archive: <http://www.mail-archive.com/powercomputing%40mail.maclaunch.com/> Using a Macintosh?
