G4 Quicksilver won't power up
I've got a friend with a G4 733Mhz Quicksilver Power Mac.
She had a stick of 128Mb and 256Mb RAM in it and fitted another stick of 512Mb RAM.
When she powered up, OS X couldn't recognise the new 512Mb.
She turned it off, took out the new stick and turned it on again.
It now only whirrs for about 5 seconds before it powers down.
So far she's tried:
• pressing the PMU button
• taking out the battery, leaving it, putting it back and pressing the PMU button
Every time it just lasts 5 seconds before turning off.
I'm going to try and fix it in a few hours, but does anyone have any suggestions?

Make sure she didn't accidently dislodge the other RAM, which would most likely cause these issues.
If that fails, try one by one at a time each RAM stick, cycle them through each slot etc, something may have been damaged.
Also check the graphics card and see if it's in properly (if not screwed in tight enough slamming the case shut can dislodge it).

I'd try resetting the PRAM as well. On boot(immediately after you press the power button, about the same time it chimes, press command, alt, P, and R at the same time until it chimes again.
