I turn off my Mac Power 5 and took off the memory modules to find out the exact kind to upgrade. After that, I them put back. Boot up my machine. Power is on, but nothing work. What's the problem ? how to fix it ? Thanks
Did you take care to discharge static electricity from your body before touching the memory modules? If not, you may have damaged them. It's also possible you didn't put them back properly, so check that, but discharge static electricity from your body first. Static electricity can destroy memory modules, that's why they are (or should be) supplied in an anti-static bag when you buy them.
Thanks Bill ! I did discharge the static electricity and put them back correctly.But I
don't know why the machine don't boot at all.Is there anyway to put it back to work?
