    This is a G5 2.5Ghz Quad. OS X 10.5.6. 8GB RAM. I get the boot sound, then a grey screen. That is all. Then the fans start blowing real loud until I turn it off.

    First of all your MacBook Pro is probably hot enough as it is?? The only solution I have heard of is that you can overclock the video card in Windoz in BootCamp wth the ATI tool, load it into the video card and when you are back in OS X it will be overclocked. I don`t think you can overclock the CPU on a MacBook Pro because it uses an EFI bios and I have not seen any overclockers software support for that.

    How in the world can some of you know all this? I checked the apple support article about the LED bank. I am sure the RAM pair I am using is good. When I start the machine the light nr. 2 lights red, and the article says "Contact Apple or an Apple Authorized Service Provider". David, there was no moisture under the CPUs. So this means the logic board must be replaced?

    Thanks for all advice. I tried to replace the clock battery, used the CUDA button, removed all but 1 RAM module. No luck. Now there is not even a grey screen. Strange because I have 2 G5s that are exactly the same and both are sick now in the same way.

  • Answer to: How do I make my Hard drive bootable? Nov 10 @ 6:07 AM

    Another good article I found on installing on a USB flash drive. Which would be much the same as a Firewire drive. I expect you want a minimal system? http://blog.bradbergeron.com/2006/11/how...-install-and-boot-os-x-on-a-flash-drive/

  • Answer to: How do I prevent my guitar's input jack from loosening? Nov 10 @ 6:04 AM

    Here is what I did. I took out the jack and stuffed (really hard) steel wool, the stuff you clean pots with, into the screw holes. Then the screws fastened real tight. Much better than glueing which is not very reversible!

  • Answer to: Battery life less than expected Nov 10 @ 6:01 AM

    Just my advice since I have a 16GB 2nd gen. iPhone. When I upgraded to software v.3 it did not last even a day. I found the clue is to turn off all "push" settings in email. Set everything to "manual" and do it everywhere, also in the submenus. That gave me back my battery life at least.

  • Answer to: How do I make my Hard drive bootable? Nov 10 @ 5:56 AM

    Now this is important. You don´t write what Mac you want to boot from the drive. I.ex. a PowerPC formatet boot drive will not boot an Intel Mac. So when you format the drive in Disk Utiliy choose "Partition" and how many partitions you want (usually one volume). Then click on "Options" and choose "GUID-partition table" to boot an Intel Mac and "Apple-partition table" to boot a PowerPC Mac. With an Intel Mac you can also boot from external USB (only Firewire on PowerPC). This is handy and I have a USB stick that is loaded with utilities that I have saved a lot of Intel Macs with. Here is a tip on creating a minimal boot disk with your own tools: http://www.techarena.in/guide/9476-create-bootable-mac-os-x-dvd-clone-x3.htm and besides that you could google "create os x boot disk".

  • Answer to: Defragging Mac OS X hard drive Nov 7 @ 5:21 AM

    The question is, does OS X need a defragmenter. Mac OS9 did. I would say it can help if you have many large files (video etc.) or you are running low on disk space. For a starter Cocktail does a good work at maintenance (http://www.maintain.se/cocktail/index.ph...) although ti does not do defrag. You would need something like iDefrag (http://www.coriolis-systems.com/iDefrag.php). I have tried iDefrag with good experience. But did I notice anything else than prettier defragement graphic bars? Not really, or someone else may have different experience. Take a read here about defragement and OS X: http://reviews.cnet.com/8301-13727_7-10328197-263.html

  • PowerBook 17" says I have no mouse or keyboard! Nov 4 @ 3:39 PM

    Hi,

    I changed the broken LCD of my 1,67Ghz 17" PowerBook. I was assembling the flat ribbon cable from the keyboard through the logic and close to the RAM I was just testing without the battery (charger plugged in). Suddenly there was a small spark and a trail of smoke (!!) coming from the connector where the flat ribbon cable goes in. I can see it has a smal burn mark. Now the PowerBook works fine, boots but complains that it does not have a mouse or keyboard. Is there any way I can repair that connector or do I have to buy a new logic board?
