[QUOTE="pigoo3, post: 1799873, member: 56379"] Thanks for the link Lisa. Pictures/videos always worth a 1000 word's.:) I've replaced the thermal paste on a few 1st gen. Mac Pro's...and it's definitely a delicate process...and a little bit of a pain in the butt to even get access to the massive CPU heatsinks to remove them...and you need a REALLY long allen wrench which is shown in the video. Here's the ifixit.com procedure for the same project (replace CPU's on 1st gen. Mac Pro)...which involves the application of the thermal paste. [URL]https://www.ifixit.com/Guide/Replacing-Upgrading+Mac+Pro+Processors+(Early+2008)/17562[/URL] Similar to what you mentioned Lisa about replaced the thermal paste on some MacBooks...I've done it on some older iMac's as well that had discrete video hardware. After replacing the thermal paste...the random lockups stopped.:) - Nick [/QUOTE]
