The heatsinks of whatever parts that have heatsinks. I try compressed air first, then open it and want to see a spotless interior.
Heat bad... clean good.
I have a Lombard G3 PowerBook 400 mhz with 30 gig hard drive, partitioned with OS 9.2.2 on one side, OS X 10.2 on the other.
PC card for one firewire port.
It crashes when it gets a little too taxed by programs like Photoshop or is downloading software updates. That isn't good cause I have to do a total reinstall then.
I ran Memtest, a unix based ram tester "http://www.memtestosx.org/" and discovered the original 64 mb was bad and took it out. That left the machine less prone to crash on Photoshop start-up but that was about it.
The remaining 256 mb runs with flying colors using Memtest but the crashes continue. All I have to do is run Radial blur in Photoshop and it is toast.
I was told by an authorized Mac tech guy that some other component is bad on the laptop and needs to be replaced. He said it is a hit or miss to do this. The Unix base in Mac OS X does not like any components that are not running perfectly.
Is there a way to test the other components? Any other options would be helpful. Thanks in advance!!
