So I received my G5 knowing that it would have an issue, turns out it is a processor. Ran ASD 2.6.3 and it would lock up in the middle of tests with LED #2 and #7 being illuminated, and would freeze within ten minutes. I know LED2 is a CPU failure and LED7 is a STOPCHECK light, and when it was booted under Leopard each processor core were within 10*F of CPU A and B. My question is, is the processor toast and should I look for a replacement or should I check the LCS? With the cover off both pumps seemed to feel about the same temperature and both pumps were working. I was able to keep the thing on for a solid 45 minutes straight till I turned it off so I could take it home from work. I'd love to repaste the processors and try that out but unfortunately my T handle screwdriver for the earlier G5s is too small for the Quad -- Also it is a dual pump model with no leakage anywhere.
