hi there, * I'm on caos for 3 days... * To resume my history, I bough a used mac pro 3,1 (early 2008) with 500gb HD / 4x1gb RAM / Geforce 8800T on ebay and brought it to Brazil. Then, when I arrived (10/8), I upgraded it with more 2x2gb RAM and a intel 330 SSD 120gb. I splitted the SSD and intall os 10.8 and windows 7 trough bootcamp. Install all others softwares on both OS. It seems to be ok, except that when I leave it on OS X and it start to sleep, the computer shuted down by itself. Didnt happen on windows. Until friday morning (10/12) that it didnt want to boot. It turned on, chimed, show gray screen an logo and shutted down. It went safe mode and nothing... After a long time of trying, I booted on single user mode, runned fsck command and realized thas has an error on SSD. I booted from a Lion DVD and install it on original HD. Formatted the SSD partition and seems to be ok. * On saturday morning, same history. I made a lots of tests, took SSD out, new RAMS out, rise cards, PRAM reset,.... The diagnostic leds, didnt show any problem. After a lot of tries, I boot from original HD and after I booted from all others OS. * On sunday morning, same history.... * On monday morning (today), it was really hard to booted, after success, it shutted down again... Now, it blinks to 2 lights after shutted down on diagnostics LEDS (5 and 6). So I decided to dwonload the apple harware test from web, since I dont have the originals DVDs and holding D wasnt working. 2 times on the middle of the test, it shutted down. Then, i took off the rinse board number 2 and left only the 2x1gb original on rise 1. Perfomed an extended test and showed an error: 4sns/1/40000001:vmas-0.000. I tried to search this on web, but didnt find anything about vmas error. * Here, we dont have a genius bar as US, that we can test the machine in front of the client... I really apreciate any though or ideas about my problem. * Regards all!
