My 8core Macpro seems to have gotten a problem...
For the first time in about 6months i turned it off today to add another 1tb HDD (4th slot), when i turned it back on it just sat there with the white screen and spinning loading symbol for about 5minutes and then finally booted into OSX (10.5.4) OSX failed to load properly, my background images were missing and all desktop icons missing.
I turned it off and tried again, and again it took 5mins to boot, so i turned it back off, pulled the new drive and tried again... and Again it took 5mins to get to desktop, at this point i pulled out my OSX installation disk and tried to run disk utility to see if my main boot drive was dieing, but every time i tried to boot off this disk the computer would hang for 3 or 4 minutes and then CRASH
Macs dont crash, but up popped the grey warning screen "please Reboot..."
So, i pulled my Ram and reseated the standard 2x 1gb Apple sticks and tried again, this time OSX booted in seconds as it should and all seemed well, so this points me towards the 4x 2gb Sticks... I try and run disk utility from boot and again even with just the 2x 1gb sticks in it crashes the computer.
This made me think the 4x 2gb sticks are ok, as removing them hasnt cured my problems, so i stick them back in, start the computer holding down "D" and indeed it succesfully completes the system check with them in.
Anyone got any help, ideas, advice? im baffled, im currently waiting for some new fast HDDs to arrive to replace my bootdrive, but, i dont know how thats going to work if it currently wont let me boot from the DVD anyway.
