Segmentation Faults.
 

Hey guys, im trying so hardly to figure out the problem on this machine...

I've tested the ram via Memtest86, for 6 hours, passed. I've done multipul passes on the harddive, passed. Even with all these tests, this is the 2nd OS i've tried on this machine that results in segmentation faults, whats the deal here?

You're getting segfaults when you try to install? I have run into that before, but it was my ram (thousands of errors in memtest :P),but you've already covered that. I'd try disconnecting your ribbion cables and reseating the ram, I doubt that would be it but it might be worth a shot. If you have 2 sticks of ram as well, I would try testing both by themselves, I've never had memtest miss bad ram, but ya never know.
