Hey guys, im having trouble with the new core i5, i put together a system for one of my buddies and started having corruptions errors half way through the installation of windows 7. i figured it was a bad copy and burnt a new one but had the same problem, i ran diagnostic tests on everything and they all passed, however when i individually tested each core on the i5, only the first one passed any of the tests... Are 3/4 of the cores bad? or are the diagnostic tests on hirens boot cd just not up to date with the new core i7/5 tech?? I'm going to have another shot at it tomorrow and hopefully i can come to a conclusion... i hope its not the processor but thats what the tests tell me... has anybody else had any problems with all 4 cores not working? also im using a GIGABYTE GA-P55M-UD2 LGA 1156 Intel P55 mobo, is it possible the other 3 cores aren't working due to a motherboard problem?? also is it possible that the cpu just isn't seated right? i don't see why only 1 core would work
