putting new system together and im having issues. if i install one 512 mb ram module in the first dimm the system wont even boot to bios. if i put 512 in the first dimm and 512 in the second dimm, it still wont boot. if i put one 512 in the first dimm and one in the third it boots finally! but im going thru the installation and getting blue screens saying page fault. then it says dumping physical memory and then says done and then rboots again totally messing up my o\s install. this is driving me nuts. any ideas guys?
