hi the shop has changed the memory, dunno about the voltages etc , also tried loading on ide and sata drive and ide and sata hdd's
I cant think of anything as the shop build the same systems every day with what i bought and they have no problems.
The m/b was replaced to another machine and worked as with the cpu,memory,drives,hdd,cables,psu, but all placed together somthing must conflict and the computer shop will not repace under warrenty untill the find a faulty part
