Hey guys my friend has just built his 1st PC and it booted successfully but when he did a windows update and it prompted it re boot it did but now it won't switch on ? Any ideas as to what it is
Btw he is using windows 8 and Haswell CPU with gtx 760 and a gigabyte z87 chipset motherboard
And his i5 4670k is cooled by nzxt Krakan
