I have just bought an ABit Kv7-V MoBo and it won't boot. At first I thought it was the PSU (it would click and whirr for a second then die) so I replaced the PSU with a new 550W model from Qtec. It now comes one and continues to Whirrr but that is it, the monitor doesn't switch from Stand-by mode to Active Mode (so no signal). This lead me to think it was the Graphics board not getting the required Voltage so I have replaced that with a new one that is AGP 8x (0.8v I think, but could be 1.6v which is still good with the MoBo). The only thing I can now think of is that the CPU is dead. I don't actually have any way of checking this as the only other Socket A CPU I have is my old Duron900.
