Hi There, I hope someone can help. My son's PC failed so it was time to upgrade. I bought a new Gigabyte GA-MA69VM-S2 motherboard, new AMD Athlon 64 X2 4000+ Dual-Core Processor, new Patriot 2G SL DDR2 Ram and a new Power Supply. I'm using the old case. I've been out of the hardware upgrade process for a little while but there certainly didn't seem to be anything out of the ordinary. Turned on the power and turned on the PC and NOTHING. Nothing seems to work, no power seems to be active and I'm stumped as to what to do next. My case doesn't have a CI (Chassis Intrusion) or CLR_CMOS (Clear CMOS) connection and apart from those 2 minor omissions, everything seems normal. Does anyone have any suggestions on this one?
