Hi just put together some new bits on an old case and it won't work - won't post no fans working no beeps HDD silent mouse light does work though. Spec: Mobo(brand new) - Gigabyte GA-H61M-S2PV v 2.0 PSU(brand new) - Corsair CX430 Builder Series v2 CPU(brand new) - Intel Celeron G530 RAM(brand new) - Kingston Value 4GB DDR3 1300MHz Case(had since 2005) - Antec P150(without the Antec PSU) I tried first with the original Antec PSU that came with the case but that didn't work with the same symptoms as above so I thought it was the PSU at fault and then replaced with the one above. I've built 5 or 6 PCs over the years without any problems in the past. Its been a couple of years since my last build so I might be missing something obvious. The power is getting into the mobo as the light is lit up on the IR mouse. The power switch led briefly lights when pressed but no noise at all, no movement at all in the system. I've reseated all the power connectors and wiggled them. Same with the ram. What can I try next? Any help appreciated.
