I am having a bit of trouble booting up my first homebuilt computer. I'm building an entry level system for general office work:
intel Celeron Dual Core E1400 2.0Ghz
Foxconn 946GZ7MA-8KS2H Motherboard (LGA775, Intel GMA 3000 integrated graphics)
Single stick 1Gb PC2-5300 667mhz Ram
DVD+RW, 40Gb HDD.
ASUS SFX mATX 250W PSU (1x 24pin, 1x 4pin, 4x molex, 1x fdd, 1x sata)
I built it altogether and the system won't POST. No beeps, no signal to monitor. However the machine does power up and I can see all the lights and fans come on. The DVD+RW opens too. I've tried to boot up the system out of the case, in case the brass stand-offs might be shorting something. Still, no result. I've tried to boot up whilst having just the minimal components (CPU, cooler, motherboard, PSU, Ram), and no success either. Thermal paste/cooler, correct wire connections have all been checked numerous times.
I tested each one of the components above separately on my current working machine and narrowed down the problem to the motherboard. However I am not yet sure whether the board is actually faulty, I have other suspicions:
Foxconn 946GZ7MA-8KS2H motherboard takes a 24pin and an 8pin power supply. However, both the ASUS PSU and my working machine's PSU have a 24pin and a 4pin supply. The Foxconn manual "strongly recommends" me to use an 8pin - but states that a 4pin can be used if I really have to - I just need to stick it in the top half of the 8pin. However the motherboard fails to POST.
Unfortunately I don't have a 4pin-to-8pin converter so I can't tell whether this is a power problem or not. I have read in numerous forums that the 4pin would normally work on an 8pin. If that was true then it would definitely mean that my motherboard is faulty. However I was wondering if there are certain motherboards that actually can't take a 4pin? I would be very grateful for your expertise.
