I got a few new components to stick inside an old case for my girlfriend to use:
Foxconn 661FX7MI-S Motherboard
Intel Celeron D 347 3.06GHz CPU
512MB PC3200 RAM
I put it all together, and on pushing the power button, all I got was the CPU fan spinning, no video, no POST beeps, nothing!
I took it all back out of the case, unplugged all the components, left just RAM and CPU, still nothing.
Sent it all back, turns out the motherboard was faulty, got a tested replacement, other components tested too, still havin the same problem.
