Retrofitting a P4 3.2mhz machine with a Core 3 Duo 6230, Intel Motherboard, 2 GB Ram, Western Digital 250 GB SATA II HD, Nvidia 7300GS video card and a couple of DVD drives.
Power Supply is a new Antec HE500.
When I turn on the machine, fans kick on for a few seconds, I hear the HD Spin, and the machines shuts down.
if I remove the memory, MB beeps like hell.
24 Pin connector is securely fastened
2×2 connector is also firmly connected.
If I unplug the heatsink fan, machine runs.
What the hell is going on?
I checked the seat of the proc. Looks good.
Heat sink is securely in place.
There are no extra brass posts under the board.
Symptoms are a weak power supply but it is a new 500 Watt Antec.
Anyone seen this before?
