Wedge,
Could you give us greater details on your new system. Please list all the hardware, OS, and Power Supply.
I really need the list of hardware (including - Mobo, RAM, CPU, Vid Card, PCI Cards, HDs, Optical Drives.) and the amps on the 3.3v, 5v, 12v RAILs and the Max Combined Wattage for the 3.3v + 5v RAILs. It should be on the sticker on the side of the power supply.
That would give us a complete picture of your system.
Take Care,
Richard
