i bought a new case, hard drive and motherboard. i bought the case and mother board to move my pc parts from one machine to another. i got the hard drive to run raid 0. here are the specs:

APEVIA (ASPIRE) X-QPACK (new)
eVGA 131-K8-NF44-AX Socket 939 NVIDIA nForce4 SLI Micro ATX AMD Motherboard (new)
Sempron 3500+
512 mb ram (2 x 256mb)
160GB Wester Digital HardDrive
200GB Maxtor HardDrive (new drive)
eVGA 6600 PCI-e 256mb

i put the computer together but im having some major problems, heres a list of problems:

1.) the power supply wont start up on 115 volts but it will startup on 230 volts.
2.) the motherboard powers up, the cpu doesnt boot, but everything runs, fans spin, cant tell if the hard drives are running. strangely enough my mp3 player will charge on the motherboards USB port

Have you tryed to set it up out of the case to see if it was shorting out on the case.

yep i attempted that last night.

it could be the switch is in wrong on the psu or it could be on its last legs.

try it with only one stick of ram and one hd,no dvd drive no gcard or usb devices, if it boots you need a new psu, i would guess you will need min 350w but you dont want to try to save any cash with your psu as when the giveup they normaly take somthing with them.

if it boots with no gcard,leave it for a couple of min then, alt+f4 then right cursor once, enter, and that will shut down.
