Computer won't turn on :(

[Kroze]

I'm building a computer and everything is put together. for some reason, when i turn on the computer, it doesn't go on. The powersupply doesn't go on at all. I tried reconnecting the cable to the mobo. replugging the power button cord to the mobo, switching the power supply with a 250 watt one. nothing works. is it because of my refurbished motherboard?

I have:

Athlon XP 1500
256mb ddr
liteon 40/12/48
plextor 16/10/40
Pioneer 16/40
LS120 drive
Geforce 2 ti
40 gig 7200rpm
2 lan card
1 modem

-------------------------
a 400watt Power supply....which i can't power my system up right now. I tried switching it to a 250watt and it still doesn't power up.

Could this mean that my refurbished motherboard bought from newegg is bad? what can i do to further test which part is broken before i can RMA it?

try running the mobo and cpu outside the case. lay down some anti-static bags on a table or something and put the mobo on there. connect all the cables as necessary and see if it turns on.

A friend of mine has a problem similar to this. We're thinking something is shorting between the mobo and the case.

oh yeah, and wrong forum, dude. 😉

If you're sure both of those power supplies are working and you checked all your connections, then I think it very well could be your refurb motherboard. Do you have the voltages on the power supplies set to 115V?
