PC wont quite power up

Hey everybody, Just brought a new power supply because the old one wasnt grunty enough for the new motherboard. I installed it, but when I turned it on, it started for about half a second and then turned off. The fan on the cpu and power supply flickerd but then died. The other times I turned it on it did nothing, not even flickered.

I have tried remounting the video card/memory and disconnected all other drives etc, but no luck.

Please help me!! Happy

My system specs are:
AMD Sempron 2800+ Socket 462
Soltek SL-75FRN2-L MB
256MB video card
430W PSU

PSU works

In reply to: Did the old PSU do the same

Yeah tried the old PSU and still no power.
Although I just tested the new PSU by shorting the green and black connections and the fans turned on, so I guess the PSU isnt stuffed. Makes me wonder if the motherboard is faulty. I'll be gutted if it is cause I just brought it! Sad

Is there anyway to test ya motherboard without borrowing another one?

assuming that when you tried it afterwards and not even a flicker from the CPU fan, im wondering if you took steps to protect your new board and other components from electrostatic discharge, such as wearing a antistatic wristband or similar, have you tried settn the system up with only what you need to boot up leaving everything else unplugged and is successful, repeat the process plugging one thing in at a time to determine the problem device

When I changed everything over I did use a anti-static wrist strap, so pretty sure it wouldnt be that. Tried setting it up without anything in it, but still nothing.

Would it be possible that the old PSU might have taken either the CPU or Motherboard out when it crapped out?
My flatmate was using it when it stopped working and she said smoke came out from the back of it, but that could have been the PSU for all I know.

happened to me

I forgot to plug in the second power cord to the motherboard. I know it sounds dumb but make sure you plugged all the power cords in. If the mb doesnt have that second power source for the cpu, the symptoms are very similar to a dead mb and proc.

not missing plug

In reply to: happened to me

I did that exact thing when I first got the new Motherboard. Took me ages to figure it out!
But I remember to do that now, so its not that unfornunatly.

smoke came out of the back?! if i were you id be pretty annoyed with that flat mate...you should probably open it up to look for any damages...see if it was the PSU or not

checked it

In reply to: hmm

Yeah I was pretty pissed with her! I've taken everything apart, taken it all out of the case and checked it for visual damage but couldnt see anything.
I would asume it was the old PSU that made the smoke since it doesnt go anymore.

Is there anyway of testing the motherboard with a multimeter??
