Hi, please help me...
I just finished to install everything in my case. Motherboard, CPU, heatsink, DVD, CDRW, video card, HDD, floppy, memory, etc.

When I push the start button, the system power up for about 1 second and then everything shut down. Any Idea...

I have a chaintech apogee with athlon 1800+ and DDR memory 2700, if it can help
 
Hi
That happened to me when I first put the noise control silverado HSF on my Soyo board... The board has a protection deal on it. If the fan plugged into CPUFAN1 isn't drawing 12v, it wouldn't power up. I had a resistor between my motherboard and my fans, so it was only drawing 6v. I had to boot it up with the fan running at 12v, turn that feature off in my bios, then put the fan back to 6v
I hope it works for you.
dunu nunu nunu nunu.... BATMAN!
 
thx, but i can't even go into my BIOS. Nothing is booting, I can't even have power for a second...

Heard things about motherboard grounding ???
 
Normally this happens when you first plug in a system but don't hit the start button, but it can also happen if your board doesn't detect a fan on some Athlon systems, of if the board is shorted through a misplaced mounting post.
