motherboard wont boot

[EDO-7]

I just recently bought a Gigabyte GA-7VA Via KT400 Athlon(XP)/Duron SktA DDR ATX Motherboard and put a amd athlon xp2100 chip and when all the devices were installed the computer did not boot. Any suggestion why the pc might not boot.
Please help.Any info would really help.

Does it power on and the fans turn on?

Just curious, was this a "hot swap", meaning did you just replace the mobo/cpu without formatting/reloading your OS? Have you tried booting in safe mode? Have you tried clearing your cmos?
Do you hear any beeps? You say it does not boot, what exactly does it do?

Also, what are the rest of your system specs?

it does not power up but the heat sink fan kind of twitches when you turn the switch on.Niether the fans are powering up.

No its not a hot swap. I basically bought all the devices new.
installed them and it did not boot.
I have a Gigabyte GA-7VA Via KT400 Athlon(XP)/Duron Skt A
Amd athlon xp 2100
256 mb of ddr memory
western digital HD 40gb
liteon 52x cdr/rw
32mb ddr ati radeon 9000 videocard

Thats about it...

I suggest stripping your system down to the "bare bones"...just leave your cpu/video card attached and power up, see if you get that H/S fan spinning. Add the memory (1 stick at a time if you have 2 x128 sticks), hard drive, etc...that way you might get the system to boot, then not boot after a specific device is installed. Troubleshooting down to the hardware problem basically.

any idea anyone?

Sounds like something with your PSU, if it twitches a little bit. Do you have another PSU to try?
Also, what is the PSU wattage you are using?

tried to just power up with the cpu and video card and no luck.

Well, you are going to need RAM in there as well to power it up. It sounds like a power problem.
