so i finally finished my new PC but here is the prob when i turn on the power all the lights come on the fans turn the works but it shuts off after 2 seconds right away, the CPU is fine cause its brand new and i don't think its the MoBo cause the network LED is on all the time meaning there is current going through and whatnot the ram should be fine and there is no graphic card cause its integrated so ya um whats up :(

also forgot to mention when there is no CPU in the socket the MoBo stays on it does not shut off so it has to do with the CPU i guess buts its brand new. also i already tried clearing BIOS

Sounds like the system is shutting down do to cpu overheat, make sure the cpu fan is connected to the correct place on the motherboard.

make sure the heatsink is down tight

no its not that i tryed different fan plus they all do the same also the CPU cant overheat i exacgerated when i said 2 secs its more like a fraction of a second like litterally the cpu cannot go form air temp to burnout degrees ina fraction of a second and if it can well my heatsink and fan are properly mounted and plugged

CPU: AMD Athlon 64 3500+ Vience Core
RAM: 512MB Hynix DDR 400 Ram
MOBO: Asus A8N VM
HDD: 250GB 7200RPM 16MB cache IDE maxtor
CD DRV: Sony DVD +/- RW
CASE: Ultra Microfly
PSU: Came with the case (i got the blue case with no window on the side)

ok so those are the stats, i dunno y but im thinking maybe it has to do with the socket of the mobo i have this weird feeling that i got thermal paste in the hole/s is there a way to clean up the socket should i rub some rubbing alchool or something?? there must be a way to clean inside the socket.

Hi!
I agree with the others - this sounds like a PSU problem. Have you checked the 4-pin 12-volt power connection on the mobo?

Open the case and get the Power supply information off the side of the unit including the amps on the 12volt rail.
It seems to be an underpowered power supply, generic power supplies do not put out the power they claim.

EDIT just googled your case and it comes with a 400 watt PSU, you need at least a 500 watt GOOD QUALITY PSU see the link in my signature.

ok so i was doing some multimeter tests on my PSU it seems that if the 4 pin 12V connecter is not in everything stays on just nothing happens as the CPU is not getting any power but i checked the voltages and i get 11.91V which is acceptable, my molex gives me 12.01 and 4.93, i just find it weird could the CPU be defective??

Your power supply is not defective but being a generic brand it is not putting out the amps that it says it does, so that means your 420watt power supply is really a 300-350 watt supply.
Buy a PC power and cooling,seasonic,antec,ocz, fortron.

Check and make sure the clear cmos jumper is in the correct position, it normally goes on pins 1&2.

Make sure the cpu fan is connected in the correct place on the motherboard, if it is not the board thinks there is no fan and shuts down.

Make sure the hearsink is tight, a cpu can overheat in a matter of seconds and force the board to shut down.

I know you said you don't think its overheat but double,triple check because any one of these things will cause the symptoms you describe
