Exclamation Major problem with CPU fan or power supply

hey, I am having a small problem, last year after christmas I had built a new computer when I had everything installed correctly I had turned the PC on the CPU fan came on and the power supply powered up, but the hard drive nor the AGP video came on when I was looking inside the case the CPU fan had slowed down and then the power supply turned off. so I had to get my money back for HD and video card. up until now I am testing halfway built PC it seem's like everytime I turn on the PC the CPU fan turns off automatically and the power supply turns off 5 seconds after the fan does..... something told me to turn on the PC without the CPU fan plugged up to the Motherboard. the PC came on for 3 seconds and then shutoff can someone tell me what the true problem is ? also I don't hear any beeps...... should I plug in a speaker to see if I can't hear something ?

thanks

might just be your motherboard.

if you dont have a speaker how do you expect to hear anything?

Does anything come up on your monitor?

Im guessing you dont have a 4 pin molex plugged into the mobo

Defiantly sounds like a power supply problem of not suplying enoug juice (or wires missing) and the mobo autoshut's off

Also if you have a speaker plugged into the motherboard, what beeps do you get? If it's an asus board plug a speaker into the intergrated sounds as well.

PSU's are not connected to the heatsink/fan, they are supplied power by the motherboard which then the motherboard is connected to the PSU through the main power which is a P1 connector, also known as a 20 pin ATX connector.

I tried a 400 watt power supply that I had in a unused
compusa box and I plugged up the power supply to motherboard along with my floppy and CD-ROM and almost everything works!! the whole machine came to life !
I have almost all the parts I need I have the MB, processor,
floppy, CD-RW,CD-ROM, 2 128 SD ram memory and my old 10 gig hard drive all I need now is a PCI or AGP video card and I'm all set!
with the last information I provided about the motherboard, will a regular PCI video card do for now until I can afford a better AGP video card or should I wait and buy a AGP card ?

thanks again for the help
