Hello Everybody !

Assembled ATX box and MB, installed CPU and heatsink, connected the MB power lead, CPU power, system fan and front panel cables.
When switched on the power supply, the CPU fan starts for a second and then all dies, no beeps.. nothing.

Have I missed somthing? Please help!
Thanks.

Take everything out and put it back again. Checking that everthing is seated propaly. I had the same problem as you when I built my PC. Turned out that my CPU wasn't quite in straight.

Your system isn't going to boot without an HDD or RAM. :D

This whole operation started after the old motherboard was fried. I bought the new MB and at first tried to install and connect all basic components: MB, CPU, HDD, CD, RAM and the Front Panel wires. The result was just 2sec of CPU fan and that's it. I expected at least system fan to start ... didn't happen.

Then I started taking out the components until there was only MB and CPU left. Same result after turning on the power: CPU fan worked for 2 sec.. then all stopped.

Maybe CPU is fried also? Does anybody know the symptoms?

Take the HSF off the cpu, then put thermal paste on them ,then reboot.Either that or you have wires crossed,maybe sleep switch wires or reset wires. . Unhook all wires and use inkpin to croos two pins to start mobo. If this does`nt work then you may have ground on mobo. Try paste first then try jumping the 2 pins.

What CPU do you have and does your motherboard support it?!

If your CPU's FSB is not supported by your Motherboard it will cause this! Meaning if you put a 200Mhz CPU in a mobo that only goes as low as 266Mhz!

I got the same mb that was running this CPU before.

And I have installed HSF using thermal compound although its not clear how it could affect the start.
It cannot overheat in 2secs, can it?

FP cables is the bundle that includes PowerSW, Reset and leds.
Strangely enough, all of them should be plugged in for the fan to start.

And by the way after the CPU fan starts first time it takes some time before it can be turned on again.

I got your manual, and I think this is the pin configuration.
