Hi guys,

I built a PC from scratch for someone today and after the initial building process, naturally I tried to boot it. The PC boots for about 2-3 seconds, then instantly shuts down. I've checked that the CPU Heatsink Fan is spinning, that the PSU fan is spinning, and that the Case fan is spinning. All of those seem to be in working order.

I've changed the RAM chip with a chip from my own computer but it didn't help. The only things that are not new in the case is the HDD, PSU and DVD-ROM. The CPU is a brand new AMD Athlon 64 X2 4400+, the Mobo is a new Asus M2N-VM DVI, with a 400W PSU which I have used in my own PC as well.

Tried powering the PC without a HDD or DVD-ROM plugged into the PSU, but that didn't help either. Am I missing some important cable or setting here? Could the CPU be overheating? It's a brand new out-of-the-box AMD.

I urgently need to get this PC to boot, as I sort-of have a deadline to finish it.

Here are the current specs:

AMD Athlon 64 X2 4400+
Asus M2N-VM DVI Motherboard
1GB DDR2 667 RAM
40GB IDE HDD

Thanks in advance!

New PSU?

New PSU?

Are you sure that when you mounted the motherboard none of the standoffs were shorted against any board traces? The standoffs can be moved to where you need them and removed from where they would short the board.

Also make sure that any jumpers are set correctly, they may be settings for the processor speed or bus speed.

After numerous attempts to try out new hardware, etc, I finally figured out the problem and got it to boot. The HDD jumpers were set to slave, so effectively there was no primary booting device. Moved the jumpers and it starts up now.

Thanks to everyone for assisting me.
