I just built a computer (first time), I bought as a barebone from TigerDirect. I spent a couple of hours building it and at least three times those hours trying to figure out why it wouldn't boot. All my currently installed fans (Case fans and heatsink fan) spin for half a second. I used the sticked 'no boot' thread to no avail. Since I bought it in barebone I assumed that the parts were all compatible to one another. Any help would be appreciated, thanks.

Note: The PSU was built into the case when I got it.

Specs:

CPU: AMD A4-6300
Motherboard: Gigabyte GA-F2A78M-D3H mATX MB
RAM: 4GB DDR3 1600 Adata XPG V1 Memory (x2)
HDD: 1TB WD Blue 7200rpm SATA
PSU: UltraBlaster V2 450W

So what post code are you getting from your internal speaker(point 17)? per http://en.wikipedia.org/wiki/Power-on_self-test



When you went thru the checklist, what voltage readings did you get on your power supply?
"Next best thing is to get (or borrow) a digital multimeter and check the PSU.

Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire: 5 volts always on. Tolerances are +/- 5% except for the -12 volts which is +/- 10%."

I tried without the hdd connected, thinking it was a low psu power problem and nothing changed. I have both 8 pin and 24 pin connected.

EDIT: Now my fan isn't spinning when I turn the power on. I checked all my cables, they are connected.

I'll have to borrow/get a multimeter tomorrow since it's too late in Canada. My PC literally turns off in less then a second so it doesn't reach POST (assuming I understand what POST is, I am fairly new).
