Trouble with new rig

Ok, basically I've just bought all the componants for a new rig for a friend, put it all together and that, but whenever I turn the computer on, the monitor won't work. The monitor itself works (works with my rig anyway), but whenever I turn on my friends rig, it powers up but the monitor stays off. I'm pretty sure everything is connected correctly. I've tried plugging the monitor into the mobo & the graphics card, neither works. tried booting with/without both sticks of RAM, still won't work. Desperately need some help before I take it into my local computer shop, but I know they'll try and make out that the problem is worse than it is and charge me ridiculous prices. Specs are as follows:

1 x Mushkin Silverline #996768 4GB (2x2GB) DDR3 PC3-10666MHz 1333MHz Dual Channel Kit
1 x 500GB Seagate Barracuda 7200.12 3.5" SATA III Internal Hard Drive [ST500DM002]
1 x AMD Bulldozer FX-4100 3.60GHz (3.80GHz Turbo) Socket AM3+ 4-Core Processor
1 x ARIANET Synergy Black Midi Tower Chassis w/ 450W Power Supply
1 x PowerColor AMD Radeon HD 6850 1024MB GDDR5 PCI-Express Graphics Card
1 x Samsung SH-S222BB/BEBE DVD Writer
1 x Gigabyte GA-78LMT-S2P AMD 760G (Socket AM3+) DDR3 PCI-Express Motherboard

The PSU which came with this rig didn't have a 6 pin connector so I took the PSU out of my rig and put it in the rig above. vAny help is appreciated.

Tried another monitor on it, no luck. I had the exact same problem with my rig, but I can't remeber how I sorted it out. Is there anyway I can check if it's a dead motherboard?

There's no beeps, I've tried removing the graphics card and plugging the monitor cable straight into the mobo with no luck :( Same cable is used for my rig and this new rig and it works fine. Is the mobo dead? :(

I had this trouble with the fx4100 apparently alot of the time the mobo needs updating as alot were relesed before the chips came out, i never bothered fixing it as i found out my 1090t wasnt dead :D

I had a similiar problem, check yo make sure you've plugged in the PCI-E oiwer bus.

it'll go form teh PSU directly into the mobo.

mine had a cable that let u use 4, 6 or 8 pins, so it took some trial and error to fianlly figure out it only wanted me to use 4 plugs.

before i figured that out nothing (not even fans) would start up, and after it worked perfectly.

Many AM3+ motherboards don't actually support the AM3+ processors out of the box. They require a bios update, and to do that you need to have an AM3 cpu on them. So see if you can get an Athlon II or a Phenom II from a friend just to do the bios update (or to confirm that the board is dead). It may be a bit of a hassle, but it's still better than waiting for a replacement.

so, fans come on? motherboard light is on? can you hear your harddrive working, as though its loading windows?

They're supposed to update the bios you. Sending you back another board you can't use would be f...ing retarded.
