Hi,

I have a computer that's been built by my brother, filled with brand new components, the case is second hand. It powered up once with everything apart from graphics card installed. When that was installed and connected to a monitor nothing happens. Now it won't power up at all, even without graphics card.
Either something has been installed incorrectly or a new item is faulty, however he can't identify the fault.

It seems like a waste of money send it for a service, so someone can tell me a component is faulty... or maybe it just needs a tweak.

I'm clueless, any advice would be greatly appreciated

ASUS M4A87TD/USB3 - motherboard - ATX - Socket AM3 - AMD 870
SAPPHIRE HD 5570 graphic card
AMD Black Edition AMD Phenom II X4 955 / 3.2 GHz processor
OCZ 550W Fatal1ty Power Supply (I was wrongly sent EU version, I presume they are the same apart continental plug)
Samsung EcoGreen HD103SI 1TB internal Hard Drive SATAII 32MB Cache 5400RPM – OEM
G.Skill 4GB (2x2GB) DDR3 PC3-12800 1600 MHz Memory 240
Case is a Cooler Master

thx, Daniel

Hi Davedog8
Best couple of suggestions I can make would be first remove the MB and do a barebones set-up on a piece of cardboard (make sure it is larger than the MB) only connect the PSU, the GFX card, 1 stick of Ram and the keyboard.
You will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding a component, second suggestion try a known working PSU, it is not unknown for new components to be bad, third suggestion try and loan an ordinary PCI graphics card (not pci-e) again to try and get a BIOS screen.
Other things worth checking include, if you used stand offs beneath the MB are they in the correct locations (only where there is a screw hole in the MB) otherwise the MB will short out, check for stray screws or bared wires for the same reason, make sure the jumper cap that can be used for clearing the CMOS is not missing or on the wrong pins.
Let us know how the testing goes or if we can be of any assistance.
