Sorry to hear that you are having computer problems!

If there is a problem with an item of the hardware I would suspect the PSU first off as it is not only low powered it is also a poor quality brand, see http://www.10stripe....d/psu/brand.php

Do you have or can you borrow a known good PSU for testing purposes, can I ask did you do a bare-bones set-up outside of the case first.

Are the CPU fan and all other connections securely connected to the MB.

/facepalm Yes that would. Carpet is a good place for static to build up and the smallest amount can severely damage components.

Additionally see below;

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.
IF your MB doesn`t have a power test switch 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.
