Best method for TSing is by removing the MB, placing it on a flat, INSULATED surface and connect the bare minimum to get it started.
If you have two mem mods, use one. If it don't work, swap em out.
If you think it is power, connect a new PSU.
If you eliminate all possabilities except the MB and CPU...well your in a bind...
Don't forget to use an ESD Strap.
