If possible you need to try switching out each part, piece by piece, with known good parts, or conversely, known good configurations.

For example, try the ram in another PC that you know works. Remove the known working ram, replace with the new ram. If it works, its not the ram.

Same with every other part in the build until you find a culprit. (processor being the hardest if you don't have another known good mobo with the same socket)

Also, make sure you assemble the whole PC OUTSIDE of the case before you put it in the case, as a screw or other short can cause all sorts of bad stuff to happen.

In a case like this, my first guess is the mobo itself, as mobos have a much higher failure rate than ram. Cant know unless you troubleshoot it though.
