i just finished gathering all the parts for my new comp, and when i turned it on, the fans and everything powered up then immediately powered back down. the mobo light remained lit, however. i tried running it without the 2x2 power connection and everything seems to run fine (but obviously w/out a cpu). the fans will run and the monitor works (but with no feed of course). any ideas what the problem is, and could some place like best buy test any of my parts for me? mind you these are all new parts from newegg, but they coule be faulty. thanks in advance!
