Jimi Although it sounds outlandish, one or more of those 3 components could be bad a second time around. Does your retail source have verification ability so they/you can be sure you are buying all good products? I'm sure it's been mentioned before, but you should verify that the MB standoffs are correctly installed and that the MB is not grounding out. If I remember correctly, the last issue of Computer Shopper had a very detailed article with lots of pictures on building a computer. If it is not Computer Shopper, it must have been a recent issue of Smart Computing. I hope you can resolve this issue before losing your mind to frustration.
