Back when the Phenom x4 first came out, I pieced together my build @ NCIX. I checked the compatible mobos on all the relevant websites and finally picked out an ECS board, but that failed to get the system to post, so NCIX let me exchange for another supposedly compatible mobo, an asus M2A-VM. That failed on me too.
After 2 weeks of tinkering and the system stil not posting, I brought it back to the salesman who helped me exchange the mobo for diagnostic and later let me use his personal AM2 processor (can't rmb exactly what it was, prob a Sempron) for me to re-flash my BIOS. I showed up outside his apartment and he dropped it out the window for me to catch, lol
eventually that comp was up and running perfectly but I've never heard of employees lending their own stuff out to get their customer's rigs working. big up to NCIX and the sales team that go above and beyond!
