The place I took it to tested every piece. I tried everything. I reinstalled it all, took out ram, switched slots, took out card, checked cables, used different cables, etc. etc. etc. They tested every part and the MoBo was messed up. Sending it back today and hopefully I'll get the same speedy delivery I did last time. (2 days from newegg.com and didn't pay for any special shipping) Was pretty nice.
