I have just built my fifth PC--I used a DH55HC MB and a intel core i5 cpu. I have two seagate500 gb HD's and my OS is windows 7 The problem that I am having is that MOST of the time when I "restart" , the boot up process freezes up on the opening page for the MB (which has the intel name)I need to hit the "reset" button on the front of the pc to get it to boot up properly. If I just "shut down" the pc and manually click it back on--then it starts fine. Is this a MB problem or a OS problem????
