Hi all. I have a problem. I had a overclocked i7 4820k with my ram running at 2133 all fine. I upgraded my graphics to a gtx 780 and it kept crashing. Blue screen and not letting me in to widows. I set all my stuff back to stock and it loaded to windows fine. Will not load with two monitors in, just one then after its at windows I can put the second one in. I'm Ok with that. Now several weeks later I oc again and it worked fine the first two times, now back to blue screen or freeze just before desktop. Can load in save mode. Any ideas? Thanks
