Howdy - So I have recently installed a 750W Power Supply and a GeForce 9800GT + XO and have been suffering a problem where approximately every 30 minutes to an hour the computer will crash, go into the blue screen crash, and then start over. What happens before hand is the computer will begin chugging along and then all of a sudden have a crash in Windows Explorer and then the entire system will fail along with it. I have replaced the hard drive and reinstalled the operating system thinking that could be the case, but I still have the error occurring. I have check all the connections and have solid connections in my tower. And with that I am at a complete and total loss on what to do. I'm going to include the latest minidump files for review, and any information that can be provided willl be greatly appreciated. Thank you in advance.
