I recently purchased a new motherboard, due to the previous MB no longer functioning. I have installed the new motherboard, upgraded RAM, and installed a new processor. I am still using my previous hard drives (1TB used for the OS and a 4 TB for all my other data). Upon installing all the components, the PC turns on and prompts me with "Getting devices ready." After about 3-5 minutes the computer freezes up and will no longer have the spinning dots under the prompt. I even left the PC on for about an hour and a half, just to see if maybe by some miracle it would finish. I checked all the connectors and everything seems to be fine. In addition, I am running Windows 8.1 Pro. If anyone has any suggestions, any help would be greatly appreciated. Thank you!
