problem wise, could be mobo, hard drive, power supply, or windows just needs to be reinstalled.

normally when switching out a mobo, unless you get the same exact mobo, you need to reinstall windows clean or you'll have problems running windows. which what I would suggest is to back up all your data, then download and run a hard drive diag test, make sure the drive is ok. if it is, then perform a clean install of windows.

If it still gives your problems after that, then I'd say time to look at hardware, memory, mobo, and PSU.
