It was on and working just fine for about 3 days then today it froze and wouldn't restart.
Hello and Welcome -
You state that it was OK for about 3 days
, can I ask how old the computer is, and how long have you owned it ?
Have you just replaced the M/board, as you make a point of giving the brand Etc. or have you just built / rebuilt it ?
If you wish to post the full details of the system, than please follow the directions in the link below -
