So i had installed Windows 7 and the first few days it would run fine.Two days ago it started to bluescreen on me after i had the pc on for at least 10 hours.In the two days that it BSOD'd the error codes were different.So,i installed windows 10.Then today after the pc being on for about 10 hours or so it turned off,but this time no bluescreen and no errors,even when windows started up it didnt say the error that is displayed after an unexpected shutdown.It just booted up like nothing happened.Any one know how to fix this or what it might be from?
