By experience it sounds like its the power unit. Just check all the leads are in correctly. What power unit have you got and how long have you had it?

You might also want to check to make sure all fans are operating properly/plugged in correctly.

the power box is kinda old one i wasnt sure if it was because the power box it might be because all the wire and cables are connected right when i turn it on it boot up and everthing with no problem maybe after 5-15 min it go to the blue crash screen dumb memory and restart back up so i cant think why it keep doing that
