|It depends on why it froze. If you restarted it and nothing showed on the screen--no logo, no posting screen and no error messages then you've got a major problem. (If you are getting something on the screen post back exactly what it's showing.)|
You might try removing the hard drive and then starting it up. If the problem is the hard drive then you should get the normal posting process and then an error about 'no boot device' or something similar. If it happens that way then you'll need a new hard drive and a fresh OS install on it.
If the screen is still blank with the hard drive removed then you probably have some internal not-easily-repaired problem.
