HP xw6400 Workstation Won't Boot Up

[dreamspinner3]

My husband has an HP XW6400 work station that won't boot up.  It either beeps four times while a red light in the front blinks four times or it will act like it is trying to start up, then stop, then start up again, then stop.  Once it got all the way into the Windows 7 is starting up screen, then shut off.  We have removed the RAM & reset it, but that didn't solve the problem.  Any suggestions on what the problem could be?

The last time he tried starting it, a black screen came up with different options rerarding starting in safe mode, repair mode, etc.  He selected safe mode & that is when it started having the above problem.

He's gone to the store to get a new CMOS battery for it.
 
Thanks!

Hi

With what you have already done and the information here about that code.

It seems it is likely a power supply fault or excess load on the power supply

there is a procedure there to diagnose the this error.

Another thing to check is damaged USB ports.
If you do have any USB ports damaged report back for a solution .

The link you gave me did not work.  I have a friend coming over to check the power supply.  New CMOS battery didn't make any difference.
