HP Workstation Z240 doesn't start

[Specifi_Max]

my HP Workstation Z240 doesn't start anymore.

When I press the power buttorn the motherboard turns on and the CPU fan starts, but after 60 seconds it seems to turn off and restart.

Could you help me please?

Thank you

Specifi_Max,

There are some possibilities to eliminate first:

1.   A memory problem:  A failed or incompatible module    > It seeems there should be an error message or red light /beeping. > Try starting the system on one RAM module at a time. If it starts, try each module to

2.  Thermal shupdown:  Is there a possibiloity that any internal fans are disconneced?   > Check all fan connections

3.  Corrupted BIOS :  Has the BIOS been upgraded or settings - e.g., disk mode- altered recently?

Other possibilities are that the disk is not recognized or a power supply problem.

Start with some of the usual suspects and let us know what happens.
