i have a dell precision workstation 370 at office .
suddenly it gave roaring fan noise, i checked it was coming from cpu fan socket and the general power supply
fan was working ok.
i ordered the new cpu fan and put it in today still the noise is there
when i plug in to monitor to check bios setting. i cannot see the screen.it is blank so i cannot even go to bios.
the screen is blank whether cpu fan socket is connected or not connected to motherboard.
is it motherboard gone or something else happened.
