after replacing my Motherboard because of Display Problems my CPU is not running any more. I got the following error messgae when running the diagnostic tool:
Error code: 2000-0511
Msg: The (Processor Fan) fan failed to respond correctly.
The latest BIOS is installed.
1. Freshly installed motherboard is faulty
2. When motherboard was replaced fan was accidentally not connected.
3. Motherboard replacement is just a coincidence and fan is faulty.
If Dell serviced it contact them to sort it out.
