[NAME]  You can ignore Kernel 41 errors. That's just a generic message meaning the PC wasn't shut down properly. Sounds like you may have to replace that fan. You can read more about the 2000-0511 error code here and some additional testing recommendations.  If this PC is still under warranty, you should contact Dell Tech Support for assistance. The Service Manual has instructions to replace the fan, if you're not under warranty and want to DIY, but you'll probably have to get the fan from Dell Spare Parts because Dell typically wires fans differently than "after-market" fans. BTW: Thread with similar issues and same error message here...  
It's been almost 3 years and the computer, since the first year of use, fails with the screen going completely black, power button remains unresponsive and in a solid amber light. I have to reboot the system by unplugging the AC cord. Have scanned PC for issues with the Dell online tool, nothing is wrong apparently. Windows 10. Have used on two different locations since I moved and both have same problem, so power supply issues could be discarded. The issue appears randomly and never while using any particular software, even when computer is idle.
