A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52).

Welcome to the Community,
Where you trying to update the display driver through Device Manager?
If you haven't you can try uninstalling and reinstalling the video card driver.In Device Manager expand Display Adapters,make note of the video card listed,right click on it,click uninstall,put check mark for delete driver software,click OK.
Reboot the system and logon to www.support.dell.com ,select Drivers and Downloads,enter system Service Tag number,select Operating System,expand Video,select the Video card (one which you made note while uninstalling),download and install the driver.
Let me know if you need more help.
