Try a full power refresh and check if that fixes it.
Turn off the PC (if it is on) and disconnect the power from the PC.
Open the case and then locate and remove the RTC coin cell battery¹ from the motherboard. (see image below)
Press and hold the PC Power On button operated for a full 30 seconds and then release it.
Reinsert the RTC coin cell battery (+ve on top as marked on the battery), reassemble the PC, connect power to the PC and check if it turns on OK with a display etc.
If it does there may be a message stating that the Date and Time are incorrect. This is normal as the BIOS has been reset by the above procedure. Once the Date and Time have been corrected, the message won't appear the next time the PC is started. Also, any user definable BIOS settings that were altered by you to suit whatever system requirements you needed, will have to be charged back again as well.
Here's an image of a motherboard that is used in your model PC showing where the RTC battery is located, that may help.

¹ When the RTC coin cell battery is out, measure its voltage. If it is <2.5V DC or if the battery is >4-5 years old, replace it. The battery model number is on the battery e.g. CR2032. If it is a CR2032, these are commonly available everywhere, e.g. supermarkets.

Hi @robertmurp77314
Can you try another known working monitor or try connecting the existing monitor using the other display output option on the PC i.e vga port or DVI-D port?
Can you get into BIOS on startup with a working display? Turn on the PC and immediately press the Esc key a few times. If the Startup menu displays press F10.
What OS is installed in the PC, WIn7, Win8.1, Win10?
