@MarcLee326 , welcome to the forum.


Since you computer was released in 2009, it is very difficult to know which component is causing the problems.  My first two suspects are the power supply unit (PSU) or the video card.  If you have Integrated Video, you can remove the video card and connect your monitor to Integrated Video.  If the problem is solved, you will have to replace the card.  If not, you should test the PSU to see if it is failing.  Please let me know what happens.

As that unit is circa 2009 I agree with you about the unnamed Video card.


When your asking about an issue, it is very beneficial to know what you installed.  That unit is Legacy BIOS, and can not ever use a UEFI video card (aka modern card).
