At times the computer will show spots on the monitor then either freezes or resets itself. Not sure if this would be a graphics card issue or rams? Any advise would be greatly appreciated!

try and inspect and reseat all connectors for video.try using a different monitor \ cablesremove the power cord from your pc and try to reseat your ram and video card ( if applicable)if you have multiple sticks of ram try removing them all except one and see if that changes anything.try using other ports on the video card.

Hi, Some things to check: i). Check that you have the latest video drivers installed. ii). Try using the Intel GPU that is integrated with the CPU, instead of the Nvidia GPU and check if the problem still occurs. If it doesn’t then there may be a problem with the Nvidia GPU card. You will have to connect the monitor to the motherboard’s HDMI or DP port. You may have to enable the Intel GPU in BIOS. I’m not sure and the user manual doesn’t show it but go to BIOS > Advanced > System Agent Configuration and check that the Initiate graphics adapter setting is set to iGPU. Save the changes and exit. iii). Perform a Win 10 memory test to check if the memory is OK iv) Check in Event Viewer for any Critical, Error or Warning events that are logged at the time that the PC resets that may give a clue as to what is happening. To get to Event Viewer, press the Win key + x key (both together) and then click on the Event Viewer link. If there are entries that occur at the same time, search online using the Event ID and source to find out what they mean.
