Hi guys, today I needed to disconnect all cables from the PC tower to do something with it, and later on reconnected them. However, now the monitor doesn't seem to be working properly, as it gives the "going to sleep" message then a black screen. I have checked inside the tower and nothing seems to be loose. There are two cables connecting the monitor: power cord and HDMI cable. I have tried using a VGA cable, but that doesn't work either. Any help would be appreciated!

can you provide make and model of the PC, and video card if it is a custom build?

 

Or is it an OEM (Dell, HP etc)...

Have you tried changing the source/input on your monitor?

Hello, thanks for the replies. I'm not sure about the make and model about my PC. I use a GeForce GTX 650 Ti BOOST video card.

I got my monitor to work by using a device with a VGA socket that plugs into a DVI socket. So basically I plug the VGA cable into the device, which is plugged into a DVI socket. Although the problem has been resolved, I still feel concerned knowing both my HDMI and VGA sockets don't work. Does any one know why they are not working? If this information helps, both the HDMI and VGA sockets are connected to the motherboard, while the DVI socket is connected to the video card. So I'm guessing it could be those sockets on the motherboard have stopped working?

the monitor is getting both  analog (vga) and digital (HDMI) signals going into it, there is an internal monitor menu that toggles the two. sometimes they auto-detect, sometimes not.

 

 

most BIOS editions have a  toggle between mobo onboard signals and PCIe (PEG)
