If you have an older PC case that doesn’t give you any visual feedback when it’s turned on, you may have to check for other signs of activity, such as spinning fans or a rotating hard disc. You can confirm that both units are on by inspecting the tiny LED lights they typically have. Your monitor and your PC both need to be on and receiving power to generate a display. We don’t want to spend a long time mistakenly fixing a loose connection or a faulty component and then have the actual issue turn out to be a simple one-click fix.Īnd, to be honest, you’d be surprised at how often we miss the things that are in plain sight. It’s important we get the seemingly obvious out of the way first before moving on to the more problematic causes of a no-signal display. Keep reading for a step-by-step troubleshooting guide on restoring connectivity between your PC and monitor. Important tip: I strongly recommend removing any extra display cables to multiple monitors to ensure that you don’t have other factors causing your monitor to stay blank before you continue your troubleshooting. While a no-connectivity issue is quite frustrating to run into, you’ll be able to deal with it at home most of the time. To fix it, adjust the input source, connect the cable to the GPU, and check for loose cables. If your PC tower won’t connect to a monitor, it might be because your display is connected to the motherboard, your set it to the wrong input source, or there’s an issue with the cable or graphics card.

Similar steps Unplug the computer, remove the battery for a couple seconds (some people will say minutes. Many people will just pull the battery instead. Short the 2 pins for a couple seconds and then plug the computer back in and turn on. Even when a computer is shutdown, there is still power to the motherboard.Ĭlearing the BIOS is described on page 1-3. Something else may have been knocked loose.Īdding and removing memory sticks is a pretty safe thing, but one should ensure the power to the computer is off (ie, PSU unplugged).The memory slots are very close to the GPU slot on that board. Did you knock the GPU out of it's socket when working.


Because that CPU has no integrated GPU, the on-board HDMI (or DVI) would give you no signal. Did you plug your monitor into the HDMI (I assume) on the motherboard or the video card.Mixing memory can lead to issues, but I have also often seen memory sticks that were not seated all the way causing the start, run for 2 seconds, and restart symptom you describe.
