Computer no signal ?
I have an asus desktop, windows 10. I have the computer connected to my element tv via hdmi. Today I went to move the computer. I had to plug the computer into a different outlet because the one it was plugged into wouldn't reach to where I wanted to move it to. So I unplugged the computer, unplugged the hdmi, moved the computer and plugged everything back in. Turned the computer on and the tv says no signal. I plugged the computer into a different outlet. No signal. Plugged the hdmi into a different port. No signal. Used a different hdmi cable. No signal. Tried an actual computer monitor. No signal. How do I get my signal back

Maybe all of the video fell out when you moved your computer. I dropped an old iPod and it stopped working because all the music fell right out of it.

Check if HDMI cable is not loose.

You may have affected the CMOS values(bios battery backed up settings). This would happen if you had poor electrical connections eg a bad wall socket, or a loosely fitted psu mains cable or a poor mains extension cable.
Alternatively the system needs to settle at the wall socket it is connected to and the wall socket should remain ON as this allows the PC ON BUTTON circuit to remain live to SENSE the ON button push.The following information is important. When you turn on a pc and the mainboard starts it checks everything and you should get your ONE BEEP. If a fault is detected you may receive a code of beeps eg 3 short two long and the pc will HALT or attempt to START but may do a false start typically this may include a not starting GPU card so you get no display or a small ramdon piece of text on an empty monitor screen(which a TV may be incapable of showing you but a Monitor will display). Also most psu's/Mainboards now have OVERHEAT protection which is to help prevent CPU damage. in the first few seconds of an attempted START, the CPU is pumped full of energy to get it going and the cpu fan revs for a few seconds to cope with it(hint: at this time if the fan revs for more than a few seconds you are overheating the cpu for too many starts too close together). If a user attempts more than 3 or 4 starts within a 1 minute period or less then this energy becomes too much and the mainboard may get a LOCKOUT which specifically will last around 45 minutes. During that time no matter what you try and do the system will NOT start until the approximate 45 minute LOCKOUT timer has elapsed. It cannot be circumvented for any reason.For you check the wall socket is good and reliable and has a healthy GROUND(Earth connection), do not use a mains extension. Switch ON the wall socket and WAIT about 30 seconds to ensure psu and mainboard are ready. If the pc does a random start at that point, hold in the ON button for 5 secs to prevent the start. After a short period of say 15 seconds, your system should now be ready to START properly. Always leave the wall socket ON.if all that does not work then internally you may have a GPU card that has come out of its socket or RAM cards that need removing and reseating because of the move.Once you get your ONE BEEP you are good to go.

- Did the desktop sound and look like it was on? (There are usually some lights on it, the power button glows, or you can hear it turn on.)
- Did you shut down Windows, power off the PC, and was the monitor powered off BEFORE you began unplugging things? (not mentioned)
- When things were reconnected, did your cycle through ALL of the HDMI ports (with the TV remote)? (HDMI-1, HDMI-2, etc.)
- Have you tried connecting your desktop to your plain monitor using a non-HDMI cable, yet?
- If you connect your TV via HDMI to a DVD player or game system does it work?
It's possible that you moved the video/graphics card while unplugging and moving the computer. Are you savvy enough to open the cover and reseat the components? (RAM, all cards, etc.) If not, track down a savvy family member, friend, or hire an IT tech to come out and test for you.

I think it's a settings issue, either with your TV or PC.
Try making sure that your TV is on the right HDMI input source.
From your PC, right click on your Desktop and go into the Display settings. See if it will recognize the TV as a monitor. Play with those settings a bit.
Lastly, make sure both ends of the HDMI cable are firmly plugged in to the TV and PC.

maybe you should take it to a computer place and have them help you with it
