Hi everyone, my cyberpower desktop was working fine for the first few months, and then one day when I turned it on I got the error message on my monitor "no hdmi signal from your device, and the monitor would go to sleep and I couldn't see anything. I changed the hdmi port, hdmi cable, got a hdmi to dvi converter to see if that port would work, but nothing works. I haven't been able to use it for months now, and I'm not sure how to get it fixed. I should have contacted cyberpower when I was still within my 1 year warranty but I was stupid and just used my laptop instead. Does anyone know what the issue is? The graphic card already gone bad?

Post your full build specs.


What PSU do you have? Hopefully not the standard junk. May be the issue or GPU.

Check to see if your monitor is OK, can you connect it to your laptop?

Make sure all components are seated and plugged in.

Do you have integrated GPU on your MOBO. If so remove the GPU and connect the video to your MMOBO.

Change the slot the GPU is in.

Hi, thanks for the reply. The monitor works fine on other computers, so it's not the monitor I think. It has the AMD RX 480 4gb GDDR5 graphic cardd, Intel i5 6402p processor, 8gb ddr4 ram. 1tb 7200rpm HD, 600w power supply. I'm not sure about the motherboard, or if the GPU is integrated. I got the $700 build from Amazon.the link to it is dead or u would link it. Ok I will try to do the things you mentioned, I'm not too savvy with computers as you probably could guess. If I cant get it to work, should I just buy another video card? Thanks for the help!

That will most likely have a junk PSU which needs to be changed. Look at it for a brand name. Amaz/Wally/BB/NewEgg, etc. models use lower end RAM, unknown MoBo's, etc. The GTX 1060 3GB can be had for under $250, would be a good idea if the old GPU has died.


If it doesn't Light Up, Turn On, or Plug In, I don't want it!

Do you hear sound from the computer when you turn it on?  If the PSU is bad, it usually just dies and the computer wont even start.

I would plug the monitor into the onboard video and remove the old video card - *IF* you hear the fans and see the hard drive light flashing like it is trying to start.  If it is dead, it is the PSU or worse...
