Help troubleshooting a pc

J735 · December 21, 2019

Hi everyone. So I'm kind of new to building PCs and I need some help troubleshooting an issue. Here are the parts:

Ryzen 5 1600

ASRock b450 pro4

Corsair vengeance ram 2x8GB

Corsair cx750m PSU

XFX Radeon RX 580 8GB GPU

Samsung 1TB SSD (qvo I think)

So this is my girlfriend's PC that I built. We built it and it was rebooting during games, so I thought we had a bad GPU. We replaced the GPU at my house (same model) and it worked fine. We played overwatch and everything perfectly. Then when she went home she wasn't getting signal to her monitor. It was just a generic computer monitor she dug up. So I brought over my monitor to test and now it's not working fine. I've yet to take it back to my house to test there again but we are getting no signal on the DP cables or HDMI (I have no DVI to test with). If anyone can help me troubleshoot this I'd really appreciate it.

Are you sure the machine is actually booting up? What makes you think it was the GPU? Did you check to make sure the PCI-E cable didn't come lose from the GPU?

If possible I would also try another PSU if you have one around you can test on it.

So you've replaced the GPU , it was working fine and now you are not getting a signal to any monitors.. strange. Make sure all of the obvious things, ie cables are plugged into the video card not the motherboard, monitor input set correctly, cables are fine etc. After that try resetting the BIOS by unplugging power and popping out that little watch battery for about a minute. If that doesn't do anything and your computer boots but shows no display. I'd test the video card in another computer (huge pain in the neck I know) to see if it actually works. If it does work, I would suspect the motherboard might be faulty.

You might want to get an electrician to check the power coming from the wall, could be bad voltage maybe? like of there are too many things on that circuit and its not getting all the power it needs. (thats a long shot, but if nothing else works there, but it works at your place, could be worth looking into.)
