CPU was restarting and looks like it was fixed with a bios reset. The card has been working fine since I bought it a year or so ago. I took it out to troubleshoot the restarting issue and handled, stored, uninstall and reinstall it properly during this time. I am looking at it now and it lights up, fans spin, but the computer does not recognize it.

It is a RX480 MSI Gaming X. I tried to go into device manager and scan, but nothing. Tried to open Radeon settings and it says no hardware found so I tried to reinstall drivers, but it cancels before you are done because of no hardware found. Right now I'm on the same machine with one HDMI going from the MB into my display. When I plug another HDMI in from the GPU to display the display pops up and says do you want to swap to this display, new device found. Same type of thing every TV does when you plug something in so somewhere it's being recognized. I switch to the input, but nothing. Even if I go to my input list on my TV it shows HDMI 3 (the GPU) as an option to select, if nothing is there it is always grayed out.

Trying to think of anything I might be missing short of trying a different GPU in the same computer and vice versa. Sucks to fix one issue and have another one when putting the computer back together. Oh and I did make sure the BIOS was allowing PCIe for the display.

What is the motherboard? Try another PCI Express x 16 slot if you have one. As far as updating the BIOS, try breadboarding the motherboard. If it is stable then, try updating the BIOS that way. If you have the option of integrated graphics, try that as well using the motherboard video outputs.

yeah first thing i did was check device manager and it only shows the onboard video, no gpu. i can't update the driver because it does not read the gpu. if you try to install drivers and the system does not recognize a gpu then it cancel during the install process. i stated that i checked device manager and tried to install drivers in the initial post.

took it out several times to reseat it, cleaned everything really well. i'm looking at it right now, MSI lights on fan is spinning, it's connected to the power, but refuses to show up in the system.

I had a situation like that once. I tried everything. I ended up updating the BIOS (more or less as a last alternative) , but it worked.

i'll take a look and see if i can find an update for this one. if it fits i'm going to try swapping into another system now and my older card into this one. i really don't know what result i want. if it prove to be messed up i have to send it off to msi and if it works then there is still a mystery issue to resolve. neither options are ideal

Swapped my previous 270x into the system where the 480 was not working and it's the exact same problem. I know for sure the 270x works because I just used that system to fix another issue. Think this only leaves bios update or bad motherboard / PCIe slot. Having some issues trying to get the update because the computers keeps restarting from the other issue that I thought was fixed with a bios reset. Looked good for several hours and started again.

looks like the issue was tied to windows and a fresh install will fix everything. the short version is that i was able to put another drive in with ubuntu and it booted right up with the gpu working fine. is it possible that it could still be a bios udate, but only affects windows? now that i am stable time for a fresh install and find out for 100% that the gpu is working right. I have a feeling it is, i had this funny feeling that all of this was going to end up being tied to windows and the fix would be a clean install. if only windows ran a few key games i played, i would leave them and never look back. it's such an inconsistent os.

think the issue is solved though, unless i have horrible luck and put a clean install in only to have the gpu not work, but seems unlikely. closing it out for now since i won't have time for a couple days.

not sure what model the MB is, but i know how to find it, just takes a little bit of searching. the computer is a lenovo k450e, the i5 4460 model. modified it like crazy, but kept the original motherboard and frame of the case. i found the MB model a while back and know it's online. just crazy busy with work next day or two.

As long as Windows recognizes the graphics card, that is what is important. Once it is stable, go ahead and update the graphics driver. With the driver updated, I think you will be OK.

I would look for the Motherboard ID or the make and model of the PC so you can update the BIOS if you need to.

Got it up and running, but it doesn't make sense to me. Downloaded Lenovo diagnostic that ran in the bios and everything was fine, but still would restart.

Installed 10 fresh from an older pc with legacy bios and it booted up in my system and running great when i switched it to legacy. Not sure if this is possible, but maybe switching to legacy disabled something in the bios that was forcing the constant restarts.

I'm sure that you are frustrated with this problem. I would suggest replacing the motherboard. I would suggest a modern motherboard with UEFI BIOS . I don't have a component list. But in an effort to eliminate as many possible problems, I would convert all of the drives to GPT. And I would download a Windows 10 ISO to install from. Hopefully that will solve the issue once and for all.
