the graphics card is a radeon 5780 i believe and there is nothing wrong with it as i've tested it before, there is also nothing wrong with the motherboard as i've tested other also working graphics cards on it, i've used the pci e cable. i've also tried using safe mode to disable the onboard graphics and there doesn't seem to be any setting to enable it (if thats how it works) in the bios, this is the closest i could find to what my bios looks like

i'm not sure why i'd even have to do that because previously this system had a better hdd and i had no problem with graphics cards atall, the current hdd is older from a 32bit system, but as far as i know that doesn't matter. and its probably not worth mentioning but the cd drive is older too

it is running windows 10

edit

the motherboard is p01-a3

the graphics card has green lights on it, which means its connected properly

installing ati catalyst fails

disabling onboard graphics in safemode, turning off and putting the monitor into the dedicated graphics does nothing

dvmt mode is grayed in bios
 


This is mostly due to windows 10 having issues recognizing it. Go to the control panel like you would in windows 7 and check the device manager. Usually if all the hardware works but graphics still not detected, its some internal buggy problem with the OS. Just force detection/enable, and should work.

 


is this an option thats suppose to be in the device manager? can't find it. and i forgot to mention that this use to be a windows 7 os, i was just under the impression that upgrading to windows 10 would fix it
 


Upgrading doesn't really fix things, since when you upgrade you are essentially bringing whatever you have to a newer OS, but everything else, registries, files, all is still being kept by a windows.old folder. Unless you do a fresh install. The option is the same as it would be in windows 7. Go to device manager and look for the display adapter.
 


when i put in the older hdd the computer had to be fresh installed ofcourse, but im pretty sure when doing the fresh install the dedicated graphics card was inside, this computer originally only had integrated graphics, could this have caused a problem? and does a fresh install do anything to the bios? i had a closer look around in there the other day and found some option "power on by pci-e" but nothing seems to change

is this force detection option you're talking about mean't to be specifically in device manager>display adapters? this is a run down of everything i've done to try and find the option, i've only got my integrated graphics card in the dropdown of display adapters, right clicking display adapters and looking for hardware changes does nothing, properties just has an empty window. scanning for hardware changes on the integrated graphics does nothing, i've checked the properties of that and i know for a fact its not in general, driver or details, i've got events and resources though. am i suppose to do something with one of them?
 


Yes its force detection. And no fresh install of OS or any software doesn't do anything to the bios. If forcing the detection and whatever options you've tried does nothing, install the gpu into a different pcie slot. It could be that your pcie slot got damaged.
 


i see, unfortunately this motherboard only has 1 slot big enough for graphics cards. i'll go ahead and check to see if its damaged. odd that the lights on the graphics card are green if that is the case, they should do something about that
