Upgraded my CPU, now only one monitor is being detected..

[Kanonkongen]

I'm a complete potato when it comes to the technical stuff, so please ask any questions if I miss some important info out.

As above, have upgraded my CPU to an AMD A10-6800k with integrated graphics, don't have a GPU installed. Have been running dual monitors for the past 3 or years on my previous CPU without any problems but after swapping them out, only the primary monitor is being detected.

They both work, have tried them independently. One is connected through VGA and one is through a VGA-HDMI adapter and its the VGA-HDMI that isn't being detected. But on startup, it shows the loading/startup on both monitors clearly, and I can go into the bios settings which shows on both monitors clearly but when it gets to the windows 8 login, the 2nd monitor states "No signal, going to sleep"

Any help would be appreciated!

You are probably missing drivers for your Integrated graphics. I would recommend looking into that.

Another potato question incoming, how would I go about doing that?

After you login to Windows 8, have you tried right-clicking on the desktop and going into AMD Radeon settings or Display Settings to enable the second monitor?

Yes, it doesnt detect any 2nd monitors connected to enable.

You can download AMD Radeon Drivers here: http://support.amd.com/en-us/download/desktop?os=Windows+8.1+-+64

OK, I would download and run this:

http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

to delete all your graphics drivers, then use the link ModMonster posted to download the newest AMD Radeon Crimson drivers, and install them. This may correct it, and if it doesn't at least you have a clean starting point.

Ok done all of the above, and still doesn't detect a 2nd monitor at all, but still shows display on startup and switches off/no signal upon logging into windows..

Try pressing the Windows and P keys and click Extend, does that work?

You need one of them to be VGA and the other DVI, with no adapters.

Rogue, No nothing happened when I did that sadly.

Lakimens, Why woud it have worked for the last 3 years using a HDMI adaptor then?

If you go into Windows devices does it only show the 1 monitor?

 

[lakimens]

Because, the APU can only take one analog and one digital connection, VGA is analog and all else is digital.

Yes only the one, and wont pickup the 2nd when trying to detect new devices etc

But he is using a converter, trhe system should "see" it as digital. And he said he replaced only his APU, meaning he had an APU before and this worked fine.

I don't think the CPU will see it, because it is still VGA on the monitor.
I am not an expert on this, but I've read that it should be without adapters.
