One day my computer stopped recognizing my ethernet-card, tv-card, printer, and a wireless networking card. And now it just refuses to detect any of them. My graphics card, mouse, keyboard, and built-in networking works fine, so I'm able to use the computer as normal except from the features mentioned above. I have no idea why this happened, not sure what I was up to. (One thing I do know, is that I automatically assigned a driver to a device with one of those questionmarks in system devices, but not sure if that was when it happened. And i dont remember which device). I had four internet connections, one for each device, before the accident. Then i saw them all vanish, except for one. Anyone who'd care to try and help me along the way on this one? If you need any additional system info or other, please ask. My motherboard is an "asus a8n-sli premium" btw. Thank you

when i wrote "system devices", I of course meant "device manager"

I would suggest booting up in safe mode, going to the Device Manager and removing all the devices that you are having a problem with, and then reboot. Of course, also remove any devices that are indicated as having a problem. Do yourself a favor BACKUP!

you can try finding a driver for your chipset bus but should be fine when you uninstall the current devices and reboot to reload them again it is what controls your pci slots

Thanks for the quick response. Well, my problem is that the devices are not in "device manager" at all. So i can't remove them . They are all connected to the motherboard, but don't show up in device manager. Is it normal to have 2 serial ata controllers and 1 ide controller? I didn't build this pc, so I'm not sure how it's set up.

i would physically remove all of the cards from computer, then put one back in at a time in a different slot to where it was before and see if windows detects it. could be some kind of conflict? you might need to have drivers handy if windows does not automatically have drivers for those make/model devices

I read on another forum that this was a common problem for my mobo when using some kind of tv-card, but noone came up with a solution. And yes, I've tried unplugging my tv-card. Not sure if it can be fixed, but it worked with my tv-card in for some time(months), and then suddenly refused detecting all pci slots. I've got my printer up and running after some changes in bios, so I hope there is a solution out there for the rest of my mobo problems.
