System not recognising my 280m's!

Today for the first time I cleaned out the 3 main fans of my R1 M17x at work. It's been over 6 months since owning it so it was pretty caked with dust.

I powered it on after I'd finished to check connections and all seemed fine. I had to do this on battery so the integrated graphics switched on.


Now I'm back at home and upon booting up, disabling hybrid and integrated graphics in the bios I've found that my graphics cards aren't showing up

I'm pretty sure I connected them back up properly, the golden connector points were pushed back in.

I'm just hoping now there's something I need to do to get my system to recognize them again?

 

Did you try the power button trick ( unplug everything take out battery hold down the power button for 20 sec plug everything back in power on ) if not would start there

 

I hadn't heard of that one but thanks I'll remember that in future.

Well I gave it another reboot, went into the bios and stuck Hybrid on and that seems to have woken up one of my cards.


So now in the bios it appears but it's got the yellow warning triangle of doom and this message:

'This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)'


Hoping in this case it just means I need to reinstall the drivers?

 

I'd open the system and reseat the cards and cables again.

 

geez, looks like I'm going to have to try Aikimox's suggestion. Just keeps reverting to the onboard card even though at one point it did find one of the cards thanks for the help guys, I'll reconnect the cards tomorrow at work.
