AMD Drivers fail

[Kinetic915]

So I slightly upgraded my rig and put all my cards vertically for better airflow.  It was working great 3 7950s 1 7790 with 2 fans.  I added a third fan then suddnely the motherboard would not detect.  switched to onboard.  got the motherboard to detect but now in windows it says the amd drivers are not installed or not working.  I removed and reinstalled drivers to no avail.

Any assistance?  Thanks!

I am using unpowered risers for 2 of the 7950s.  could it be that?

It shouldn't be the risers.  Unless the risers have molex attached do them but you don't have the molex plugged in.

Yeah i am so confused now. one of those days.  Both z77 extreme 6 rigs failed..... one giving me a bootbcd error the other now hanging at a7 or a2 scusi enable and ide detect.  Dont have an ide drive connected.  giving up for today.

now its giving me a continous d7 input error with the card directly in the x16 slot.  Looks like the slots are blown. Great.

[Kinetic915]

could unpowered risers cause what happened?  mobo 2 keeps giving me no gfx detected now while mobo 1 is fine.  Definitely a problem with the motherboard.  Would unplugging and plugging in risers on the x16 slots cause loss of connectivity?  I wouldn't expect the whole mobo to be shot from some unpowered risers.... idk any help is appreciated.

Any decent way to test the x16 slots?

Take out all cards with the exception of one.  Try that in each of the slots.

tried with the first slot will try now with all thanks!

Couldn't hurt to use the "AMD driver uninstall tool" [available for only Windows 7] to completely clean out your drivers, and then reinstall them.

AMD drivers have tendency to critically mess up and then not uninstall correctly.

Though yes, your problem does sound to be more likely a hardware issue .

Yep I did do that. It's definitely a hardware issue. Idk if I blew it out with 3 7950s on unpowered risers and 1 7790 on x1 powered. Very confused

After you test out the slots individually then you try each card out separately.

once I get back from work I will do them sequentially.  I tested slot 1 and 3 but not 2.  Neither worked.

If the slots are ruined, it looks like an RMA is in order.  You may want to try clearing the CMOS, maybe some settings got messed up in the BIOS that disables the slots.  It's a long shot, but who knows.

Do you have enough power for all that?

Gotcha.  Yeah I've been clearing it with the same error.    Thanks for the help though.

I have a 1200 watt psu, which worked the entire day on the 20th

do you think thats enough power?

Finally got around to checking every slot with 2 different working cards. Input error Everytime oh well
