Graphics card causing hard drive error?

[JJ83]

Hello!

I am trying to install an asus r9 270x graphics card, but when I try to boot up, I get "a bootable device not been detected" error - my hard drive isn't detected in the BIOS. When I switch back to my old graphics card, my pc boots to Windows as normal, so the problem is definitely being caused by the new graphics card.

I have a 750W PSU so I don't -think- it's a problem of not having enough power.

I have:

Motherboard: Intel DP55WB
Processor: Intel i5 750 Quad 2.66GHz
4GB DDR3 RAM
HDD: 1TB
PSU: Winpower atx-750 (I have also tried with a corsair CX500 - same problem)

I thought maybe because the new card is physically much bigger than my old one, it might be knocking a connection somewhere I didn't see, but the SATA cable seems fine and I'm not sure what else to look at.

I would be grateful for suggestions, I'm out of ideas (not that I have many to begin with!)

Can you connect the GPU to another PCI e slot to test?

Sounds like an I/o conflict.

Try this. I came across it while researching your problem.

As per troubleshooting steps, please try this:

Clear the CMOS by removing all components from the board (power supply, battery, hdds) for about 20-30 minutes and then reconnect them again.

or just pull the power plug and the cmos battery if you have one

what was you previous card that it worked fine with

Hi, thanks for the replies. I tried unplugging power supply and CMOS battery - no difference. My previous card was a Radeon HD5770 (by powercolor - not sure of other details).

I also tried checking the boot order (someone else had posted this as a solution when they had this problem), but it's set to go to my hard drive first, so I don't think that's the problem.

Looks like I only have one PCI-e slot unfortunately, so I can't check that.

 

[cowboydude99]

This is very strange. Is it possible that when you're installing the new GPU you're hitting something?

There should be no reason a PCI-E card affects your SATA ports.

I could see accidentally disconnecting the SATA cable from the motherboard side, or maybe the new GPU hits the cable and loosens the HDD's sata side...?

 

[JJ83]

I don't think so - I've tried a different SATA cable and attaching it to a different port on the motherboard which is well away from the graphics card - the card isn't touching the cable at all (this setup works fine with my old card) but still the same problem. It doesn't look like it's hitting anything else that I can see. So confusing!

 

[cowboydude99]

I really have no idea. I would return/exchange the GPU for another one.

 

[JJ83]

Thanks for taking the time to help - I will send an email to the shop and see if they will send me another one. Would like to test it out in someone else's computer first but I don't think I know anyone else who has a desktop any more!

It sounds like you southbridge is having problems on the motherboard. Do you have any chance of returning to motherboard for another/different
one?
i got this from the following form, a bad mobo is the only thing that makes scene to me

Turns out I needed to upgrade my BIOS - it now boots with the new card and finds windows - I can hear it boot up in the background, but unfortunately I just get an error of "0_" on the screen.

Looks like the same problem as here:

Hopefully one of those solutions will work for me (and hopefully not the "buy a new motherboard one" because that's a bit above my skill level I think!)

Edited to ask - how can I find out if a card is compatible with my motherboard? I did a search and found a few websites that said this combo was ok, but obviously not. I can't seem to find anything, but I might not be searching right. This person:

had the same problem I now have with a Diamond r9 270x but fixed it with a Sapphire r9 270x. I really didn't know there was such a difference :/ I can maybe return it and get a different one but I'm not sure now how to know which to get.

So I exchanged my Asus for a Sapphire r9 270x - installed first time with no problems. Hope this helps anyone else with my weird, highly specific problem!
