Windows 7: BSOD with Dual GFX cards, fine with single

BSOD with Dual GFX cards, fine with single

This is a strange one and i'm hoping someone can help me solve this!

I have a work PC with XP on with 2 x Nvidia 7300 GS graphics cards in. The system doesn't have an onboard graphics card and i've only got 2 so i can have dual monitors.

I tried to install Windows 7 Pro (32) on a seperate partition and it kept BSOD (hardware error 000124) on the 2nd reboot before finialising installation. The only way i've found of not making it BSOD (or just go to a black screen then restart) is to pull out one of the graphics cards and run it solo. With this done everything seems to work.

It will also happily boot into Safe Mode with both. I've got the latest NVidia driver from the site and it's been installed but that makes no difference to the issue.

Any ideas or should i just get 2 new gfx cards?

craigeve, welcome to the forums.

For the stop 0x124 in almost all cases it is a hardware problem,

which in your case seems to be fixed by pulling one of the cards.

As for using two cards for dual monitors, why? Unless you have an oddball video card, it should have two ports (if not three; a combination of DVI, VGA and/or svideo; and if three, only two of them can be active at one time).

Yeah, i've just looked at them now and realised they both have 2 outputs on them!

I think it was because the monitors i was using didn't have DV on them when i got the cards but i've changed them and now they do.

Will give it a reinstall with just the 1 in and see what happens!

So i've wiped everything, taken a graphics card out and then re-installed. Seems fine running the dual monitors from the one rather than two.

So having 2 graphics cards seems a bit of a no no, which is odd as they're exactly the same card in different PCI-E slots.

Anyone want to buy a gfx card

Try using SLI and just plugging into one card?
