Gainward GTX 750Ti video card doesn't work in 1 of 3 PCs

Hi guys,

I have 3 virtually identical PC's and just bought 3 new Gainward GTX 750Ti video cards for them.

The problem is that the new card type doesn't work in one of the PC's and all I get is a black screen from start up.

The PC with the problem was running a Gigabyte M61pme-S2 video card before which still works fine in that PC and the onboard video also works fine so there's something about the new card and that machine that is a problem, even though that combination is fine in the other identical PC's.

Things I've tried so far:

-I've tried the same card in other PC's and it works fine.
-I've tried putting a higher voltage PSU in the machine with the problem.
-I've tried removing the BIOS battery for a minute to reset the BIOS and also selected default factory settings
-I've tried a new video cable and new monitor
-I've tried running through all cables out of the card ie. HDMI, standard etc

I'm not sure what else to try.

Can't be a driver problem because it doesn't get to that stage.

Can someone please offer some advice on what the problem is as I doubt I can get a refund on a card that will test as working.

Many thanks,

Ana

All 3 on the 750's don't work in that PC?

Since the one card doesn't work on said PC does the other cards work in it?

If so then put the card in other PC and use other card in said PC.

And they all work right?
