Monitor not detecting new graphics card, old one works fine

royngraham · Nov 10, 2015

Hey all,

Recently bought an MSI R7 370 graphics card and a power supply unit to go with it. I installed the psu with no trouble, but the monitor isn't getting a signal from the card, whether I'm using the HDMI port or the DVI one.

It's all lit up and spinning, so I know it's receiving power. I've swapped it out with the old graphics card, which still works fine, and installed all the appropriate drivers. I've tried re-seating it, to no avail. I'm thinking it must just be the card.

Haven't been able to access BIOS with the card installed, since my mobo video stopped working a while ago.

Any help would be appreciated. Thank you kindly!

You sure you plugged the additional pins of the GPU (4pin-8pin connector)? Your older gpu probably is using less power and requires no additional pins so you might have forgotten?

Okay

Well when I had a r9 270 dual x sapphire and upgraded my motherboard so I could have an i5 the screen would not pick up the card unless I went into the bios, chipset settings and then changed PCIE GEN TYPE from AUTO to PCIE 2.

But as your on-board graphics isn't working you may need to put you old GPU in then go bios and do what I mentioned in the first paragraph. Then take your old card out and put your new one in and not forgetting the PCIE power cables if it requires them.

I now have a MSI GTX 970 and I have put it to gen 3 and all is fine so it was just the r9 270 have a wonky PCIE GEN 3.
Also you loose no performance from different gen types, the different gens are the amount of bandwidth allowed for data.

Hope this helps

Hey all, thanks for the responses,

As far as I can tell the card only needs a 6 pin power connection. That's also what the website says, so I'm going to assume that's true.

I went into BIOS but didn't have a chipset tab for some reason. So I'm not sure how to address that problem.

I recently tried replacing the card entirely, but the new card has the same problem. Help direly needed!

Ok you need to flash your bios to an older version. Do you have an option for a version restore in bios? You need to do that.

Gingerbread :

My bios doesn't have that option unfortunately.

There must be a way to flash to an older version, somewhere. You probably need to either update or downgrade the bios.

What motherboard do you even have??? As from what your telling us is seems like quite a shoddy one with all these settings missing.
