Hey guys, I recently bought a new PSU and GPU to upgrade my PC so that it can run some games better anyway this is my issue

I replaced my hd 5770 with a HD radeon 7870 along with antec 520W PSU but when i plug the new GPU in and start my PC up i get a no signal on my display, I've tried everything i can possibly google and think of.

AMD Phenom II 1100T (x6) Hexa Core 3.3GHz
890 GX Extreme4 R.2– chipset - http://www.asrock.com/mb/AMD/890GX%20Extreme4/
RAM- 4,096 MB Patriot Memory DDR3 @ 533 MHz x 2.
ATI Radeon HD 5770 1GB
Antec 520W - http://www.pccasegear.com/index.php?main_page=product_i...
1TB HD – Main (Seagate Dont know exact model.
2TB HD – Off ( Seagate
Thermaltake V3 Black Edition VL8000 Series Case.

i bought this exact model GPU - http://www.pccasegear.com/index.php?main_page=product_i...

So ofc before i bought these items i looked up to see if they would work together and all reviews and thoughts pointed to YES BUT when i took my PC to the shop today to get a pro to look at it he said that my mobo wasn't compatibly with that graphics card??

I've made sure that the PCI Cables are properly attached to the graphics card, Ive also tried the Molex to PCI adapter.

taken out one ram and tested still no luck, Disabled integrated graphics then restarted

The main issue remains that when i start the PC with the New GPU no display appears on any monitor i attempt to use , Also DR DEBUG, A feature of the MOBO pops up on the LED with "97 - which refers to "console Output Devices Connect"

i'm pretty clueless right now and any help would be appreciated, I don't really wanna have to refund this product i consider being rude and quite honestly rather just buy a new GPU and leave this in storage ...

Thanks Justin!

I had the same issue, after I reseated my GPU it worked. try doing that and ensure that the power connections are secure. if that doesn't work try using onboard video and go into the BIOS and change display to PCIe

The only compatible card for win7 listed on the manufacturers website is: ATI Radeon HD 2600PRO
There are 3 cards listed for XP, which makes it look like the board was intended for XP, which is weird...
http://www.asrock.com/mb/AMD/890GX%20Extreme4%20R2.0/?c...
check the processor compatibility by model number...
you may have put a new hot shot card on an old motherboard. The bios may not run it...the board looks like it was intended for XP type technology. Which is strange but true.

Reseating? taking it off the thermal paste and putting it back together right?

@ Sound, Yeah thats another problem, Their site is WAY outdated, I used the HD 5770 Before with No problems and i've looked around and people have used this Mobo with this graphics card. Also I don't wanna use Crossfire I just one one GPU

Would reinstalling Windows with the New GPU have any sort of benefit?

Intended For XP?? When the Mobo was released it was recommended to use Win7, Its so werid why cant anything be simple anymore ill look into it!

I've starting reseating it but nothing. im pretty clueless atm and pretty depressed about this, the mobo its self isnt that old, I mean Sure 2010-11 but it does well vs todays ones,

If worst comes to worst ill just sell it for 200$ It's in working order and i can just buy another card one i'm 100% sure works and from my local store so they can plug it in etc.

Thanks!
