Hi there.

I recently purchased an ASrock z87 Extreme 4. Everything was going well until I tried to install my HD 7850 GPU. I got the 5 beeps thingy. Thinking something was wrong with my GPU, I went to check it in Asus Z68 Motherboard. It worked perfectly that time. So I assumed the PCIe slots were busted so I am going to RMA it tmr.

I was wondering, is there any way to fix this on my own? This would mean I don't have to visit my Retailer to RMA. Thanks

Specs-
i5 4670k
AsRock z87 Extreme 4
4GB RAM (I just realised two different ramsticks at different frequency (1 was 1333mhz the other was 1600mhz) so I only have 1 stick now lol)
Seasonic M12II 620w
500GB HDD
2TB HDD
MSI HD 7850
DVD Drive from Sony.

if you have another pci-e card. put it in and boot to bios. then go down to the gpu menu and make sure its on peg 1 @x16.
reboot allow a dma update and turn off. (boot into windows if that makes you feel better then shut down)
as soon as the pc is off and all residual current has washed out the system replace the old card with the new making sure theres no dings on the pci-e connector of the new card. that you have the power firmly connected... install and power on. let the pc get to the dma update and reboot another 2 times doing the same thing if it gets past the post screen...
if it doesnt get past the post.
remove the card and put it in the next pci-e down. if it works then the board has a bad pci-e slot.

Can I just use my Intel's Onboard GPU? Infact that is what is enabling me to use the computer now. I have a GTX 560, but I just want to save the hassle

seating it properly just means check the connector block to make sure its dust free. both the pci-e block and the strip on the card itself... check to see theres no corrosion or gunk stopping a connection.
place it in the slot and press firmly till you hear the click and then screw it down to the back plate of the case. give it a slight tug 1s done on both front corners and again give it a little push just to make sure... connect the power and boot the system...

dma update is basically a list of hardware addresses that is created at post so the cpu knows everything is. each time you remove or add or change hardware settings this list has to be updated.

as your 560 works it looks like your motherboard may support pci-e 2 but falls down when pci-e 3 card is used.
thing is that shouldn't be a problem as most of the time the 2 standards are interchangeable and compatible. my only other idea is that even though the psu is 620w it may not have the required amps on the pci-e 6pin connector.
you can test this by connecting a 6 pin to x2 4 pin molex connector to the 12v molex on your psu.... http://www.amazon.co.uk/iComp-Molex-Express-Graphics-Adapter/dp/B00APEKI80 looks like this (should be 1 in your box you got the gfx cards in)
but honestly thats a guess as im not sure what the amp requirments are for either of them cards... hopefully some 1 will clarify this for you...

I really hope that isn't the problem, since I bought the mobo for PCIe 3.0 (future proof) as well

Anyway ASRock has suggested decreasing the PCIe slot from gen 3 to gen 2. Ill try that

OK I got it to work finally!! You and ASRock really helped me.

I just had to decrease the speed of the PCIe as stated above and voila! It works!

Can you help me figure why this has happened? Will it happen with other PCIe 3.0 cards?

compatibility should improve over time with either bios updates for the gfx cards or the motherboard. asrock will likely issue a bios update first as it affects there boards directly...
1 thing i will add. asrock may be a cheaper end manufacturer but every time i have requested help they delivered, unlike asus who just said not our problem its the gfx card that doesnt work. this was back at the launch of pci-e 2.0 with the 8800gt's... so im glad your sorted. and even if they dont bring out a bios update any card you try that doesnt work on 3.0 will work on 2.0 with the minimum performance hit.
