ASRock Z77 Pro3 & Radeon 7870 -> no pic

[parre]

Hello people

I posted this question to Tom's Hardware forum until I noticed ASRock have their own support forum. I got some tips but none of them worked.

My Club 3D Radeon 7870 isn't working (no pic to monitor). By integrated graphics it works fine.

I've updated Z77 Pro3's newest firmware and checked that PCI-E is working as primary buss. I changed also PCI-E Gen setting to value 1.

I've tried also with another PCI-E buss but it's still same problem. I've checked both additional power cables but it's not working.
Fan is spinning properly though.

Graphic card should work because my old PC was Asus P5QL Pro and C2D E6400 and it worked fine.

My specs:

Intel i5-3570k
ASRock Z77 Pro3
Club 3D AMD Radeon 7870 2048 MB
8192 MB DDR3 1600 MHz
Nexus NX-5000

Steps I've done after tips:

- Tried with new Corsair 600W PSU
- Cleared CMOS and took off Bios battery
- Changed memory slot
- Tried another PCI-E slot
- Taken motherboard out from chassis and built whole PC with CPU, GPU, DDR and SSD on table

It's still not working. My monitor's power led is only flashing and then it goes to power saving mode.

Any suggestions?

Try to swap RAM slots.
