Gigabyte GA-Z77X-D3H MB problems
- by Hans
I installed a new system last week. I've some issues with it.
The system consists of a:
Gigabyte GA-Z77X-D3H with F9 BIOS (latest)
Intel Core i5 3570K proccesor
Sapphire Radeon HD7850
2x 8GB Corsair 1600MHz memory
OCZ Vertex 2 120G SSD
Connected peripherals :
2 Samsung 940BF (1 via DVI on GFX card, 1 via an Displayport to DVI adapter)
1 Dell U2312HM monitor (displayport)
Dell USB Hub (monitor)
Wired mouse, wireless keyboard (logitech)
Logitch G25 wheel
Canon MP800 printer
Okay, my issues are the following: if I plug in 1 or more monitor at DisplayPort during boot, most of the time it won't boot properly. I get an empty message screen of UEFI: only the header GIGABYTE DUEL BIOS appears. The system reboots itself, turns on for a few seconds (no video) and then reboots again. Now it starts all over again. This repeats until I remove all displayport monitors. Windows boots, and I can use them when I replug them.
The graphics card has been running fine for a few weeks on an older system (intel Q6600).
Another issue is; if I plug in my G25 steering wheel, the UEFI BIOS is inaccessible. It either gives the same empty UEFI screen, or the BIOS screen is rendering but crashes half way (so pieces of text and graphics are missing, and it has crashed). If I remove the G25, all is fine.
To verify the graphics card is OK and the motherboard is causing these issues, I tried an NVIDIA 8800GT graphics card. This hasn't got Displayport, but it also cannot boot the BIOS with the G25 wheel plugged in.
The PC also refuses to go into or out of standby. It just hangs when going into standby, and in other occasions (when it does succesfully do so) get out of standby.
Power supply is OCZ StealthXStream 600W. Proccesor is 25 - 30C idle, ~55C stressed (Scythe Mugen 2).
I am really puzzled what can be done to resolve this. I am not really waiting for an RMA request (otherwise I will return the MB for another type), because it will likely mean I have to wait very long before I get a replacement. Anyone else with a similar experience on this board/chipset or can help me troubleshoot this?
