good day

I have a problem when running the BIOS to display can see the code 5b.
I have turned on in the BIOS raid on the port and configuring the Intel RAID0. Involved in the raid 2 SSDs Intel 520 240GB and installed Win7 Ultimate 64bit. After the first installation everything was fine but after a prolonged shutdown the PC does not have / display code to display 5b / and not to enter the BIOS or by pressing the button on the board.

my hardware
intel dx79sr
intel core i7 3820
Gigabyte GTX670 4Gb
Corsaut 32 gigabytes 1866MHz CL9
Seasonic SS-860XP 860 watts platinum
Intel SSD 520 240 gigabytes

All this is in your manual.

5a or 5b would be something on your peripheral buses. Start disconnecting things until you find the bad part. I would start with the SSD's since they tend to just suddenly stop working like that.

That's what I try I disconnected the SSD and to the Marvell controller I joined wg disk caviar black 2 gigabytes but nothing changes still writes to display 5b. this error writes Even though all sata ports empty

0x50 – 0x5F I/O Buses: PCI, USB, ATA etc. 0x5F is an unrecoverable error. Start with PCI.

Start removing other items including the WD drives. You dont care if it boots up, you need to find the failed device causing the issue which could be the motherbd once you have removed everything but the cpu and ram. You might want to make that your next test. Try booting up with nothing but cpu and ram. Disconnect ann front usb,audio, firewire connections. If you dont get passed that 5b then it looks like its the motherbd or something on the case shorting out to the bottomside of your motherbd.
