MSI BIOS hang - B4 code?

[Nine Iron]

My MSI board (B75 chipset) has recently starting to "hang" during the occasional boot, showing a B4 message in the corner. It usually crawls through to Windows eventually, but not every time.

Any ideas? At first I thought it might be my front USBs because they weren't working after such a boot, but it's just happened again with them disconnected from the board. Is it worth trying a BIOS update (it's dated July 2012), or is it more likely to be a hardware/peripheral issue?

Cheers,

M.

There seems to be an issue with Msi boards having this problem and no one really seems to have an answer to the problem as there are multiple threads with other people having the same issue.

BIOS update - v12 to v15 - seems to have solved the problem, touch wood.

Good lets hope it stays stable for you and fixes other peoples issues too.

B4 is the first thing my board displays on the power on tests. It's probably memory.

Luckily i saw this... i was gonna post about this one... I am using my computer for almost a year now , this problem happened to me about 2-5 times only but this month it continues to happen every after a long shutdown of the computer.

Mines different it hangs on a cut picture of msi bios and it will restart automatically and then it will boot up properly.

Note: After that happened i can shut down and and boot up again without any problem.

Any fix ?
