I've tried the "Force PCIe Gen3" patch on my MSI BBII + 3930K but it caused a 'no signal' msg on the monitor.

Thinking my OC had something to do with it, I switched to the 2nd Bios at stock settings and set the PCIe speed to Gen3 in Bios and reset, only to be greeted with the same 'no signal' msg.

Thankfully, MSI has 3 Bios's so I'm currently on Bios C. However, to reset Bios A and B, I have to use a jumper according to the manual:


Which I don't have. So I tried with a metal tip screw-driver shorting the 2 pins but no change.

Any advice ?

When you do a bios reset you have to completely de-power the bios chip.
Since a power supply will power the bios chip even with both the computer and the power supply switched off, you also have to unplug the power supply from the wall outlet to successfully complete a reset.

Thank you for the suggestion. Yes I had the power cord still plugged in when I tried to reset the Bios.

I'll do it when I get home, but just to be clear, the metal tip screw driver is enough or do I need to find a jumper or something else?

The jumper should be there. You just move it to the other pins.



You should have a jumper on the "Keep Data" pins all the time (except when doing a reset).

And, yes, with the "Keep Data" jumper removed you can just short the "Clear Data" pins.
You only have to short them for a split second.

Cheers but there is no jumper on my mobo. Went to the shop to make sure and the new boxed boards (two BBII) had no jumpers either.

I've had this board since 03/2012 and didn't face any issues with saving/changing Bios settings.

Anyway, I did what you suggested and shorted the pins without the power cord, booted, black screen for 20 seconds then monitor comes on with the blinking cursor on the top left with black background and it stays there, blinking for hours with no activity on HDD/SSD (HDD LED doesn't even come on).

I tried pressing the 'Del' key rapidly during the 1st 20 seconds of booting when there is no signal hoping it will start with me on Bios but alas, I'm still greeted with a blinking cursor.

I have not made any change to the Bios except for PCI-e 3.0 speed and the PC works perfectly OC'ed on Bios C. But Bios A/B makes it look like I have SATA/RAM issues.

Any other ideas I could try?

Sorry, but I have to ask. Did you pull the bios battery too?
