Black screen after a MSI bios update

[Cleowill]

Hello, everyone. I know this is a recurring problem, I've read multiple threads on the subject but nothing seems to help.

I've recently started my first build, with these components:
- MSI B150 Gaming M3
- Intel Core i3-6100
- SSD SP550 120Gb
- Hyper 212 EVO
- HyperX DDR4 (2133) 2x4 Gb
- Seasonic S12II 520W

And a GTX 960 that I have not yet put into the case.

Everything was fine, I could access the bios but somehow could not install Windows 7 from a CD. I had read somewhere that perhaps I should update the bios, so I did. (from version B6 to B9, downloaded from the MSI website).

After reaching 100%, the computer turned off, then turned back on but the screen was black. Everything else was working (motherboard is up, fans are turning, mouse and keyboard are lit). I had wait around 30 minutes before turning it off and on again, but same result.

I've tried a CMOS reset twice (with the jumpers and the battery), I unplugged the DVD and SSD, I tried with the USB flash drive plugged and unplugged, but nothing changed. Note that sometimes, the pc would turn on for a second before turning off and turning back on again.

Does anyone have any suggestion? Thank you in advance.

Most likely the BIOS flashing failed for some reason, leaving you with corrupted BIOS file. You should follow the instructions by MSI for this situation:

I have tried this, but it didn't work.
This may be a silly question, but when doing this, should I use the new BIOS (version B9) or the one I had before (version B6)?

It is a very good question, in fact. Use the older one, not new.

I have just tried and it there is no change.

Tough luck. Your only option at this point is to contact MSI regarding this issue.

Well, I feel silly. (Yet relieved)
At some point while I was trying different things, I had clicked on the screen's power button, just in case that might have been the issue. It wasn't. But I didn't click on it again until hours later - and then it worked. (And the version is updated to B9)
So I assumed that something that I've tried in-between actually did work but I just couldn't see that it did.
Thanks a lot for your help, your solution may have just been what worked!

Glad it worked, and thank you for reporting back! 😉
