PC won't show video after wrongfully changing IDE to AHCI

[Dakath]

Hello everyone, today after I turned on my computer I remembered that I could change my new SSD to work on AHCI, but how wrong I was... After I changed it I got a fast BSOD, don't know what was written on it, and my PC restarted, after that, never posted, it's turned on, but no video.

And there's a catch, my motherboard is fairly new after my older one got zapped by a lightning, it's sort of shady 1155 mobo. It's a Brazilian brand, I'm brazillian. (Bluecase BMBH61-S there's almost no info on the internet).

I tried to clear the CMOS by removing the battery and shorting the 2-3 pins instead of 1-2, left it there for 20 minutes and nothing changed.

Already tried using the onboard graphics and nothing changed. I also unplugged my HDD and SSD so I could go straight to bios, but nothing.

And to wrap up, I tested the ram in each slot.

Disclaimer: I only found out I couldn't change the SATA mode with Windows already installed after the occurred, so I messed up. And because it's a tradition to foreigners: sorry for my bad English.

Edit: I forgot to mention it, but before everything happened I changed two options in the bios, IDE to AHCI and FastBoot from disabled to enabled, though I don't think the latter is a problem.

Fastboot may be aggravating the problem because it tries to go directly to post without going through the Bios.

Do you have a mobo mini speaker to hear the beeps?
Any Beep?
what CPU?

I have a speaker but couldn't find the slot on the mobo, I don't think there is one to be honest. It's a i3-2100

If it is a 4-pin speaker, it is normally connected in the same group of pins where power on / off, reset and hdd activity are connected. is the so-called "system panel" of 20 pins. look carefully.

Does any light come on in the mobo? Do the fans rotate?

Make sure that the pins you have shorted are the pins and not others. Make sure you have left them as they were.

Well, I actually found the 4-pin slot named SPK1. Plugged my speaker but no sound. I've never used this speaker before so it might be faulty. The jumper is in the right spot.

Yes all my fans are spinning, the case is lighted on and my mobo has no light. One thing I also forgot to mention in the original post is that after I press the power button, it turns on for 2 seconds, turn off, then after 5 seconds on again, 30 seconds later, off and on again, after this it's just always turned on.

Damn, why did I had to mess with the BIOS, hopefully I can fix this, there's not even one month that I bought this mobo.

Anyone?

The fastboot disables the keyboard and the mouse until it starts windows. This is why the bios can not enter.

You can try some methods to temporarily disable the fastboot and let the usb work from the beginning:

a) Press power-on for a couple of seconds when starting.
b) if the above method does not work you can try to disconnect from the electricity when the system is running. The next boot would be without fastboot.

The bad thing is that clear cmos should also be enough to disable the fastboot and, for what it says, it has not worked.

It is possible that with the changes made the graphic card is not properly seated or any connection with the monitor fails.

This didn't work,. But something interesting happend, before I read your last post I tried turning on only with ram, CPU and my USB drive with Windows on it, surprisingly enough, nothing happened, so I went to my living room and read what posted, went back to try and the USB had booted! The keyboard worked and everything, of course that is not useful for me, so I turned it off and on again to see if I catch it working so I can enter the bios, but no luck so far, I'm 25 minutes here, the USB booted in less than 10. At least it's a sign my motherboard didn't break somehow. I assume that the USB booted because of what you said tbh, the FastBoot temporarily disabled and booted, but now "how?" Is the question..
