I am sorry in advance for all of this craziness. I will try to do my best at giving a detailed timeline of what has happened and what I think to be the issue. Please feel free to reach out if I need to clarify anything.
First things first my build is below, I have an MSI A88X-G45 Motherboard. I had never encountered any issues with booting prior to this,
From last year to about 3 weeks ago, I was using an IBM Model M keyboard with a PS/2 connector. My MB supports PS/2 so I had no need for an adapter. No problems encountered.
My affinity for the Model M keyboard led me to find one that was "born" on my Birthday. I had to have it, and so I bought it and as it originally had a terminal connector incompatible with any computer, I had to have it USB modded.
1 month ago I received it with the USB mod and I plugged it in to my computer, and it worked fine.
About 3 weeks ago, I attempted to try to mess with overclocking, I didn't do anything too crazy, I used AMD Overdrive and only messed with my multipliers on stock voltage. I think I got to about 3.9 GHz before it became unstable. Immediately regretting trying to OC at all (I really have no use to overclock; I was simply "bored") I undid any changes I made, turned off my "OC Genie" and went back to Stock settings.
Shortly after, I started experiencing random BSOD's when my computer had gone to sleep and I woke it up. I attributed this to possibly damaging my MB with my OC attempts. The error I got was: "A required device isn't connected or can't be accessed". I would attempt to restart into BIOS, but it would not recognize my keyboard or me mashing my DEL key. In order to remedy this, I would switch back to my original PS/2 keyboard, which was recognized, once in BIOS I would simply save and exit and it would boot normally. I went back to using the PS/2 keyboard, thinking that I had USB hardware issues.
I was notified that a BIOS update came out and was ready for me to install about 2 weeks ago. I updated my BIOS and decided to go look to see what was new. While in there, I found that Legacy USB was "Enabled". I set this option to "Disabled" curious to see what it would do in regards to the USB Model M keyboard.
Lo and behold, I was able to boot with no problem on the USB Model M after changing this setting. I experienced no problems since then. Because I had assumed this was resolved, I have since sold the PS/2 keyboard (I have another Model M awaiting restoration and will be keeping that one on the original PS/2 connection; will not be USB modding this one).
Yesterday, since establishing my system was stable, I decided to enable my fast boot option. I shut down my computer last night, everything was fine.
This morning, I turn on my computer for work and my POST emits 2 long beeps and a Blue Screen with the same message as before: "A required device isn't connected or can't be accessed." It wasn't recognizing the Model M USB keyboard again. This time, I had no PS/2 keyboard to use to get it to boot, so I had to go to the office.
When my boyfriend woke up, I told him what was going on (but not in this much detail). He decided to start troubleshooting and the first thing he did was swap out the Model M keyboard with a new keyboard (Razer or something) from this millennium. It booted just fine. He disabled fast boot, shut down the computer, plugged in the Model M keyboard and it booted fine. Fast boot prevented the computer from booting with the Model M plugged in.
Now, my question is this:
Why?
