Hey, so I was using my desktop last night and it worked perfectly fine. The only thing I did was swap out one of my HDD’s. now even with the Original HDD that was in there, my BIOS doesn’t see anything but the CPU. I’ve reslotted and tested to see if the RAM was working (which it is) I don’t get any beep codes except for the single POST beep. Going to try removing my CMOS and seeing if it was a setting I messed with. I can’t really think of anything else it could be.., anyone else know?
