Hey all. So my PC won't work. I thought my APU wouldn't work without a bios update so I got an older APU to put in in order to update the BIOS. After finally getting older APU, I've run into a problem. I turn the computer on and different things happen each time. Sometimes, it won't boot at all. Sometimes I get code 99 in bottom right of screen and it turns off. Sometimes, I get Mobo splash screen and it disappears after a couple of seconds. Sometimes I have a screen that's asking if I want to boot from the hard drive into Windows. I've only had this happen twice, and I selected different options each time. Both times it went to a black screen. I selected Bios setup and Windows boot manager. I also have gotten to the BIOS twice but both times it black screened a couple seconds after finally seeing it. I have no idea what's going on or if I'm doing something wrong. I know everything is connected properly. All fans are running. LEDs on keyboard light up and turn off when it black screens.
