Basically, I partitioned my C Drive (stupid I know), and the computer acted really weird, programs wouldn't work, the desktop would randomly reset, I couldn't right click. So I needed to reinstall Windows. My computer would boot up, I could login and everything, so I decided to see if a reboot would help. I shut down my PC, and when I started it back up, nothing came up. The PC starts, fans are running, lights are on, but nothing shows up on screen. I have Windows 10 installed on a USB and DVD, I have tried to boot into both, nothing. I have disconnected the C Drive, and then boot into USB, nothing (well, 6 beeps). I have spent 5 hours now trying to fix this. I have tried to boot into the BIOS using the keys that HP says to use, nothing. I reset the CMOS, still nothing. I let it run for an hour straight, nothing. I disconnected both displays and reconnected them, nothing. The monitors are not faulty, unless they both broke in the 30 seconds it took to reboot. So what do I do?
