So, I was in a discord call when my pc suddenly blue screened, but instead of waiting for the error to be reported to microsoft the pc turned itself off, not restarting. I then turned it on again, I'd had an old pc blue screen constantly years ago and it still worked, and it went straight to the BIOS and the disk wasn't detected in any SATA port. I then turned off the pc and removed the disk, but then remembered that I could probably check the disk if I ran a live distro of Linux from a pendrive I had, so I reinstalled it on the computer - that's when trouble began - the pc when turned on started beeping three times during POST, so I turned it off and removed both the disk and the pendrive and reinserted the RAM. Then, when I turned it on, it simply lit its LEDs up but did nothing, I had even to switch it off directly on the power supply. Could anyone help with this?
