Hello
I am having problems booting my pc, on power on it shows a black screen and it keeps rebooting itself to black screen, sometimes with the fun being noisy and the caps lock blinking.
I have tried multiple key combinations but they have failed. The furthest I have gone is once when I held ESC key and it brought up the CMOS checksum error and continued the cycle of black screen rebooting.
