when I try to turn my PC on, the fans start working as usual, and my keyboard and mouse lights turn on but the monitor doesn't.
Then, the light next to the startup button starts blinking white three times.
Then a moment later it turns off entirely.
I've tried to 'Power Reset' my PC and it doesn't do anything.
I've tried to open up the thing where you press 'esc' multiple times, but then the PC beeps and my monitor stays black. so no luck there either.
It's a HP Z2 G9 TWR i914900K 32GB/1TB PC
