I have this issue with my computer where when it boots up, the blue HP logo comes up with the "press esc for startup menu" option. When this happens, I cannot do anything. Then, whilst I wait, it starts with a short beep. Then after about 5-10 seconds another short beep. Then finally, after another 5-10 seconds, one final beep, and then the display goes black with a blinking underscore at the top left of my screen. I've tried resetting the CMOS battery, resetting the ram, hard resetting my pc and several other alternatives but I just cannot find the solution. Please help me! Furthermore, if I were to spam "f8" on startup, it leads to the computer booting into this black screen which describes all of my computer specifications, alongside the "press esc for startup menu", and then boots into windows. This process takes over 2-3 minutes and is quite stressful.
