I have plugged in everything correctly. Everything worked fine until now. When I boot up the PC it goes to POST where the intel logo shows up and after it disappears nothing happens and there is just a zero on the right corner. I might have effed things up because my dumb little brain thought a jumper block was a decoration and removed it to try and plug in a chassis fan. Of course I realized my mistakes after I reaf the manual. I put the jumper block back but to no avail, the same thing with the zero happens. IF I try to go to the BIOS by spamming insert the PC freezes. Moving the jumper block to the password reset gets me to bios but any input on the keyboard and the PC freezes. Cannot boot to Windows, and a LED labelled as "I" in the manual is red, while H, J and K don't even light up. All other LEDs are fine. What is the main problem here? Please help me as I haven't even used this PC for a year and I don't want already to throw it in trash as it is also my first ever PC. Helllpppp!!!!
