First time posting. I'm having trouble with my newly built PC. The problem is that whenever I turn on my PC, the monitor gets no signal; it doesn't even do anything (doesn't even turn on). It cant be the monitor because I switch the VGA cable from my old PC which the monitor works fine until I switch it over to the new PC.
Everything works fine when I boot my PC up; all fans spin up, lights go up. However, my motherboard beeps twice. One short, few seconds later, a longer beep. I'm not sure if this is the case of the problem, but I'm using a ASUS Z877 LE LGA 1155 along with a Radeon HD 7850. For PSU, i'm using a 550w. The monitor is a HP W22.
Not sure what the problem is, but any help will be greatly appreciated!
