Hi! Im building my first pc and was hoping to get some help. I plugged everything into my motherboard, booted it up, and everything is working fine, I get beep codes that Ive tried looking up but all i can find is "no vga detected." I have an Asus A68HM-Plus with AMD Athlon X4 845 (they are compatible). What can I do to fix this? I've tried different monitors, cables, replacing ram, and no change, its the same beep code, someone please help!
