I just built my pc and it seems like everything is working, both the cases fans are on and spinning, they both have leds turned on, and the cpu cooler is also on. The optical drive also is working for sure because it will open. I dont know if the ram, gpu, or hard drive is working. Please help. I plugged in the speaker that is suppose to make beeps if you are at fault at something, i haven't heard any beeps and i have restarted my computer three times, maybe i plugged it in wrong? I dont know but nothing i try will work.
