Hi, So I bought a new harddrive, because my old one was too small. I removed the cables from my old one, put them in the new one and booted my pc. Result: Black screen. All the fans turn, no beeping, LED's work, I can hear my harddrive and my dvd-drive buzzing. Something to note: My G15 Display does NOT light up, which it usually does. So my keyboard appears to be powerless. I have tried removing the BIOS-battery, removing one and both RAM sticks, Disconnecting everything but the CPU, GPU and monitor. No luck. The fact that my keyboard doesn't get power suggests a faulty motherboard to me, but I could be (and hope to be) completely wrong. I tried removing my GPU, but didn't hear any beeps (the power-chord was still connected, don't know if that matters?). In short: Computer seems to boot Everything sounds like normal No beeping Unpowered keyboard No luck on BIOS reset. When I put in my new HDD, I touched the radiator, to get rid of static charges. Could it still be that a static charge ruined my MoBo or some other part? And is there a way to check if my motherboard is faulty? Greetings, Marty Edit: I have now tried putting the motherboard on a static-free surface (wood) and connecting only the cpu, gpu, and monitor. Still the same. I find it strange that my motherboard doesn't beep because there's no RAM. Another indication of a broken MoBo? Edit 2: I see now that I completely forgot to mention my specs: Motherboard: Asus M4N78-SE CPU: AMD Phenom II X3 720 BE GPU: ATI Sapphire HD 4850 Monitor: ACER 22" x223w (I believe) Edit 3: I left everything running for a minute or two, then removed my cpu cooler and touched the cpu. Turns out the cpu was real cold, like nothing happened. Isn't this a clear indication of a broken cpu?
