ASUS P8Z77-V PRO Boot Errors?

My first post on this site, community's never let me down before so I'm hoping you can help me.

I recently purchased an ASUS P8Z77-V Pro motherboard for my first ever gaming build.

I installed everything correctly. I went to boot for the first time; no luck. The LEDs on my mobo told me there was no VGA cable (which there was), then told me there was no boot device (which there also was). I checked all of my connections but still got nothing to work.

After searching through some internet forums, including this site, I found that other people had similar problems, and had resolved them by removing the graphics card and one stick of RAM, so I tried that and it booted. Fiddled around with the BIOS to see if there were any settings I could change and I even ended updated it in the end. Still nothing if I install 2 RAM sticks and a graphics card. It's now stuck in a boot loop but I'm pretty sure this is my fault to some extent.

  1. Hi, It would be helpful to detail the RAMs, graphics and power supply models.
  2. Oh yeah, sorry.

    I have two 4GB sticks of Corsair Vengeance LP DDR3. My graphics card is the ASUS GTX 660Ti. My power supply is a Novatech Powerstation 750 Black Edition.
  3. Have you connected boh PCIe cables to the graphics card? Does the system boot with one RAM and the graphics card?
  4. I connected all cables to the graphics card, and no it didn't boot if the graphics card was installed at all so I was using onboard graphics.
  5. I suggest taking the board outside the case and test again on a cardboard or similar non conducting surface. Make sure that the graphis card is proerly inserted in the PCIe slot. Test also, if possible, the graphics card in a different PC just to make sure it works.

    I tried that and it still didn't work. I tested the other graphics card in another PC and it works fine.
  7. Then it might be a CPU socket bent pins issue. You can uninstall the CPU and check the socket with a magnifying glass. When reinstalling, clean the old thermal paste and reapply a new one.
  8. Well I didn't touch any pins even slightly, I was very careful as this was my first build, but I'll check anyway.
