Computer hangs on BIOS splash screen on first boot only

Hey all,

I'm posting because I've run out of ideas as to why this might be happening, aside from a bad MoBo. I really hope that's not the case because it's brand new. I just build a new computer a couple weeks ago, and this started happening a couple days after I put it all together. Here are my specs:


    Gigabyte Z87X-OX MoBo
    Intel i7 4770
    G.Skill Ripjaws X 8GB 2133
    Samsung 840 Pro 256GB SSD
    Toshiba 2TB HDD 7200RPM 6.0Gb/s 64MB cache
    Cooler Master HAF 912 Case


So, let me explain the issue a little bit. In the morning when I get up and turn the computer on, it hangs at the BIOS splash screen, keyboard and mouse do not receive power. I can use the reset button on the case and it reboots perfectly! This does NOT happen every time, but it is usual. When I restart the computer nothing happens, it works perfectly.

Here is what I've done to troubleshoot so far:

    I've checked all cables I can think of for all hardware
    I've removed and re-installed the RAM
    Unplugged and replugged the case front panel cables, the HDD LED was not working
    Changed RAM multiplier in BIOS. RAM was set to 1600, I changed it to 2133
    Changed OS in BIOS to Windows 8
    Used the Samsung Magician software to set SSD to performance
    Updated all software and BIOS with Gigabyte AppCenter


I haven't reset the CMOS yet. That's pretty much the only thing I can of that's left to try.

I think it's an issue with power not getting supplied to some component during the first one, but once the computer is on for a second it works just fine and I can reset it. I'm wondering if it has to do with my mouse, keyboard, webcam, or something of that nature. I really don't want to have to RMA this motherboard and be without a computer!

Does anyone have ANY ideas whatsoever about this?

Thanks!

Do you have the latest BIOS? What's the model number of the set of DRAM? What's the PSU?

I thought I had the most recent BIOS but I did not. I just updated them about 5 minutes ago and we'll see how that works tomorrow when I turn my computer on after a long time being off. RAM model is F3-17000CL11D-8GBXL. Sorry I did not put the PSU in the post! I knew I forgot something haha. I'm using a RAIDMAX HYBRID 2 RX-730SS 730W ATX12V V2.2/ EPS12V

Let us know, if not already, may want to enable XMP with new BIOS and select Profile 1, if still no joy we may want to make a voltage adjustment or 2

After upgrading the BIOS and trying it for a couple days I don't seem to be having the issue anymore. I believe it happened one time. I also got an error that told me to reset my BIOS to Optimized Defaults because the computer failed to boot correctly. That hasn't happened again. I think I might be (fingers crossed) in good shape as of right now!


Solution: it looks like updating the BIOS from F3 to F5 solved the problem so far.

Thanks!!
