Gigabyte Z87X-UD3H Boot Loop

post #1 of 15
Thread Starter 
Hey everyone.

Today I went out and decided to upgrade my i7-930 to something a bit more modern; an i5-4670K. So I went out and picked one up, along with this fancy new board.

After installing the board and plugging everything back in, I booted it up only to find that it gets caught in a loop. The BIOS logo displays, then it goes to the blinking cursor for several seconds before the system restatrts, the BIOS logo comes back (thought disappears much quicker), and it goes back to the blinking cursor only to keep doing that ad infinitum.

After switching some things out, I found that what causes the problem is my main boot drive. When it isn't plugged in, the system will tell me to plug a boot drive in or restart. When it is, the above happens. I've tried different ports, but it does it no matter where it's plugged in. I even experimented with taking the RAM out, but to no avail.

The drive in question is a 1TB WD Blue drive with my Windows 7 Ultimate x64 installation on it. The other SATA devices I have (DVD drive, SSD, and 1.5TB WD Green) are recognized by the BIOS, but they don't have an OS installed to them so they aren't much good to me at the moment!

I'm going to attempt to install another copy of windows to the SSD, in hopes that I can at least use the computer, but until then, what could be causing this strange problem? The hard drive worked perfectly mere hours before I installed the Z87X, so I can rule that out, and the motherboard works normally save for when that HDD is plugged in, so that's not the issue either.

Any and all help is appreciated.

Well, update, installing Windows on the SSD worked like a charm.

However, I've run into another problem! Randomly, my mouse and keyboard will disconnect for a second and then come back, and I have no idea what's causing it. I updated my BIOS, but that didn't seem to do much.

Alright and then the disconnecting problem stopped happening. All on it's own.

WELL ALRIGHT!

I currently am having the exact same thing happen with my PC.

i7-4770k
16 GB ram
835 Raidmax PSU

Flashed bios to F3, reinstalled windows. Updated drivers 1 by 1, reinstalled windows, updated drivers from Gigabyte website, plugged in my WD 1 TB external drive and it disconnected all my USB devices. I had to unplug/plug to get them to work again.

Anything you can think of you did that may have helped with this? I'm about to return the motherboard, but don't even really know if that's the issue.

Anytime u get a Giga..It's like buying a ticket on the bootloop-go-round! weirdsmiley.gif
Although z87x-OC is pretty good! thumb.gif
It could be it doesn't know how to train your RAM..try some different RAM if you can. smile.gif

GBT Z87 should not boot loop, if it does then enable the single BIOS switch and flash each BIOS individually, if it still does it something is very wrong. But i guess you solved your own issue, honestly you should assume that if you skip 3 uArchs and goto a totally new chipset, then you will have to re-install windows just for the best compatibility. if you still get those USB disconnection issues then try messing with xHCI settings, change it from Smart Auto to Enabled, or disabled. But don't mess with it unless you get that issue again.

Don't mean to hijack this thread or bump necro threads, but I misread OPs post.

I'm having an issue where my keyboard/mouse/usb headset/external usb HDD are all disconnecting/connecting randomly.

Reading up on other forums, I'm not the only person who's having this issue with the z87 gigabyte boards.. Logitech 510 keyboard, mx518 mouse, plantronic 626 usb headset, and WD 1 TB Passport HDD.

try to set the xHCI to enabled, if that doesn't work try Disabled and see if that solves it. Post back.

Hey guys, thanks for the advice. The xHCI was set to enabled and the other one eHCI(? not sure) was disabled. I also should mention I did a clean install, haven't noticed keyboard/mouse disappearing/flickering (the g510 lights use to do this), but will keep an eye on it. I also read that increasing the USB voltage to 1.5v forced instead of auto... Hopefully this helps someone else who also was having this problem, but I'll def post back in a few days with how things are going.

Also Sin, I noticed you're a big poster here. Thanks for that. And you're about a few towns over from Falls Church.. Hah.
