Help! Motherboard Freeze at Splash Screen When USB Connected

[bubblegum_bill]

Ever since I built my PC I've been having an issue with my motherboard. When a USB is connected (Memory, not keyboards or mice) and I boot it up, It freezes on the Motherboard splash screen. This has stopped me leaving my USB devices connected and I cannot update the BIOS (main reason why this is an issue). My mobo is a Gigabyte P67X-UD3-B3, I know it is old but I built a (really) budget gaming PC with second hand parts

Everything else is flawless, plays games beautifully, no freezes anywhere and boots up in no time. But this problem is very annoying and needs to be fixed!
Thanks in advance, I know this mobo is pretty old now but hopefully someone can help

Cheers

Did USB work before? Or has it ever worked?

If it's been there since you built it.

This mobo has a firewire header on the mobo. You didnt plug a USB cable from the front into it did you??

Because this will fry it

USB has always worked in Windows, I had a small issue with a bad driver but now they go fine. I only have USB 3.0 on my case so I connected that to the front USB 3.0 header on the motherboard. The only issue I have is if I have a USB plugged in in any USB port (not keyboard or mouse) while I boot it up, it freezes on the motherboard splash screen. It normally takes around 10 seconds to boot into Windows normally, but I've left this on the frozen splash screen for minutes before switching it off and on again without the USB plugged in, which always goes fine.

The problem has been there ever since I built the PC, but I suppose that could also mean that it has been there in its previous owners build too?
Thanks for the quick reply btw!

It's probably trying to boot from it if it's plugged in when you try to boot into windows. Finds there's nothing on it, (to boot from), it stops

Duh, didn't think of that. Will give it a go now to see if that fixes it!

Just restarted it to have a look in the BIOS, and HDD is set as first boot priority, with USB second. Though I found a couple of settings, one called 'USB LEGACY FUNCTION' and the other called 'USB STORAGE FUNCTION'. I'm not too sure what they mean, but they're both enabled and I haven't changed them since I loaded optimized defaults. Could these settings be of any help?
