Slow Gigabyte mobo will not let me update the bios

I'm having trouble with the Gigabyte GA-Z97X-UD3H rev 1.0 motherboard. Startup times are super slow: about 2 minutes, which is absurd for a modern computer system with an i7 4690K cpu.

So, assuming the bios needed an update (it has version F5 out of the box), I wanted to flash a new bios version. But the mobo does not let me!

The Qflash utility in the bios does not recognize any drive connected (I have 2 SSD's, a traditional harddrive, and an external usb thumbdrive connected...). It does not matter wether I start it using the advanced setting bios screen, press F8 in the traditioneel screen or press END during reset. Setting the USB thumb drive to emulate a Floppy in the bios did not help either. Qflash just doesn't recognize anything and therefore is useless.

So next, I installed the Qbios utility in Windows 7 and disabled hyperthreading in the bios, like recommended on the Gigabyte site. But every time I start the Qbios application, it gives me a blue screen of death: SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION.
I have tested the memory with memtest, and it is okay. Only the Qbios utility gives me this BSOD. So that is useless as well.

Could be a bios update would not even help fixing the startup time of the system, but since I can't even try that, I am running out of options.

My systems specifications:
CPU Intel i7 4690K with a Phantek liquid cooler
Motherboard Gigabyte GA-Z97X-UD3H rev. 1.0, current bios version F5, currently using Optimal Performance default settings
16GB of Crucial DDR3 1600 ram in 2 x 8GB banks
a Coolermaster 750W PSU
an NVidea i750 ti 2GB graphics card in the PCIex8 slot (because of the large cooler on the cpu, it does not fit in the PCIex16 slot)
1 Crucial 500GB SSD
1 Kingston 128GB SSD
1 Seagate 500GB harddisk
1 Asus blueray/dvd burner
OS Windows 7 x64 Professional

Any ideas?
