Slow POST times and laggy bios
As title. Every so often, my pc will take its sweet time stuck at the UEFI logo on startup before windows loads. My BIOS is also slow to navigate with the mouse movement very erratic.

I have checked for loose cables, reset the BIOS to defaults and even tried going back to an older windows build incase 2004 was responsible.

To clarify, my pc seems to be completely normal once the OS loads, but its still bothering me that something might be wrong

The more things you have installed in the motherboard and more peripherals you have plugged in, the slower the POST. That's normal. RAM especially has a huge contribution to POST speed, to the point where 2x8GB is effectively almost twice as fast as 4x8GB.

As for laggy mouse in BIOS, that's also fairly normal. Half of the time when I use my mouse in BIOS it's like that, so I just use the arrow keys. (Gigabyte's BIOS at least is good for that, you don't need the mouse for their BIOS)

Boot into the bios with just the basics and see how it does...

PSU, Motherboard, CPU, Cooler and Fans, RAM, GPU, Keyboard, Mouse... disconnect everything else such as usb controllers, webcam, lan/wifi/bt adapters; etc... also any Drives, which for those, just disconnect their sata data cable from the drive side. If any M2 drives, remove from their slot and sit aside for now.

Your installed OS has nothing to do with how responsive the UEFI interface is, as that is on the motherboard itself.

Slow to POST or stuck there could be related to a plugged in usb device, failing drive, faulty ram...

But see if the UEFI responsiveness is cleared up after doing this, then we can move forward. What may also help is updating to the latest non-beta bios revision from the makers site for your exact model of motherboard.

I have tried posting with everything removed from the board except the keyboard and mouse and the issue persists. I also tried each ram stick individually too. The BIOS is taking almost a minute to open when I press the F2 key on bootup too (bios access key in my case). Somethng is very wrong as it was responsive and quick upto recently.

Perform a bios update flash and see if this helps.

What about everything else? Such as your ram working properly while XMP/DOCP dram profile is enabled, and overall OS stability?

the pc seems to be completely stable once the OS loads.

I have since tried disabling the UEFI logo to see the POST error codes. There are 3 of them. One refers to PCI devices, one to SATA devices and the 3rd to USB devices.

I have tried posting the board with all devices removed already and still these error codes pop up. only pci device I have is my gpu which works perfectly fine. USB devices are only the case headers but as I said, I have tried with them removed already. I have 2 ssds, a hdd and a blu ray drive connected as sata devices but once again, I have tried with all of them removed.

also tried resetting the cmos by removing the battery too. Nothing seems to resolve it

Ok, with the os drive disconnected can you make the system post and display those errors and take note of each one in what exactly each says, when that pops up you can press the PAUSE button on your KB to pause that screen. Or while paused on that screen, take a good clear picture of these errors with Camera Phone and upload it to steam artwork, or to a free site like IMGUR and share the link to the picture(s)

A PCI device error could be anything the motherboard has on board as well; such as LAN, WIFI, AUDIO, etc. Not just your physical GPU card

partial progress. I disabled legacy usb devices in the bios and it now posts quickly and enters the bios quickly. however, neither the kb or mouse will work until the OS loads and I can't navigate the bios anymore either so I'll have to remove the battery again.

3 minutes to enter the bios is not normal. nor was it when the board was new

You sure the Keyboard and Mouse are plugged into the USB 2.0 and not 3.0?

That's the only way Legacy USB will work.

yeah, the 2 dedicated usb 2s at the top of the IO shield area
