I have an Asus Z97-a (USB 3.1 version) and it has some weird issues. 

 

upon a cold startup it will freeze on the Asus logo screen. it just won't move on past it unless I restart. it used to not happen that often but now its every single cold start. 

 

also when windows boots up to the login screen, my keyboard and mouse won't respond. the whole computer wont respond to anything for about 15 seconds.. then the backlights on my mouse and keyboard flash off then on again like they've just been turned on, then everyhting works fine. this hasn't happened until recently.

 

I'm assuming I need a Bios update to fix it but I have no Idea how. can somebody explain to me in super easy steps please? on the Asus website its just so confusing. any other suggestions on whats going on?

I just had something very similar to that happen. It ended up being a fried mobo, exact same model you have...and a fried PSU and CPU...but I think mine traced back to a faulty PSU. First, check and make sure you're actually on BIOS 2801. I personally don't think it's a BIOS issue at all and suspect something else is going on, but there are others here far more advanced and better able to help you diagnose a hardware problem than I am. I'm only here because I just replaced my PSU, mobo and processor courtesy of a PSU that went really bad really fast.

 

If you do wind up updating BIOS, it's pretty straightforward on that mobo. Grab an 8GB USB thumb drive and format it, then go here, choose your operating system and download BIOS revision 2801. Unzip the file and rename it Z97AU31.CAP and move it to your thumb drive.

 

Once that's done, power down, plug in your USB stick and boot into BIOS. Hit F7 to enter advanced mode, then go over to the Tool tab and select the EZ Flash 2 utility. Choose your drive, choose the file, flash away. It'll take a few minutes to flash, then reboot on its own. Don't power down while the new BIOS is flashing or bad things will happen. Like I said, though, I think this goes much deeper than BIOS into hardware instability.

I enjoy buying junk and sinking more money than it's worth into it to make it less junk.

thank you. i'll try that out and if it keeps happening i'll call Asus. it sounds like your PSU killed your system though. I have a Corsair RM series so i doubt it. hmm I hope this will fix it.

Yeah, it's a long brutal story, but I'm 99.92% sure that my (nice!) PSU went bad and zapped ALL the things. Try BIOS, and hopefully hardware experts will chime in on what else might be going on.

Okay its all updated. and everything seems instantly fixed. so hopefully it stays that way:) 

 

by the way renaming that file made it not recognize, so it just started automatic repair and finally booted from my SSD. so I left the name normal and it worked just fine. but thank you so much:)

Huh, that's weird. I had to change the name of the file to get it to read in EZ Flash. Glad it seems to have worked out for you. :)
