When booting up my new X99 Deluxe, I can't get into windows, I always wind up with "machine check exception" BSOD. I tried re-installing windows, that went fine, but when it came time to boot up the OS, I still get machine check exception. All overclock settings are set to "auto" in the BIOS. Please help. Thanks.

Hi, i had this problem also, i want to know are you running with Windows 7? If so, your motherboard won't support windows 7 SP0, try using Windows 7 SP1. it's dumb how useless Asus tech supports are. Took me few weeks to figure it out.

Unfortunately I have very limited experience with overclocking and my BIOS seems to like to overclock automatically on it's "default" settings. I'm pretty sure I have been successful in setting everything to CPU and RAM factory settings (more or less manually), but I still have the same problem.

Fortunately, I have resolved this very scary problem. It was simply solved by updating the BIOS, which I would have tried much earlier if it weren't for a bad experience I had with flashing a BIOS 20 years ago.

The original BIOS version on mine was 0404, which is apparently incredibly old. In fact, on the Asus websit they call 0505 the "first release" and mysteriously they claim it is the oldest version which even supports the Haswell-E CPU's (obviously, that makes no sense, but that's what they say).

The first time I loaded up the new BIOS all my problems were completely gone. Pressing delete or F2 let me load it regardless of what USB port the keyboard was in, and when everything was set the default "auto" settings, it actually put everything to factory spec, which I had to do manually before.

Also, Windows loaded no problem. I'm using the machine to type this right now. Everything looks great.

God, that was scary.

Well, this is embarrassing, I mistakenly clicked on your question as best solution.

Anyway, yes I was running an old version of Windows 7 64-bit. I don't think that helped matters, but if you have a BIOS version as old as I did (anything older than 0505, at the least) you should most definitely upgrade it as it has all sorts of problems.

Been running the machine for quite a while now, with no apparent hardware problems.

Could you explain further friend? I am having the same problem with my Asus X99-A on its latest bios.

Basically my windows wont load when I do a cold boot.

If I shut down the power and turn it back on however, it does boot up. Very strange.

I have fast boot options disabled within windows.

I have the X99A/USB3.1 and I get the exact same issue. I upgraded to the newest BIOS 1901.

Have you been able to resolve this issue? If so, what was the solution.

Same problem!! I think it might be Asus' problem. I'm seriously considering changing a motherboard...

I first cleared the BIOS with the CMOS jumper then loaded defaults in BIOS on first boot. Then I reboot.

I am using the Hyper Kit (enabled in BIOS with Hyper Kit option) with my NVMe SSD and I disabled fast boot in BIOS and also CSM and installed in UEFI mode. I downloaded the latest NVMe drivers from intel.

I have no more issues.

Disabling Fast Boot and CSM in BIOS works perfectly for me!! Thank you so much!!
