2700k posting error 64 slow boot

csrogue · 22 Jan 2016 at 11:49

Weird problem with mu build, its overclocked at 4.6 and has been stable for a couple of years, now all of a sudden it takes 8 minutes to pass the bios before booting normally. Motherboard shows code 64. Somthing to do with "CPU DXE initialization is started".

Anyone have any ideas what would cause this or is it a case of stripping it all down and testing again?

Any help appreciated.

try booting at stock settings.
problem could be a few things but as you have been running on oc for a few years i would think it may be down to that.

Sorry my bad should have been more descriptive. I've reset the settings to stock and still getting about an 8 minute delay before bios posts. Once booted up the pc runs fine, just a pain if i need to restart.

Im not sure if its something connected thats not initializing or if its an internal cpu error.

Full specs of pc , with motherboard model number and ram you are using.

Also try pulling out all your SATA cables from the motherboard, so no drives are attached and start the system up. Check to see how long it takes to state no boot device.

Maximus extreme iv-z
i7 2700k (stock was 4.6)
16gb geil ddr3 ram clocked at 1600
SSD

I'll strip all the drives off tonight and swap it down to 2 sticks of ram and see what happens.

Try unpluging all usb devices and add one at a time .

Excellent, weirdly it turned out to be my printer, the missus had stuck in a sd card with photos and for some reason this stopped the pc from getting to bios post.

Would never have suspected a USB device to cause grief like this before bios post.

Thank you for the advice now back and working. My only problem now is my desperation to buy new bits anyway after all the looking this afternoon.

You deserve an upgrade after all that investigation and it was her fault after all. lol

Nice one

thought it was storage related, I have seen systems hang that way before and turned out to be a bad SATA/SAS/SCSI/PATA/ connection or drive that is on the way out causing it to hang. Of course USB storage devices now cause the same issues as you realised, I would check your boot sequence in the BIOS too, it may look for USB devices on startup first, set it to the boot drive as the first one it looks for then turn off all the others in the boot sequence, that way it will never try to boot of them. Also that error you got sometimes can be memory related and reseating the memory 2/1 slots at a time and starting up with 2/1 in only then next 2/4 if you have 4 sticks will resolve that error if your sticks are good.

Good to hear you are up and running again.
