New Build is "double booting"

Mr Jack · 1 Dec 2015 at 18:27

When I power on my new build it seems to power up twice, the first time is briefly flickers on, then it stops again before booting up fine.

Any ideas what might be causing this?

Anyone?

Mines a completely different spec but been double booting from day 1!

Have you overclocked it or anything like that? If first boot is failing then it will reset and try again with a lower profile?

wazza300 · 3 Dec 2015 at 15:35

its usually to do with memory,memory checking

touch more memory controller voltage might help it as will latest mb bios

(no idea what the memory controller voltage is labelled as on skylake though)

Mine will 'double boot' as you call it the first time it's plugged into the mains. Once left plugged in it will just boot the once.

yeah that's normal,from a cold bootup,mine does it sometimes but not everyboot/restart

My old Gigabyte X58 board did this as well, but only on a cold boot. I *think* it's the BIOS double checking the settings. Is the system overclocked?

Same here. Sure I read it was something to do with Gigabyte boards checking something, Nothing is wrong AFAIK

Not yet. It's running on whatever the stock values are until I get a bit of free time to tune it.

I have a SM951 256GB also and I believe it is that which is causing it on my pc. It's almost like it needs to reverify the device before booting from it when using a UEFI version of windows.

I have a Samsung SM951 128GB M.2 PCI-e Gen3 also. I'm on a new build and it does this too, double boots, except sometimes it wont boot at all and it just POST loops over and over until self repair kicks in. I've never had one before so wasn't sure what the process was but mine seems to be not so healthy.

My PC used to do this, I never did bother fixing it, but the issue went away when I upgraded my motherboard.

Same here, I notice it after messing around with the insides I immediately think I've done something wrong but the second time it boots fine.

OOC i guess
but My old old pc would thro a wonky and it wouldnt boot i had to get my mate to lend me a stick of (corsair ram? ddr3) i stuck that mem in. (get into the bios save my settings, then restart, with my crapper memory, and settings)
then all was good until i got a bsod , then i would ask him for memory again
Bios can be a itch

Mine did this until a newer BIOS came out - might be the source of the problem if no overclocking has been done yet
