So its only happened recently in the past month i would guess that my games start to briefly freeze up for about 15 seconds, now i looked a MSI Afterburner and at the time of the freeze the Power Usage dropped from like 85% to 30% then back to 85% when the freezing stops, my temps on my GPU are 80 - 83 degrees Celsius so thats normal, second GPU is fine no idea what is causing it, only settings ive changed is prefer maximum performance in the 3d settings, enabled sli and g-sync on windowed and fullscreen.

As for the Overclocking failed, that would be the CPU as its the only thing overclocked in my machine, to be honest ive only had this show once at start up before today which it happened 3 times in a row.

Any Help would be greatly appreciated.

I've got the Rampage IVE and I get the same issues you're having. I can't qork out what's causing it, but I think that it might be something to do with extra SATA devices. Try disconnecting everything but the boot drive.

This is a shot in the dark, but I'm hoping if between us we try enough things we could come up with a solution

Hey sorry i haven't replied in a while been working like mad recently. I've tried just using my M.2 and having the other 2 SSD's unplugged but no luck there, i had an idea that it may be a bottleneck with the Overclocking on the CPU and the 2 GPUs running but with a 1000W PSU it should be grand.

Have you got your 4 pin CPU power plugged in in addition to the 8 pin? I forgot to plug both in when doing a rebuild and the problem seems to have gone away (touch wood)

I'll have a look at it and check i hope it works, ill reply when ive checked

so i checked the motherboard and there is an empty 4 pin on it not plugged in , i only have one wire that could connect it which has 2 4 pin heads on it with CP on one and U1 on the other, i have no idea what plugging it in would do so i havent done so

That's the one you need

That cable says CPU1 and would usually be the 8 pin, but in this case your board supports both an 8 pin and a 4 pin at the same time.

Ah ok i see so it doesnt matter which head is plugged in i guess? I would assume all it would do it provide a better power balance ?

That's right - provides extra power for overclocking.

If it fits then it's the correct one

So i went ahead and plugged in the 4 pin cable and to be honest i do believe it has helped with the graphical issue and more than likely that overclocking has failed issue, but now i have a problem entirely different to that but is not caused by the 4 pin connection as it was happening before.

Basically when i bought the pc the boot up was asus logo then its swirling loading icon and straight to the desktop but now recently and i have no idea why it starts you get the asus logo then a black screen with too blinking underscores first in the top left then it drops horizontally a bit and blinks then after all that moves to the windows logo and starts loading which ive never had before and about 70% of the time the computer freezes during the screen with the blinking underscores if you know anything that can fix this im all ears.

Not too sure about that problem, but try looking in the BIOS boot screen and seeing if there's any settings that don't look right over there. Things like full screen logo etc.

Also, there's a Slow_Mode switch on your motherboard (I think near the start button?), try putting boot into slow mode and seeing if the issue continues.

If that doesn't work, unplug all USB devices and see if its the initialisation of those that's causing the BIOS to hang.

Finally, try flashing to latest BIOS?

The Logo was set on auto so i put it on Full screen now which has stopped the freezing but i am wondering should i disabled the CSM? its currently enabled and going through UEFI and Legacy option

so i went ahead and disabled the CSM and it seems to have gone back to the way it was meant to be i have no clue why it was enabled seeing im not going to be installing old legacy OS's lol

So everything seems to be ok now i hope nothing else goes wrong so i appreciate all the help dude
