Last night I changed vttd voltage on my mobo from1.1 to auto. So I then booted to my desktop to see its at 1.5 which I know is way out of safe limits. The computer then suddenly froze. So immediately I restarted and reset my bios. But since then my comp immediately resets when i hit the power button. Is there any chance I may have killed the CPU or mobo?
 
try loading bios hitting f7 to load optimised defaults f10 to save and see if that helps there is a section in some bios which you can tell it what to do with the power button eg turn off straight away and hold for 5 secs to reset maybe yours just got mucked up if it fixes it you can just re apply your OC
 
Can't go that far it lasts like half a sec after pressing power, cheers for the suggestion though.
 
Reset the CMOS - disconnect the power connector from the motherboard and take the CMOS battery out before bridging the reset jumper for 10 seconds.
 
I had similar once.... disconnect from power... take battery out of mainboard and leave for an hour or so then try starting it up.
 
Gonna try that now guys cheers, but I can't see a jumper on my mobo it's the asus rampage iv formula
 
According to your manual you have a clear CMOS switch on the rear panel of the motherboard, it's in-between the PS2/USB and Optical S/Dif connectors with a circular arrow on it.
 
Yea that switch isn't making any difference. Trying to look for Jumper on mobo at the mo but can't find anything. On the asus site it shows CLRTC but I can't see it on the mobo anywhere

pulling the battery and leaving it a good hour is the best way (well for me it has been atleast)

jumping the reset etc never seems to do the trick
 
Hope it works!

I got a right dressing down, in a nice way, from the rog forum a while back.

Basic sentiment was 'never buy a pro rog board and set anything to auto'. Realised I was out of my depth but luckily didnt blow my cpu while running 1.55v through it because 'AUTO' decided to.
 
Very tempted with your chip btw.

Another year and ill pick one up with a couple of nvidia 880 or whatever they will be.
 
Unplug power, pull the battery out and leave overnight. Had to do this when i shorted my board and it messed up the sata somehow but doing this fixed it
 
Pull the 24 pin cable as well. If it's still not starting up, try jumpering the 24 bit cable (by shorting the green to the black cable from behind the plug end) and plugging it back in to the motherboard.

I have to do this sometimes if my motherboard spazzes out due to too bad overclock settings.
 
Simplest way thats always worked for me. Unplug power, remove battery, PRESS YOUR POWER BUTTON (I always get a flicker of LED when I do this, its just to make sure 99% of the charge in things is gone), wait 30min go have a cup of tea, insert battery, replug computer and magically it comes to life.
 
I'm trying to figure out why you guys are leaving the system for an hour after removing the battery, why do you think you need to leave it for such a length of time?

If you're attempting to dissipate remaining charge in the motherboard, you can easily accomplish the same by just hitting the power button a few times whilst the power is switched off.
 
Did you put the clear cmos jumper back on correctly? I'm only 33 but i sometimes have an issue getting jumpers on correctly, despite the fact i can see them pretty well.

Use a flat head screwdriver to start the system up also, take the case wiring out of the loop(just something else to rule out)..

If it were me, i'd be inclined to remove the hardware from the case, find something to sit the motherboard on and attempt to boot with the absolute bare minimum, ie. CPU, 1 stick of ram and onboard GPU(should be active after clearing CMOS). I'd also use the paperclip trick on the PSU to confirm that powers on correctly, with any connectors removed from the motherboard(i'd have suggested disconnecting them reconnecting each anyway in testing).
