Hello, I have a Gigabyte.g1 assassin 2, heres my story

I was on the bios and decided to overclock too get a bit more performance and decided to use the 3d overclocking feature, So I raise my clock speed too 4.2 Ghz and set vcore to 1.290 v (kept bclk on auto) so I save and reboot, open core temp, cpuz all that stuff then run prime 95 temps were fine then I check Vcore the voltage was sitting at 1.260v so I decided to go back to bios and correct it while In bios the vcore shot up to 1.356 volts I loaded optimized defaults as fast as I could the saved and rebootd. Bamm bricked I get the post screen In high definiton is the only way I could put it when it's usually in a low resoloution. Can't access bios or anything nothing works then it beeps three slow times then it turns to a black screen and has a bleeping underscore while just sitting like that untill I turned it off.

continued

Ok no worries as I have a second BIOS which I loaded and everything was fine but I never flashed the bios so I thought that could be a problem. So I go to gigabyet website and yes it was the right board and revision number and downloaded F11. So I go back to my bios flash everythings going well the wouldn't you know it that get's the exact same problem as BIOS 1 with the post screen then the blinking underscore.

So what can I do guys I've already tried
Resetting CMOS
Done the power switch thing were you hold the power button the let go quickly
Re seated everything
booted with a USB flash drive with the latest bios on it to see if it would somehow update it.

Is a new motherboard on the table or what?

Thanks for the help
 
Hopefully you disconnected from the mains before resetting CMOS

Remove button cell battery for 30 minutes
Replace battery

If the bios update was correct version and succeeded previously PC may recover



If not try re flashing correct version
If internal and external graphic card
Remove gpu card
Remove any other PCI or PCI-e cards


Try again booting with correct bios file in a small USB memory stick
Under 2 GB fat 16
Use USB 2 not USB 3 port
See if this works

Best of luck

Hi mike thanks for reply.

Yes I took out power and took out the battery and left it overnight and If i take out the gpu The 3930k has no IGPU so I wont be able to see.
So should I get a new motheboard or even see If I can RMA it?
 
Hi

I expect they can detect a bricked motherboard caused by over clocking
It may be possible for specialist to re flash corrupt bios even if chip is soldered oN motherboard
They seem to be tiny serial I/ O chips nowadays
I don't know of any one but gigabyte or main dealer may how to do this
If this fails a new board will be required
