Clearing CMOS

[Theseus_3gg]

Right, 

 

So I messed with the voltage on my CPU via the BIOS (as per the instructions of an intel technician) and to my shock and awe, the computer no longer works. 

 

When the power button is pressed, the computer lights up, however the peripherals do not! Furthermore, the fully functioning monitor does not detect an output.

I've checked the monitor and all my peripherals on another device, they all work.

 

It would very much appear that my messing with the CPU voltage has done one of two things;

 

Fried the CPU, although I think it is unlikely (I may be wrong)

Or

The BIOS is no longer stable. (this is my assumption).

 

For this reason, if anyone can help me reset the BIOS using some kind of hardware, preferably, but not exclusively without a jumper cap.

 

 

Thanks from London, LTT guys.

...why would any tech support person tell you to mess with voltages to "fix" something? Anyways.

Some motherboards will detect a failed overclock and reboot with default settings and force you into the BIOS at which time you could revert settings.

If not there's the 3-pin jumper. You just have to locate it on the motherboard. Move the jumper, wait a few seconds, move it back CMOS should be reset.

If that's not an option, remove the battery from the motherboard for 5 mins or so then put it back in. That will also reset CMOS.

Ok, just so you don't think I'm a complete fool, my CPU wasn't functioning at optimal speeds, he said it could have something to do with a low voltage. "Put the voltage up to the maximum" so I did. and now this happens. 

 

I don't have a jumper so I'll have to try the removing battery. Thanks for the help, mate.

I'm not exactly thinking you're a fool but I think the tech support person is. If they give out bad information it's their fault peoples equipment end up in worse condition than they started. What CPU are you using?

What motherboard?

I've got an Intel: i7 6700

and im using the MSI H170 Gaming M3 mobo

So, it looks like the CMOS clear didn't work. I'm still having the same result. Given the symptoms of the computer, do you lot have any idea what else I might be able to do to sort it out?

Unless you were getting the BSOD changing the CPU voltage would not have increased the sub-par performance. Especially maxing out the bar. Increased voltage wouldn't make the CPU clock increase. The system would just bluescreen until you bumped up the voltage a little bit, By like, 0.025V that's it. even 25 milli-volts might be too much for one step up.

 

I know the Skylake chips are sensitive to voltage so you really don't want to crank it unless you have an overclock to suit and adequate cooling. If a full CMOS reset did nothing I'd swamp the CPU out with another to see if it died. However I'm willing to bet you don't have a spare CPU laying around that fits the socket. I know the RAM is directly tied into the CPU. You can try removing a stick (Unless you only have one but I assume you have at least 2) see if that does anything but more than likely the CPU took too much power but it can't be ruled out that it might still be OK and still recoverable (optimism) unless you have a second socket 1151 board to put the CPU in. If that system doesn't boot then the CPU is definitely fried.

 

Did you say there was an issue with trying the jumper CMOS reset method?

The only issue I had with the Jumper method of things is that I don't have a jumper!

 

I do have two sticks, of RAM, you'd tell me to take one out? Ok, I'll do that. 

And just so you know, you're right, I don't have another CPU to hand. If I was to put in a new CPU, surely the BIOS would fry it just like we think it might have done this one, or does it reset the CPU settings?
