    PC turns on, No signal, keyboard/mouse.


    So I was in my bios and I changed my CPU mode offset sign from + to -, I saved the settings and exited. When the PC restarted it came on perfectly fine but I am getting no signal on my monitor and my razer keyboard & mouse aren't coming on or lighting up.

    My motherboard is a P8Z77-V LX
    My CPU is a Intel Core i5 3470 3.20Ghz.
    My RAM is G.Skill RipJawz 1866mhz 4 X 4
    My GPU: Asus GeForce 660ti DirectCU II OC Edition.

    I googled around and it said to take the battery out for 10 seconds and put it back in, I did that and no change, I also took the jumper from 1-2 and put it on 2-3 for 10 seconds then back again, Again no change.

    Ive reseated the RAM/GPU and CPU and nothing seems to be working.

    The pc turns on fine but nothing seems to be working.

    Even my Corsair H80i pump LED changed from white to pink which is the colour I set it. All fans are working too.

    If anyone is wondering why I changed my cpu offset mode, Before this issue I just had a bluescreen for WHEA_Uncorrectable_Error, I turned my PC back on and I googled around and it said it was something to do with my CPU voltage, and one person suggested to try and change it from + or auto to -, So I restarted my PC and changed the cpu offset mode from + to -, after that it doesnt seem to be working and im not quite sure why.

    Does anyone have any idea what I can do to try and solve this issue or should I just order a new motherboard?

    Thank you.

    :)

    Windows 10 keyboard and mouse not working

    I recently reset my PC and upon setup my keyboard doesnt work neither does my mouse but my keyboard shows there is signal but it also works when i enter the Bios settings.

    I use a Dell keyboard (not sure of the model) and a Logitech M280 mouse.

  3. Windows 10 bricked my Asus Desktop

    Hello. Unfortunately we can't get the computer to do anything. It won't react to the keyboard or mouse. The monitor says "no signal". Computer turns on and that's it.

    He received a message during the upgrade about Bios being updated before the reboot. Doesn't the Bios handle the interface between the computer and keyboard/mouse/monitor?

    Thanks for any additional help.

    PC turns on, No signal, keyboard/mouse.

    Have you tried loading Optimized Default in your bios?
    Also, have you tried lowering your overclock and CPU PLL?



    Keep in mind, changing offset from positive to negative can make a substantial difference, depending on your specified offset.
    Can you post the numbers for your offset, CPU PLL, CPU PTT,VCCSA

    I can't do any of that as when I turn my PC on, My monitor is just on standby mode, And the mouse and keyboard don't turn on/light up. funny thing is I can keep my PC turned on for 1 hour, fans running and everything, The monitor and mouse/keyboard just don't seem to want to come on.

    I just changed it from positive to negative, I don't know exactly what that does but after I done that I saved the settings and now im having this issue, I have tried taking the CMOS battery out multiple times to reset the bios to default hoping my monitor and keyboard/mouse would come on but its not doing it.

    Ive tried the RAM in 1 by 1, still nothing, And also with no GPU.

    Anything else I can do or would my best option to be buy a new motherboard so the BIOS is default? Then if it still doesn't work ive broke my CPU?

    Thanks alot for your time *Smile.

    I think you may have tried all of this, but thought I should post in case you missed the final stage. Take a look at the pic below. Obviously read it all (duh!), but pay particular attention to the bit I have circled as it may make a difference (otherwise why would Asus have mentioned it?). Good luck!

    Edit: And when you are trying to reboot afterwards, you should be doing so with everything disconnected. The monitor should be connected to the motherboard. The graphics card should be removed, all drives disconnected, keyboard/mouse and printer disconnected. When you reboot, literally only the CPU, RAM, PSU, motherboard and monitor should be connected.

    If you're not seeing any POST (power on self-test) messages, I don't think I'd describe the PC as starting up "perfectly fine".

    The "CPU mode offset" is a CPU voltage control, normally used in overclocking. I don't see how you could have damaged anything by setting it negative. I suppose that if there was a large negative value, the voltage might have been too low to permit POST. (Seems unlikely.)

    Clearing the CMOS resets the settings to default.

    Just out of curiosity: your motherboard has an indicator LED for the DRAM. Does it light up?

    You could try WhyMe's suggestion of going to a minimal system to see whether it'd boot. Your CPU has integrated graphics, so you could use those instead of your nVidia card.

    PC turns on, No signal, keyboard/mouse.

    Yes when I turn the PC on with the RAM seated, There is a red light beside the RAM that flashes RED once, And then it dissapears.

    Ill try to clear the CMOS and use the jumper now with nothing connected but the PSU, CPU and RAM

    Okay I unplugged everything from it removed the CMOS battery and put the jumper from pin 1-2 to 2-3 again for around 5 minutes. I then reversed it and plugged the PSU in and VGA cable, The motherboard has a green light on it, I turned my PC on and the red light beside the RAM turns on for 2~ seconds then off again, But again my monitor is in standby mode, So I tried to put the HDMI cable into the motherboard and into my monitor and it says no signal.


    If there isnt anything else I can do would buying a new motherboard solve this issue, Or could the CPU be broken from changing this setting?

    I can order a new one from Amazon on Monday if it would fix the issue.

    Thank you.

    And don't forget to use the intel graphics instead of your card when trying to boot.

    I did I plugged the VGA cable into the motherboard, then I tried plugging the HDMI cable into the motherboard, no results.

    The GPU wasnt inside the PC or plugged in, The only thing on was the RAM, PSU, CPU and monitor connected up with both HDMI and VGA, still no signal.

    Do you own or can you borrow/get hold of a multimeter?

    What is your beep code? These are the codes listed by Asus for your board.

    PC turns on, No signal, keyboard/mouse.

    I don't own/have acess to a multimeter.

    And I haven't heard it beep, How can I make it beep? Ive never ever heard it beep.

    If the "beep" is a red light, there is one beside the RAM that turns on for 2~ seconds then its gone.

    The multimeter is to check your PSU, the PSU power cable, the PSU motherboard and cpu cables and finally the wall socket.

    The beep codes won't work if you do not have an internal speaker

    The thing is, you ideally need to confirm where the fault lies. I can easily post that I think it is likely you have motherboard error but that is meaningless as it is unproven and merely conjecture. If you just go straight out and buy yourself a new motherboard when the problem lies in the 24V motherboard cable then you would throwing a heap of money down the drain for example.

    So, for testing purposes.

    Take everything round to a friend or family who have compatible hardware. Hopefully one of them will let you check your RAM, CPU PSU (plus power cord) so that they can all be eliminated as the problem. In addition, try plugging another device into your monitor - maybe an xbox, blu-ray or whatever to confirm the monitor and it's cable is fine. You can check your current monitor cable when you test the other stuff round your friends/family. You also need to check the monitor power cord too.

    All of the above is a little out of sync. The point is, you need to identify the fault before splashing out.

    The monitor and VGA cable works fine, Im using it now on a seperate PC, Ive also tried seperate PSU cables.

    I also have a spare Corsair CX500M PSU laying around, I could take the CX750M PSU out and try the 500W one which I know works.

    Also have spare RAM, RipJawZ 1600Mhz 4x4GB, I could try that too.

    But I don't think the monitor is the issue as it isnt detecting mouse or keyboard either.

    I think changing the CPU offset from positive to negative prevented it from starting up properly, then when I reset the BIOS by taking the battery out maybe it corrupted the BIOS?

    I can try my other PSU if you would like.
