    Screen displays 'no signal detected', mouse and keyboard not working


    Hi everyone.

    Recently I've run into a problem that I couldn't find solution to anywhere or any kind of answer. A few days ago there was a windows update and until then, my computer was working fine. But since the update, my computer "crashed" twice. Now, I put air quotes on crashed because it's not really what I would call it. I was listening to music, surfing on internet and working on something in Word when all out of sudden my screen showed 'no signal detected' message and I thought that maybe it'll last only for few seconds because I thought my graphic driver was updating because I saw that I had a new update from NVIDIA. But then few seconds passed and then I realized that neither my mouse or keyboard were working so I decided to restart my computer thinking maybe it just froze (which still didn't make sense to me). I tried turning off my computer by pressing power button for few seconds but nothing happened. Then I tried both restart and power button again but to no avail and I had to turn it off by turning off the power switch. When I turned computer back on, everything was fine as if nothing happened, as if I turned it off completely normally. I couldn't find any crash reports or anything but since everything was working fine I just let it go, thinking it was one-time thing. Except it wasn't and it happened again today. Same thing. Computer works just fine, like nothing happened.

    Does anyone know what could be causing this? PSU or motherboard perhaps? Or is it something entirely else?

    EDIT: It turned out to be both PSU and motherboard. PSU slightly fried the motherboard and that's why it was acting out. I'd say case closed.

    Hi novaforce

    Myself, I doubt this is hardware related, everything was working, then you see and update and it goes south. Of course I could be wrong.

    I would look in your your update history for driver updates, any and all. You said nVidia just updated. I would start there with rolling back driver.

    Have a restore point and for good measure an Image of your OS just in case. If you don't have a tool may I recommend Macrium Reflect. Free, recommended and reliable.
