Question

Computer fails to boot up

This morning i was turning on my computer, as usual. But instead the normal windows 10 start up screen my monitor just says "no signal". I also notice that my keyboard and mouse are not lit up, they have that kinda cool light that lights up pretty much the second i turn on my computer, but they're off even though i can hear my fan running, i can see my cabinet light is on, but my monitor doesn't have a signal and neither my mouse or keyboard are working.
I tried removing the CMOS battery so i could clean it, and i also cleaned both my RAM. I am completely stuck, I could really use some help. Thank you so much in advance

My specs are Windows 10 Home, AMD FX (tm)-8320 eight-core processor 3.50 GHz, 16GB RAM, and my video card is AMD Radeon HD 7950

This is not a W10 issue yet.

This one looks like a failed PC. If the USB lights are failing as well on keyboard then it's a real hardware issue. I don't know if you are a PC tech with a Volt meter but I'd measure the rails first.

I agreed with Robert.

It could be anything pertaining to the hardware. There's no way we can tell you how to isolate the problem over the internet, it's just too many possibilities. I would start to see if the power supply is good or not. No power alone do not necessary mean the PSU is bad. You might do a search on how to do this.

Why not cut through some issues first

If you can create some Linux Live disk/usb , you will see if it's a hardware problem.
While running the Linux Live disk/usb, if everything works as it should, it will fall back to a Windows problem.
It's a simple, reliable test
