Question Pc now won’t boot

[hbrooks2813]

So i recently joined the pc community after building my first one a little over a week ago now. Everything was running just fine until this morning when i went to turn on my pc and it wasn’t booting up, connecting to my monitor, etc. I noticed a solid white light next to CPU on my motherboard. I tried looking it up and talking to my friend who excels in pcs and he is confident that my bios/cmos is being funky and causing my problem. I’ve tried resetting cmos, unplugging everything and plugging it back in, the whole shabang and i can’t seem to figure it out. Any possibilities?

Refer to the motherboard's User Guide/Manual to identify that "white" light (LED).

Determine what the light may be indicating by 1) being on, and 2) the color displayed.

This motherboard?

Do verify that I found the applicable User Guide.

Perhaps one of EZ Debug LEDs per physically numbered Page 36.

I went and checked the manual and it says that it means my CPU isn’t being detected or it’s failing. But the weird thing is that i was just playing on my pc last night and everything was fine. And when i was done i fully shut off my pc. Any possible reason why it’s being like this?

Yes.

The CPU may have simply reached EOL (End of Life) and failed. Even prematurely.

Try cleaning off and re-applying the thermal paste.

Late question: What wattage is the PSU?
