Sighhhhh

I get the dust issue. The gpu is done, that's not a question. The problem now is that the pc wont even power on. I shouldn't need a gpu just to power on the case and motherboard. I was wondering if anyone knew about the red light indicator if maybe there may be another internal issue such as the motherboard or maybe the buttons on the case may be fried itself.

Apparently his gpu started smoking and now the pc wont power on. Theres a solid red light at the top left side of the motherboard so I'm assuming there's power going to the pc bit when pressing the power button, nothing happens. Would this mean there's something wrong with the motherboard? And yes I know the pc is dirty I'm equally as disgusted.

Okay so I'm having issues. My computer was working perfectly fine for months then I upgraded to a ryzen 9 3800x from a ryzen 7. When switching cpu's things ran smoothly so I went for the overlooking. Instead of using the bios, I used ryzen master where I overclocked the cpu from 3.8 to 4ghz and only enabled manual overlooking of the ram for when I was done with the cpu. Well I then restarted the pc and it refuses to post. It takes me to a screen asking me to optimize my bios. There wasn't anything to optimize so I exited. After leaving it restarts to a blank black screen with an error code posting as 0d on the motherboard. I tried clearing the bios with the button on the back and I get returned to the same configuration bios message which the black screen happens all over again. I tried hitting the restart button on the mb... nothing I tried a hard restart with the start button on the mb... nothing, same black screen. I even tried the safe startup and retry bios button on the bottom of the mb... no luck. I even removed the batter from the darn thing hoping it would do something but no luck. I was thinking the ram was fried but at the same time it recognizes the installed ram. For the love of God, does anyone have an answer? I'm close to shooting the pc out the window (not really though -_-) Specs: crossheir viii hero wifi motherboard Ryzen 9 3700x 32 gb Ballistix ram Gigabyte rtx 2080 graphics card Windows 10 64 bit
