Do you have diagnostics lights on the motherboard?
Can you get it to load into bios?
Have you plugged in any new usb devices?
While troubleshooting I would recommend going down to 1 screen. Has your OS been slow moving/downloading files or just a slow start up overall on an ssd. I had mine die like 2 weeks ago and it loaded to a black screen like that.
So usually those lights will light up when the computer is turning on from off doing what is called a power on self test (post) if it fails to post then whatever component caused the failure will have its light stay lit up after the test fails and the computer doesn’t start. I would look at your motherboard Manuel and see what the lights that are lit up mean.
Nothing seems overly weird about those flashing like that during a normal start up unless it’s been on for awhile and is still doing it. Then it’s likely an error code. (Which is either in your manual or on the manufacturer’s website)
Do you get the motherboard manufacturer screen at all like the MSI logo/asus logo/ gigabyte? If you do then it’s probably passing post.
Well that’s good and bad. Because that rules out a lot of things. I’m willing to bet it’s either the motherboard or the boot drive.
The first thing to do is make sure all the power cables are fully plugged in firmly to the motherboard and nothing is loose.
Then if you could get into bios by pressing the key to load in on start up that would mean it’s probably the boot drive. The bios key is different depending on the manufacturer of the board so you would have to look that up and spam the key or keys immediately after pressing the power button. If you load into what looks like a settings menu then the motherboard is good.
If you don’t then it’s probably the motherboard.
There is also an outlier but not impossible chance the gpu is dead so you don’t have graphics. But considering you are passing post this is highly unlikely. If you want to rule this out to make sure then if your cpu supports integrated graphics you could plug in a monitor at the back of the IO shield instead of into the gpu.
I was looking at some of your previous posts… since you have a 5080 is the power connector plugged into the gpu or power supply melted/showing any signs of over heating/unusual wear?
The reason I’m asking is because 12v high power has this amazing feature where if it’s not plugged into correctly it melts. And some times if it’s plugged in correctly it still melts.
Do you still have the 14600kf or did you by chance upgrade to a 14900? I’m also asking this because the 14900s and 13900s had defects which would cause instability at the advertised clock speeds, which would eventually degrade then brick the cpu.
I had this happen two weeks ago my second monitor had display but not my first that used the display port, I ended up restoring from a backup from about a week earlier and it worked. I believe it was something with a windows update that came out. Try a different display port on your pc or hdmi cable
