Windows Booting, nothing appears (no bios splash screen) all black

My other components are already on,
- cpu fan on
- gpu fan on
- no input (keyboard) detected
- monitor stays off
- no HDD blinks (on cpu case)

my pc specs :
amd fx-6300
motherboard msi 970a-g46
msi r9 280
1TB WD HDD
Windows 10 64bit

Previously it works like usual, but GPU card display some artifacts and then I unplug the GPU card change the thermal paste and some cleaning. I restart the computer, now doesnt work at all even cant display BIOS.
My GPU is dead? Used 1 year+ (16 months)

    In short Oxid,

    You need to find someone who can do a reflow on the Ati 280 card.
    I don`t know how bad your artifacts were on the screen when the card was working.

    But if the artifacts were present when at the windows desktop, as much as when you attempted to play games with it.
    It can point to either the Gpu it`s self at some point and the solder contacts under what we call the BGA array of the gpu chip being un soldered from the cards circuit board.

    Like wise the memory chips on the graphics card can suffer from the exact same problem.
    A re flow lets the tiny solder ball grid array under both types of chips to reconnect to the point of the circuit board where they should be soldered too.

    You can also try this yourself if you feel confident enough to do it.

    Just look on Google for: re flowing a graphics card, most come with instructions on how and what to do.

    Other causes to why a display image can be garbled, more to the point of totally unreadable with huge colored blocks when the system is posting are related to bad, or blown capacitors of the graphics card.

    Yours by your rough description points to a break in bga solder points of the Gpu it`s self.
    And why you get no screen output image at all.

    my windows is working like now, i dont know why but it just happened when i turned off the pc all night long.

    the artifact seems a little bit weird to me, i have 2 monitors. 1 dell 1080p (hdmi) and 1 acer 900p (vga).
    if i use the acer one, stress testing my cpu it wont give artifacts, but i tried play game thru dell monitor the artifacts came again. it becomes green and has lines

    is it because the connector?
    thanks for answering
