Help me please! (PC)

[Mazxd3]

Hey everyone! 

I moved from Sweden to Turkey and I brought my pc with me on this long trip.  Now I'm trying to turn on the pc and everything works like fans, graphics card and RAM(They are RGB) .  The problem is that the screen is black and nothing appears.  When I start the computer I can see many numbers that appear on the motherboard and the last number is 02 and it's doesn't change anymore.
I tried to rebuild the pc again to solve the problem, but I face always the same problem.  I have tried to keep 1 ram.  I removed the cpu to see if the pins were damaged but everything is fine. I have tried to clear the CMOS to reset the BIOS settings but same problem. Someone recommended me to clean everything with an alcohol and toothbrush, will this fix the problem? Thanks for anyone that will try to help me out! I will write my pc specs under the text. Sorry for my bad English.

Code 02 (probably) means the system thinks it's sitting in the BIOS and nothing is wrong.

 

Try different ports on your GPU and your monitor. Try a different HDMI/DP cable. Try a different monitor entirely if one is available.

 

Cleaning anything is highly unlikely to make a difference unless you have some reason to believe a foreign substance got in the system during transit.

 

When traveling with or shipping a PC long distances, it's always best practice to remove the GPU and the CPU cooler at the very least and pack them separately.

those numbers are error codes you need to solve to get everything running again..  try to write them all down then you consult your mainboard manual and take it from there. sounds like you reseated your GPU and PCIE powercords in the rebuild but check if everything are properly connected again.

No.

 

Motherboards with debug LED indicators normally flash through many codes very fast on bootup, these indicate all of the different systems that are being checked and initialized. If there is an actual problem that prevents the system from booting one code will appear and remain, or some boards will display a code even on a normal boot that just basically means "Everything is fine, handed off to the OS." I had an Asus Crosshair board that would, IIRC, display code AA for this the entire time Windows was running, for example. 

 

To reiterate, many codes flashing on the debug screen during startup is normal.

To the above I will add that I watched the debug LED display on my ASRock board last time I booted up and 02 is the last code it displays before going dark, right when the Windows sign-in screen pops up. 

 

I strongly suspect, @Mazxd3, that your problem is somewhere on the GPU-display-monitor side of things and your PC has booted more or less normally and you just can't see it.

Hey!

Sorry for being late. I have already tried 2 monitors but it's the same problem. Do you think that the motherboard is dead? I see only black screen. I have tried to connect my monitor to motherboard hdmi and yes it's the same problem. Is there any solution that can help me?!

I have already rebuilt my pc twice! Same problem unfortunately.

Most point to a BIOS update - wrongly selected DP version being unsupported - trying new cables (HDMI or DP) and so forth.  I'd try these - then you can try doing a barebones type of boot (CPU, 1 RAM Stick, Boot SSD/HDD and GPU - since the 5900X has no integrated GPU - plugging any display cable into the Mobo is pointless).

Hello and thanks a lot for the help.  My problem is different from them because my computer was working fine before I traveled.  I use the same screen I used before I traveled.  I have tried two different monitors but unfortunately the same issue.
