Yesterday afternoon, I was doing work on the computer on excel and post completion, I launched a Warhammer Total war to play before I headed off to work. Fast forward 15 minutes after my lunch and upon returning to computer, the game was stuck (as in crashed), and neither my mouse or the keyboard were responding (The red led and the blue Led were gone).
The image of the game was still present on the display.
No artifacts from the gpu that I observed.
I rebooted the computer, only to be met with a black screen, no boot, and "No display detected" on the screen.
Post rebooting again and getting the same message, I thought something happened with the gpu so I removed the display cable and plugged it into the motherboard display port (the one that is attached to the motherboard). Result? No display and neither keyboard or mouse were on, again.
Opened pc tower and started checking for any loose connections. None were found, but I removed everything and re-installed them. Booted up the pc - nothing. Fans spin on cpu, computer power button works, led turns on, pause fans turn on, and gpu fan (below the gpu) and the water pump radiator fan, both turn on. Furthermore, the gpu starts pumping thr liquid without a problem.
No display, yet again.
I uninstalled one Ram stick and swapped places. No display.
Uninstalled both Rams and booted. No display and no beeping sound or Led flash from the motherboard about missing both ram sticks.
I removed absolutely every component from the case and one by one, checked them. HadHead-on off - no display. Ssd data disconnected too - no display.
I took the psu downstairs to my brother's pc and launched it. - no problems with the psu. It works fine. No failure. No smoke. No odd noises, no sudden shutdowns even when launching ac odyssey game thing (hope I did not butcher the name).
Swapped his gtx 1050 Ti with 1070, it worked fine and the temps displayed were all normal.
That is how I came to the conclusion thet it has to be VRM as aside the cpu fan, no other part of the motherboard is working. I don't have the equipment to check each pins for voltage, which is why I was thinking about taking it to the computer shop.
Thank you for hearing me out and I apologize for the long post.
And above all, thank you for all the replies! It might not show that I am panicking but I am quite in a panic mode... this computer has been with me for 4 years and i am quite attached to it, even if it is just a hardware.
