Question Black screen crashes

Jan 27, 2019
Hi All

Recently my system went crazy and I'm experiencing random crashes (simple black screen with no reaction at all or black screen with buzzing sound)
Haven't changed anything hardware wise in the system, it started randomly.


  • 1. Intel Core i5-4690K, 3.5GHz, 6MB, BOX
  • 2. Sapphire R9 390 NITRO, 8GB GDDR5, 512 Bit, HDMI, DVI, 3xDP, Box
  • 3. Cooler Master HYPER 212 EVO
  • 4. MSI Z97 GAMING 5, Intel Z97, 4xDDR3, 1xM2, VGA, GbLAN, ATX (Z97 GAMING 5)
  • 5. Corsair Vengeance Pro 16GB
  • 6. Intel 535 240GB SATA3
  • 7. Zalman ATX 700W
  • 8. WD Blue 1TB Desktop Hard Disk Drive - 7200 RPM SATA 6Gb/s 64MB Cache
Crashes started at first only while gaming but nothing really stressing. After that system crashed even when i left the PC running overnight just with a movie going on.
Had initially Win 7, swapped to Win 10. (64 bit Pro)
Never did overclocking.

Troubleshooting done:
  • Bios updated
  • SSD was the boot drive, removed it and using HDD as boot
  • Recabled the whole PC internally
  • Dusted out the PC
  • Thermal paste replaced on the CPU (max temp 70ish decreased to 60C max under heavy pressure)
  • Tried multiple versions of graphic drivers
  • Changed the graphic card's PCI slot
  • Changed the memory modules slots
  • Tried with only 1 memory module at a time
  • Installed Afterburner and increased gpu fan speed
  • Run multiple memory tests
  • Run Prime95 test for over a night
  • Checked windows event logs (nothing showing there)
  • Multiple reinstalling on OS
  • Uninstalled MSI AB and changed Wattman settings (instead of dynamic settings i set every stage to max level mHz and mV wise and set power limit to +50%)
System is just a bit under 3 years old.
The biggest improvement I achieved was when thermal paste was replaced on CPU and turned the GPU fan from auto to manual (50-70% fan speed in the 50C zone)
System was stable for over 2 weeks without any crashes and GPU nor CPU temp ever went above 60C even with heavy gaming on max settings with stable FPS.
Then it started again for a day, then suddenly was ok for next few days, then again crashes.

Just to make it more puzzling, yesterday played all day Satisfactory (alpha) on ultra graphics (UE 4 engine) not a single crash). Today when i started the game, crash.
But also got crashes few days ago when i started Warframe and started downloading a 3 gigs patch for it.
Had crashes while playing Dota 2, never crashed with They are billions, then tried out Subnautica below zero which crashed like hell in less than 10 mins, after that i changed the thermal paste on CPU and no more crash(although played it only for 4-5 hours).
Played Anno 2205 for 4 days, not a single crash.
Then started to play warframe first 2 weeks absolutely no crash (always on ultra settings) after it i got several crashes daily. (even while i was just patching the game or had crash when i was changing the graphics from ultra to low).
Just now i changed the wall socket where the PC is plugged, checking if that would change anything.

Any thoughts?

Is your PC still on and the Monitor is just acting like its not plugged up the PC? i get this randomly, playing any variety of game, at the worst times. i know its not a heat issue because it happened playing league of legends, and my temps were way below any kinda of risk area. It happens when i play warframe, but only in the plains of eidolon areas. but sometimes i wont happen for weeks. ive tried soooo many things to fix it. i dont have any of the same hardware you have either... sorry this probably wasnt helpful.
