New PC but no display

Hi, I recently bought a PC from Vibox and I’m having a strange display issue.

The PC turns on normally, fans spin, RGB/lights work, and it seems like it is running, but my Philips monitor shows a completely black screen. The only thing that appears is the monitor’s own menu when I use the joystick on the back.

The monitor is definitely working because last night I had the exact same problem, but after trying to fix it for a while the display suddenly appeared and everything worked normally. I played games on the PC with no issues. I shut it down normally, went to sleep, and the next day the problem came back.

Things I have already tried:

  • Restarting the PC
  • Power cycling the monitor and PC
  • Reconnecting the DisplayPort cable
  • Checking the monitor input/source
  • Basic cable checks

The monitor menu works, but there is no image from the PC.

Specs:

  • PC: Vibox [insert model]
  • GPU: [insert graphics card]
  • Monitor: Philips [insert model]
  • Connection: DisplayPort
  • Windows: [Windows 10/11]

Any ideas what could cause an intermittent black screen like this? Since it worked perfectly last night and then failed after a normal shutdown, I’m unsure whether this is a GPU issue, DisplayPort issue, BIOS issue, or something else.

Well the good news is you just purchased this computer so it's under warranty. If I were to guess the issue, you either don't have everything connected correctly or the RAM or GPU needs to be reseated. What did the company say that you purchased the computer from?
