Hey everyone, I’m really struggling to figure this out. Usually I have a clear intro or start-up sequence, but now everything feels chaotic. Let me walk you through it. I’ve been dreaming about getting a gaming PC for years. About four months ago, I finally bought my first one—step by step. I began with the graphics card and power supply, then a few weeks later I got the main machine. After a couple more weeks, I added 4 gig of RAM to the existing 4 gig. The system specs are: RX570, Intel i5 2500, four 2-gig DDR3 modules, and a 500-gig HDD (3.5"). It runs on a Dell Optiplex 790, which is familiar from my past builds. I saved up slowly; even selling my old laptop helped me reach this point. But then something went wrong. Two weeks ago, when I turned it on, the PC didn’t power up at all. The fans are running, but there’s no screen. I tried an HDMI cable from a friend—it worked for two days. Then the issue kept coming. At first I thought the GPU port was damaged. Later, I bought a DisplayPort adapter because my GPU has three ports. It connected for a short time, then nothing. I became worried about losing the GPU entirely—no budget for another one. I considered the monitor as the culprit, so I swapped it in with a laptop and it worked. Then I took it to the living room to test on a TV, but still no display. The GPU fan is spinning, and I’ve checked all connections, ports, and even tried resetting the BIOS battery, RAM, and drives. Still nothing. I attempted to use integrated graphics by plugging in a DisplayPort through the motherboard, but that didn’t help either. I’m really anxious because admitting the GPU is dead would be a huge setback—I can’t afford another purchase. It’s frustrating, especially with the performance issues: 800p at 20 frames per second, constant stutters, long load times. This situation is really stressful.
Start the device with just a single RAM stick and leave all external drives off. Run the built-in camera if available and reinitialize the system settings.
I’d look for any spare GPU, ask a friend for one, or find an old unit nearby. If you have onboard video, use it too. Any swap should help determine if your device is faulty.
Ive tried onboard graphics but no post as well, the thing is crazy at this point
It seems likely they’re limited to options since it’s an OEM PC. They’d probably need to source a replacement from another OEM or buy a new one from platforms like FB Marketplace. Based on their budget, even affordable Chinese boards on sites like Amazon or Aliexpress could work.
