Hello humans and welcome. My PC has some issues that even I couldn't figure out, but I have a hunch. So, if I turn it on, the CPU, drive, exhaust fan, and GPU would turn on, but there would not be a display. I tried removing the CMOS, switching PSU from 650W to the 250W it came with, reseated the RAM, tried booting without RAM, tried booting with no drive, tried using the DP on the motherboard, not the GPU, but that thing refused to display. Went to a PC store and told the guy the same thing; he reapplied thermal paste, and boom, it worked (note the CPU wasn't overheating or anything; I know the temps). Maybe 3-4 days later, we were back to square one. I tried reseating the CPU, but nope. Three weeks after the CPU had been sitting and collecting dust, I took it for a check again. This time, the guy reseated the RAM, and that boot up, like bruh, I did that before coming and didn't get any POST. I ended up getting 4GB of extra RAM (new) because he said the RAM was weak, I guess. Three days later, boom, back to square one, but this time, if I boot the PC, the keyboard light (CAPS, Num Lock) turns on; I don't know if that means anything. Now, if I turn on the CPU, there's a 50/50 chance it would work, and if it does, the PC would be working for like 2 days, and maybe on the 3rd day, it wouldn't post again, no matter how I try. Sometimes it only works for a day, maybe 2, and yeah, same same, been a month or so. Oh, and I did a diagnostic test of the hardware, and it all checked out. I got a new drive for a fresh Windows install, but nope. I reinstalled drivers with DDU, and it's not my PSU because, at the beginning, I mentioned swapping the PSU. This is a long message, but I hope you find it somewhat useful. Thanks for reading.
Switching to a weaker power supply offers little insight. Most of your comments suggest GPU or memory issues. Without complete specifications it's tough to pinpoint the problem. If you can, test with another CPU. Given you have 4GB RAM, it seems like a DDR3 system. That usually means a standard motherboard.
i5 2500 gigabyte rx 570 with 8gigs and 12gigs DDR3 4x3 COASTER TX 650w. This setup uses a Dell Optiplex 790 motherboard, CPU, and drives—it’s not brand new or pristine, but it’s been used before if you’re looking for it.
I didn’t check if there’s a PSU issue, since I booted the PC using the specs I received. It has an i5 2500, an RX570 with 8GB and 12GB RAM, DDR3 4x3 COASTER, and a 650W PSU. The GPU looks fine—it hasn’t been used much and there are no signs of overheating. My guess is the motherboard might be the problem, as it’s hard to find chips locally but not impossible.
Hello there! I’ve shared this post for a while now, but I think it’s worth revisiting. Here are the details:
Specs: SPECS I5 2400 Dell OptiPlex 790, 8GB RAM (now 16), 1300MHz DDR3, RX 570, 8GB.
I went through all troubleshooting steps possible and still can’t get it to post. RAM CMOS CPU PSU hard drive. I even replaced the RAM sticks, changed the motherboard and CPU, but after a long day at work, I plugged everything back in. It spun like a vacuum cleaner—functioned when tested with a different GPU at the shop.

It’s really frustrating. I’ve spent a lot of time trying to get this GPU working, but it just wouldn’t cooperate. I noticed some rust on the PCB, a bit of corrosion on the back plate and ports, but it worked fine until now.
Purchase history: Around $48,000 for mine or $33 USD at the time. Now it’s about $110,000 due to inflation.
I’m worried about going back to square one because I don’t have a backup plan. Any advice or information would be greatly appreciated. Thanks!
Have you experimented with another video cable? Could there be a problem with your home’s electrical setup or grounding? In my experience in Indonesia, this was frequently a concern.
