I've been struggling to get my new PC to boot for a week and a half now. The fans and lights work, and my keyboard lights up, but I can't get it to display anything. This PC is just a month old!
I've tried using two different monitors with HDMI and DisplayPort, but there's still no signal. I even switched outlets and rooms, but nothing changes. I've gone through two motherboards (an MSI B850 and an ASUS X870E), and both failed to show any debug error codes. I've flashed the BIOS on both boards without success and rebuilt the PC multiple times without finding any visible damage.
Everything seems to be running cool, with the CPU at ~38-40°C. Initially, the PC worked fine, but I had issues with it restarting, which required me to shut it down and turn it back on. It's gotten worse, and now it won't boot at all. I'm really unsure what to do next. Could it be a CPU issue, or maybe a faulty power supply?

Have you tried clearing the CMOS? It’s a simple step that can help. Also, set it up on a bench with just the CPU, motherboard, RAM, and PSU to see if it boots. When you turn it on after clearing the CMOS, give it a little time before concluding that it doesn’t work. What specific RAM did you use, and which slots are they in? That can make a difference too!
I feel you on this! The similar issue hit me with my old PC, where it wouldn’t boot but all the fans and lights were working. You're not alone paying a fortune only to face the same problem! It’s frustrating, but have you tried switching power outlets or using a different power strip? Sometimes the issue could be in the power supply quality.
If you recycled parts from your old PC, they might be causing the issue. Here’s a checklist:
- Reseat all connections, especially RAM and GPU, and don’t forget the power supply.
- Remove all RAM sticks and test each one individually.
- Disconnect all peripherals, except for the CPU, and hook up your monitor directly to the motherboard. If it boots, add components back one by one to identify the problem.
If it still won’t POST, it could be the power supply, motherboard, or CPU at fault. It’s all about narrowing it down methodically!
Yeah, I get it. I thought a new build would avoid those headaches! I have tried different outlets but still no luck. Just feels like I can't catch a break here!
