Hey everyone, I'm really struggling with my new gaming PC that I've had since September 12. It's a Mloong gaming rig with a Ryzen 5 5500, Radeon RX 6600 8GB, 16GB of RAM, a 1TB SSD, and a 650W PSU running Windows 11. From day one, it has had issues where it sometimes works and sometimes doesn't show any signal. At first, I thought it might be a problem with my monitor or cables, but everything checks out fine. I noticed a strange issue: when my phone charger was plugged into the same outlet, the PC wouldn't display anything. Unplugging it fixed the display, which made me furious because I expected a professional build to just work. Now, I can't get any video signal, no matter what cables or monitors I try, and I've checked everything from the GPU seat to the PSU. The PC powers on, the fans spin, but there's no video output. I feel completely cheated because I paid good money for this prebuilt and now I might have to send it back for warranty repair. Has anyone experienced similar issues with cheap prebuilts, and do you have advice on how to handle this with the manufacturer?

It sounds like you might be dealing with a power issue related to your home outlets. The fact that your PC refused to show signals with your phone charger plugged in suggests that there might not be enough voltage going to your PC when there's too much load. It could also be a grounding issue in your house, so definitely test that out. It may be worth trying your PC at another location to see if the problem persists.
One common trick: try removing one RAM stick and see if it boots, then swap and try the other one. Sometimes a faulty RAM stick can prevent any signal from getting through.
Given that your PC powers on but has no display, you might need to update the BIOS. Sometimes, prebuilt systems come with outdated BIOS versions that can cause issues with hardware detection. Check if there's a newer version available for your motherboard.
Don't hesitate—contact Mloong immediately! Make sure you're firm and document everything about your situation. They should cover return shipping for DOA units. If they push back, let them know you're prepared to dispute the charge with your credit card company. If you ordered through Amazon, going through them for a return can often be quicker.
Have you checked how your RAM is configured? If you only have one 16GB stick, consider testing it with two 8GB sticks—or vice versa—if you have them. Also, you didn't mention your motherboard model. It would help us look up specific issues related to your hardware.
