The video covers comprehensive troubleshooting methods for common issues preventing a computer from turning on or displaying output. Physical and configuration issues are key themes, with emphasis on thoroughly checking both types of connections, particularly with modular power supplies, and verifying correct monitor connections. The presenter highlights the importance of consulting the motherboard manual for connector guidance, as in the case of misconnected power LEDs causing startup problems.
Troubleshooting steps also include addressing persistent DRAM errors by methodically reinserting RAM sticks and resetting motherboard settings via CMOS reset, which helps revert to default system settings. BIOS updates are recommended to ensure compatibility with newer components, particularly CPUs. For display issues, the video suggests using BIOS to adjust PCIe link speed settings and replacing older riser cables with Gen 4 for enhanced performance.
Key points include ensuring the front panel power switch is not at fault, systematically checking VGA or graphics card connections, and verifying power supply adequacy. CPU-related troubleshooting focuses on proper power connection, resetting CMOS for overclocking fixes, and checking for motherboard shorts. Practical anecdotes reinforce the need for meticulous rechecking of connections. The video concludes by encouraging community interaction for additional support and knowledge sharing.

In this part of the video, the presenter addresses issues with computers not turning on or displaying anything. They discuss two main types of failures: physical issues (e.g., something not plugged in correctly or dead hardware) and configuration issues (e.g., motherboard settings). Common problems include not having all cables properly connected, like the ATX connector, CPU connector, and graphics card connection. The presenter emphasizes checking all connections thoroughly, particularly if using a modular power supply. Another frequent issue is incorrect monitor connections, such as plugging the cable into the motherboard instead of the graphics card, which can prevent the display from working correctly.

In this segment of the video, the speaker explains troubleshooting steps for a PC that wouldn’t power on, despite having RGB lighting. The problem was traced to misconnected cables, specifically the power LEDs being connected to the power switch. By checking the motherboard manual, the speaker corrected the connections, leading to a successful startup. The speaker also discusses an issue with the DRAM light staying red, indicating a RAM problem. The troubleshooting process involved turning off the power supply, removing and reinserting RAM sticks one by one to determine if the issue was with the motherboard or the RAM. Despite these efforts, the issue persisted, but eventually, the PC started working after a delay. The real issue was that the RAM was trying to run too fast for the motherboard, causing continuous boot cycling.

In this part of the video, the creator addresses troubleshooting a stuck ASRock screen during PC boot-up. To resolve this, they suggest turning off the computer, unplugging it, and resetting the motherboard’s onboard memory (CMOS). High-end motherboards may have a reset button, but others may require bridging CMOS pins with a screwdriver for 5-10 seconds to reset it.
After resetting, the PC should load default settings and display output. If the problem persists, they recommend updating the BIOS, which can be essential for compatibility with newer CPUs. The video also mentions issues with PCIe riser cables used in compact ITX systems, suggesting directly plugging the GPU into the motherboard if display issues occur, and adjusting PCIe link speed settings in the BIOS to Gen 3.

In this segment of the video, the speaker discusses troubleshooting steps for common PC issues related to riser cables and components. They recommend replacing a Gen 3 riser cable with a Gen 4 for better performance and describe a method to test if the front panel power switch is causing PC startup problems. They also suggest checking the VGA or graphics card connections and power supply adequacy. If using an Intel processor with an integrated GPU, one can remove the graphics card and connect the display directly to the motherboard to diagnose graphics card issues. For CPU-related problems, they highlight ensuring proper power supply connections, resetting CMOS to fix potential overclocking issues, and checking for motherboard shorts. The speaker shares an anecdote about a CPU cooling power cable oversight to underline careful rechecking of connections, and encourages viewers to systematically troubleshoot to resolve their issues.
