Final answer:
To troubleshoot a computer that has no beeps and no video during the boot process, check the power supply, cables, motherboard connections, RAM, and expansion cards. Test with a minimal hardware setup and consider potential short circuits. If unresolved, CPU, motherboard, or PSU could be at fault and need individual testing.
Step-by-step explanation:
When you start the boot process but you hear no beeps and there is no video, it suggests that there could be an issue with the basic hardware components of the computer. You can begin troubleshooting by checking the power supply, ensuring that all cables are securely connected and that the power source is functioning correctly. Next, you might inspect the motherboard connections, including the RAM and expansion cards. If everything seems to be properly connected, you could then test with minimal system configuration by removing all non-essential components to rule out peripheral conflicts.
Additionally, make sure the motherboard is not short-circuiting with the case. If these steps do not resolve the issue, the problem could reside with the central processing unit (CPU), motherboard, or power supply unit (PSU). In such cases, it might be necessary to test each of these components individually, potentially with the help of another working system, to pinpoint the failing part.
