<human>:  How do I troubleshoot my computer if I can't get it to boot up?
<bot>: Firstly, try to determine if the issue is related to hardware or software. If you suspect that the issue is related to hardware, check if all your cables are connected properly and if you can reseat your RAM or other components. If you suspect that it is a software issue, try to boot into safe mode or try to perform a system restore. Additionally, you can try to reset the BIOS settings to their default and see if that helps. If all else fails, you might need to contact a technician for further assistance.
