How to Troubleshoot a Computer That Won't Turn On
1:- Troubleshoot the cause of the BIOS error message you see on the monitor. These errors during the POST are usually very specific so if you've been fortunate enough to receive one, your best course of action is to troubleshoot to the specific error you see.
If you don't fix the problem by working through the specific error during the POST, you can always return here and continue with the troubleshooting below.
2:- Clear the CMOS. Clearing the BIOS memory on your motherboard will reset the BIOS settings to their factory default levels. A misconfigured BIOS is a common cause of a computer locking up during the POST.
Important: If clearing the CMOS does fix your problem, make any future settings changes in BIOS one at a time so if the problem returns, you'll know which change caused your issue.
