Facing issues with my tower server, need techies' help

I’m facing some issues with my tower server and I’m seeking help from fellow techies. I’m not very knowledgeable about servers, so any assistance or suggestions would be greatly appreciated.

The issue I’m facing is that my tower server is randomly shutting down. It happens frequently, and I can’t seem to figure out why. The server is not overheating, and there are no obvious signs of hardware failure. I’ve tried troubleshooting it myself by checking the event logs and running diagnostics, but I haven’t been able to pinpoint the issue.

I’m using the server for hosting a website and some applications, and it’s crucial for my business operations. If the server keeps shutting down, it could result in downtime for my website and loss of potential clients.

I would really appreciate any suggestions or advice on how to solve this issue. If anyone has experienced similar problems or has expertise in server troubleshooting, please share your thoughts and insights.
