HP Pavilion gaming pc no input detected

[papersurfer]

Ok so when I connect my pc to my monitor via hdmi it says that I have no inputs detected. I switched home cords, same problem. I took the RAM out and dusted it off (even though it seemed it really wasn't dusty). I looked through the inside and it looks like everything is fairly normal, there isn't any obvious issues except some dust in the fan. It makes a beeping noise when I turn it on now that I'm not sure if it always made. I know absolutely nothing specific about computers but I need this one for work so if anyone could help it would be appreciated.

Welcome to the HP support community.

I understand that no input is detected in your computer, I am glad to assist you.

Update the Bios, chipset, and drivers using HP Support Assistant.

Download and run the HP Support Assistant from this Link: Click here

• HPSA will automatically search for all the latest drivers for your Notebook
• Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
• 
• Click Check for updates and messages to scan for new updates.
• 
• Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
• Click the update name for a description, version number, and file size.
• Select the box next to any updates you want to install, and then click Download and install.

Also, ensure Windows is up to date.

• Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
