'Check Video Cable' error on boot?

[amith7798]

So, when switch on my CPU, the monitor displays a 'Check Video Cable' error. Anyone knows what's the issue?
I tried with a different VGA cable, same error comes up. When switching on the CPU, it's just black and then the error pops up. It then says 'Monitor going to Sleep'. The Monitor does seem to working fine.

However, no light comes from the keyboard and optical mouse. So guessing it's a CPU issue?

Welcome to HP Forums,

Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that your experiencing issues with the display, I appreciate your efforts to try and resolve the issue.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• What is the exact product number of your computer? If its HP's computer Use this link to find it: http://support.hp.com/us-en/document/c03754824 (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
• When was the last time it worked fine?
• Did this happen after a recent window or software update?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

Let's try these steps:

1. Move the mouse or press the Spacebar.

2. If the computer does not wake, press the keyboard Suspend button. You may need to press the Suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).

3. If the computer still does not wake, press the Power button on the computer case for one second and release.

4. If the monitor does not wake, restart the computer and turn off suspend mode:
