Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I understand you are having issues related to Bios on your HP Compaq Desktop PC. Don't worry I'll do my best to help you with this.


After reviewing your post thoroughly, I did go through the specifications and found that this PC was shipped with Windows 7, however, you have installed Windows 10.

After doing a bit of research found that this PC is not tested for Windows 10, for more details, please go through this support link: HP Products Tested with Windows 10


This could be one of the possible reason why the BIOS and IDE configurations are blank.


I hope this answers your question. Let me know if you need any further assistance. I'll be more than glad to help.


Feel free to post your query for any other assistance as well,

It's been a pleasure interacting with you and I hope you have a good day ahead.

If you wish to show appreciation for my efforts,

From: Compaq Presario CQ3220AN Desktop PC Product Specifications


Product number: VT566AA

Release date: 11-Dec-2009
Country/region sold in:
  • Australia
  • New Zealand

HP states that all HP computers manufactured after August 2013 have been tested with Windows 10.


Anyway, disconnect the AC power from your computer.

Disconnect the power and data cables from your motherboard.

Then, reconnect the AC power, and boot your computer, immediately and repeatedly tapping F10.

If your "vintage" computer is OK, it should POST (Post On Self Test) and should enter BIOS SETUP.

If it is not OK, it's time to consider a new computer.
