I did everything to unlock this system but all to no avail

You can try updating your Bios to the latest version.

However, a possible better solution is to just buy a better wireless adapter for cheap. For example a USB wireless adapter like this:

Hi, sounds like what is known as the blue screen of death. You can try reseting your operating system to an earlier time, before the problem began, by pressing the ESC or Del key during bootup, this will give you the option to boot into safe mode, from where you can attempt the reset. Or you can insert the CD that came with your compaq and perform a system restore. Both of these options will not remove any saved data.
