I have a Compaq presario F500 laptop. i bought it roughly last september (07) and it has worked fine. about or month or so ago when i flicked the switch to turn the wireless on the light did not change colour and i couldnt connect to the internet, after a little more investigating my laptop told me i didnt have a wireless network adaptor. it has not been working since then except for a couple of occasions which are about 2 weeks apart where it will work for a half hour or so. after i turn my laptop off after it having worked it will not turn on. Could this be some sort of virus or is it just the laptop? thanks

I would assume that your hard drive is spinning? If not your system will not boot because of a faulty or missing harddrive. Last known good config only works on the operating system and would not work during POST. Can you give a little more information please?
I tend to not use HP or anybodies Wireless Assistants. But you ought to be able to see in Device Manager and Networks wether Windows thinks that the wireless card is working or not. Windows uses Wireless Zero Configuration Service to control Wireless Cards. You might have to tell the HP gizmo to let windows manage the wireless.
You might also have to turn the computer over and find where the wireless card is - and check that it is still seated properly in it's slot. That's a pretty advanced thing - and should only be done with the Service Manual or Owners Manual at hand to tell you how.
Mainly the hardware should be showing up in the Device Manager as "working properly" - if not maybe somehow the device driver software got damaged or removed?
RESTART YOUR COMPUTER, ON REBOOT, CLICK F10 WHEN YOUR CHANGE BOOT OPTIONS SCREEN COMES UP. YOU MUST PRESS F10 QUICKLY OR IT WILL LOAD WINDOWS AND YOU WILL HAVE TO RESTART AGAIN. ONCE YOU GET INTO THE BIOS SETUP UTILITY GO TO SYSTEM CONFIGURATION, SCROLL DOWN TO BOOT OPTIONS CLICK ENTER. GO DOWN TO INTERNAL NETWORK ADAPTER BOOT AND ENABLE IT. GO TO EXIT AND SAVE. AFTER YOU RESTART YOUR COMPUTER IT SHOULD WORK.
Right click on my computer, select properties, select device manager. Is there a yellow triangle in the network adaptors? If so then go to http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=3689054&lc=en&dlc=en&cc=us&lang=en and download the wireless driver for your computer.
