Can you restart at the safe mode with command prompt and reinstall the network driver from a usb thumbdrive?

Welcome!

If Roger's suggestion doesn't work, I suggest a system restore to get to a point before the troubles began.

Safe mode no longer works , restart repeats, i press system restore button and nothing happens it just goes to Start up as normal etc. very limited options...

Try a system restore from the repair disc or Windows DVD.

i have only a xp boot disk no windows 7... the xp doesnt work on HP laptops

You can create a Windows 7 repair disc: System Repair Disc - Create

LOL...what does that mean?
