I have just recenlt downloaded spybot s&d onto my girlfriens computer but when you load it up and press 'check for problems' the program stops responding. I have tried this many times and still haven't had any luck. I have also uninstalled it and installed it again but it doesn't seem 2 work.

System specs.
Os -windows xp
Processor - intel p4 3.00 ghz
512mb ram
80 gig hd

Try running Spybot: S&D in safe mode. Some bits of spyware now try to detect programs like Spybot: S&D and make them crash/not work etc. to prevent themselves from being removed.

Here are some instructions on getting into safe mode (http://www.computerhope.com/issues/chsafe.htm)

Hey I tried it in safe mode, still to no avail! Could it be conflicting with norton or is it just it doesn't want to work on her computer?

I doubt it's Norton. Where did you download Spybot: S&D from? Was it http://www.safer-networking.org/en/index.html ? Also, are there any error messages or does it simply just hang?

I downloaded it from www.download.com. When you click on check 4 problems it hangs. And I've also downloaded it from that link as well

Try running AD-Aware instead - maybe that will remove something that lets spybot work!
