About to throw computer out window, help!

Please help if you can. On my laptop I installed ad-aware se and did the scan but it froze when it got to a CLSID file while it was deep scanning the local registry. so I tried to install HijackThis on it but every time i try to open hijackthis it says that it has encountered a fatal error and doesn't load. Is there anything else that I can do? PS....this really started to be a problem when I tried to use my wireless internet...but I uninstalled the wireless nic and the problem persists. can anyone help? PSx2....just found all of these Windows XP Hotfix (SP2) on my programs that are installed....I haven't a clue what these are???
If anyone can give me just a little bit of information about what this might be or what they think about it i would really appreciate it!

 

Try running adaware in safe mode.
