Hello All,
I have a Sony Vaio machine with 512 MB RAM, 3 Ghz CPU, XP, SP2. Over past several months it has frozen innumberable times. When I have lots of applications open at once, it freezes up which is understandable considering I have only 512 MB of RAM. But here are situations which I am clueless about:

1) I log in as my user name , open up fire fox (ver 1.5) and it freezes up. Windows task manager tells me alwasy that there is just 1% cpu usage. I have no clue what its doing.

2) Sometimes when I have to open firefox and IE together , same thing happens.

Even if I kill hte processes it hangs forever. I wait for 10-15 minutes and in frustration have to pull the power cord each and every time. Very frustrating. Any help would be appreciated. Here is my HijackThis log file.
