win32 crashing

i started to get a error last week everytime a popup came up and said something host has crashed in win32.exe everytime it crashes my dialup modem crashes it still shows me as connected and if you pick up the phone you can hear it still going. but i am thin unable to view any pages on the internet and i cant get it to disconnect unless i restart my computer and unhook the phone line. below in my sig are the spec's and below is 2 pics of the error

i am thinking my modem is dieing but could i be worng?

 

ok i was just going through event viewer and found quite afew errors some not worried about but the others i am heres some pics of them they seem to tie into the problem

 

Part 2

tim i already deleted the temp. files my anti-virus has not turned up anything but i will try a online scan for ya

 

yea i am running a small network via a crossover cable

 

yea i beleave it is all i use it for is playiing a friend a network game.

 

hmmm is there anything to be worryed about?
Avast says that part of the panda download is a virus should i worry?

 

hmmm some new info. i found out whats causeing the crash. if i am connected to the internet (via my dialup connection) and F@H is running thin it would crash if F@H is not running thin i get no crash. but if i am not connected to the internet and F@H is running i get no crash. What gives???
