connect via usb modem ok /router not ok

[muzzler]

Hi people,
I'm trying to get this linksys wag54g router to work on my friends pc and it's driving me mad!!
The thing is i don't think it's the router at fault, but something on her pc. here's the situation:
usual connection : tiscali 2mb usb modem- dials up no problem and internet explorer works.
go through the routine of setting up the router- no access at all, not even to the router.(checked lan cable etc- all ok)
Boot into safe mode and no problems at all- router is set up and will connect and internet explorer loads up.
Boot back into ordinary windows and nothing again. (router still on and connected)
if i go to tools/ check internet connection (in ie6 i think it is) it says that http,https and ftp are not available- check your firewall.
I've tried disabling the firewall, restoring defaults and even disabling the router firewall- it still wont work!
Sorry for the long post but if anyone can help it would be much appreciated- i have clumps of hair torn out of me scalp!
regards,
Steve.

hi ,
thanks for the quick replies,
yes, the settings are on auto (for ip address, dns etc) and i even tried making a new connection just to see! but, alas, no joy!
ive also deleted all her network connections (usb dial up) and still no luck
she says certain things like her kid's java games wont download aswell as it wont let her.
it's windows xp btw.
I've suggested a clean install of her system as it's so full of junk and is very slow.

cheers chaps, your help is much appreciated.
i'll try the suggested software and if no joy will attempt a re- install.
(i bet any money she can't find her xp cd or repair cd!! lol)
it never stops!
regards,
Steve.
