Default browser opens the home page very often from the sudden...

Hi,

on my Notebook the default browser (either IE or Firefox, it need to be the default browser) opens a lots of Windows after some time and that more often during one Windows session and if using the Explorer and I get to this time, then it turns to my home page (here then using Internet Explorer I think) - this is also if opening control panel... if that happens I can barly to something... if I have no default browser active, the problem with Explorer.exe turning to the home page is still..

Well... my big problem is that I now have 3 times completely re-installed Windows XP with SP2 embedded and without even installing anything (I am not sure if I had Windows activated always but I think so), I always have this problem again...

And I don't know what the problem is...

As additional information Microsoft Antispyware (up-to-date) says no spyware threats found and the HiJackThis-Log just says this:

This SmartLinkService seems to be there because of the Modem Driver (which was already installed after Windows installation, not installed by me manually)... and the slserv.exe is there in C:\Windows\System32

which should be normal...
Microsoft Antispyware was not installed before, now just to find out if there is any Spyware installed...

 

I have now also tested a Windows XP Installation without any SP embedded, same problem (completely clean installation), this time not even activated...

 

ok... I think I now know what the problem is, there is some problem with the keys for web, e-mail a.s.o., they don't work always (normally I don't use them) and so I now tried SharpKeys to look for which keys get pressed, well they don't always get pressed if I press them... but asap my problem comes up, there stand Web: Home (E0_32) so the problem seems to be a bit hardware based... or BIOS-based... well I think I will disable those buttons somehow.. I think per TweakUI or SharpKeys this is possible if I am right...

and I just had the notebook in repair and the mainboard was exchanged... and a new BIOS version was put on it... maybe this is the problem...
