This sounds like either a virus or ad-ware. Try this first. Download these they are free programs.

Anti spy and anti virus.

Ad ware also free.

this is a registry cleaner when installing don't install toolbar.

Once all are loaded don't run yet restart in safe mode ( tap F8 on Reboot) you will get a warning box, click ok run all the above mentioned programs. (get coffee this could be awhile)

do disk clean up with all boxes checked, next do defrag (all still in safe mode) after defrag is complete reboot normally.

This should eliminate problem. If not come back %26amp; we'll try something else.

Hope it helps

Get SP2 from a website like download.com. As for systemupdate. It sounds like your windows is corrupt. simply boot from CD and repair it.
