In addition to this I have re-installed my Zone Alarms firewall/spyware & virus software.
Now following this whenever I use the IE browser (6.0) the PC reboots. Strangely this is not immediately and will allow a short time of web access, it also has no affect on the use of Outlook Express.
Incidentally Mozilla Firefox seems to also be affected, so my only guesses are perhaps a conflict issue has arisen or the over-installation (rather than clean install with a re-format) of the operating system has produced this bug!
Does anyone have any suggestions how I can go about restoring my internet access?
BTW I have up to date virus definitions and a scan reveals nothing untoward.
