Well I am stumped at this point except to wait for you to post back with the results of the SFC Scan after inserting the OS CD first.
I now think you may have a virus to tell you the truth, but cannot see how you can post a HJT log here from said computer without internet connectivity to it.
How long is it since you cleaned out the temporary internet files and other maintenance on the computer that is giving trouble? All the suggestions below can be done without internet connection.
Now I would suggest you open "control panel" and then "Internet options." With the 'internet options' open, you will see the general tab. Next click on the "content" tab. You will see "clear SSL state." This normally is performed automatically but I have come across old data left in here. While you are here, you should clean the "auto complete" as well. There is a lot of data stored here that can breach your security and privacy. It is best to uncheck all three boxes and never use this feature, however if you like this feature, keep it.
To just clean the stored data, enable "auto complete" button and then the "clean passwords" then OK. Then enable the "clear forms" and then OK. It will wipe all of the stored information.
Now let's move on to the Java files. Open "control panel >settings and find "java plug-in" and click
on temporary internet files >settings >delete files >enable Applications and Applets, and Trace and Log file > okay.
Now while we have it opened, let's adjust the size from 'unlimited' down to "maximum 4 MB" and you
will be ready to go.
Another item that seems to get overlooked on today's maintenance routine is the "C:\windows\temp" folder. You should delete everything that is in this folder, BUT not the folder itself. If you have never done this, it will have a ton of stuff in it.
So run your disk cleanup, defrag, delete cookies etc often. There are other variations of these utilities
available although I have yet to find a problem with the ones that Windows provides.
To flush DNS cache click start, run, type cmd, and type ipconfig /flushdns and press enter. (Note the space between the g /)
DNS = Domain Name Server, the cache referred to is where Windows stores all IP addresses it collects as you surf typing the IP to the domain name to surf to, this cache can grow large over a period of time causing a slowdown on your computer surfing and interaction.
Please reboot and see if the above helps
kind regards,
PS. Just received your last post re SFC Scan…thought that may have helped, but alas no!
