Hello Trish, from the research I've carried out the intel update may have caused the problem even though you don't have dual core.

Are you still unable to do a system restore? As this would be the safest way to fix the problem.

Try going in to safe mode and do a system restore, I would like you to try the re-boot to see if the problem still occurs.

If any of the above fail to solve the problem, back up any important files as a precautionary measure and then I would like you to navigate to the intelppm entry in the registry that we've already discussed and change the start value to '4'.
This should disable the driver that I think is causing your problem.

The main issue with this driver is to do with servers, and after seeing one of your errors relating to a server I would hope this will fix your PC.

Let me know how you get on.

Regards

Martin
