My Vista Ultimate notebook has been running at 100% CPU for a few days and even with the use of sysinternals tools I have been unable to see what the cause of the problem was. I removed a few pieces of recently installed software but it made no difference. Safe mode was fine.
I stopped AVG 8.5 and (even though it was not scanning) the CPU dropped to 8%.
I decided to remove it before considering resinstalling it (or trying Kaspersky). and noticed that whist uninstalling it had some version 7.x elements.
Maybe conflicting modules?
