If this problem started after upgrading the memory, remove the new memory and replace with the original memory chips. If the problems go away, the new memory is either bad or incorrect type for your model. Crucial.com can give you reliable info on the correct memory. You should also run the extended hard drive diagnostics which are separate from the system diagnostics. Have you tried booting to your vista dvd? Since you are able to boot to Safe Mode, there might be something--driver or program--that is loading that is causing the problem. Check your Hardware Device Manager for driver problems. With Vista you should not be using any utilities like Defraggler and CCCleaner. Uninstall them and any other utilities in Safe Mode. Disable Zone Alarm temporarily since that is also known to cause problems with Vista. Do one thing at a time so you can find the culprit.
