I have a Vista workstation that when I try to boot to Safe Mode, it reboots just when files are just about loaded. It will boot to production mode but I cannot get to the internet. When I try to run diagnostics it says to open Service Control Manager. Services opens, but not sure what to look for. I connected hard drive to another computer (as a slave drive) and ran Malwarebytes. It found only low risk issues. Any ideas what is causing these issues?
