I scoured the internet looking for a solution to this behaviour: Can not start windows 7 without running memory diagnostics first. The computer would continually restart during the windows boot process.
For all those people who have this issue. Here is the solution!
1)I identified the cause as a root kit in the boot record (I ran hit man pro and it identified it and removed it.
2)I did have to press f8 during each boot and choose repair my computer and run the windows memory diagnostic for few seconds then hit ESC. This was the only was to bypass the root kit and start windows. This enabled me to run hit man pro.
2)Once hitman pro had successfully ran and rebooted (i had to do step 2 above to ensure a successful boot). The computer was working fine.
