Ran AVG, system was clean.
Ran Malwarebytes, system was clean.
The system is working properly in safemode and doesn't seem to have any software problems that I can find, I think this may be a hardware issue but I do not know how to diagnose it.
Someone else has worked on this computer and has system restored it, to no effect.
When you try to boot the computer it will only boot in safe mode (including hitting F8 and manually selecting Boot Normally). If anyone would give me a starting point I would appreciate it. I will look on the forums for similar issues and other possible solutions. Thanks in advance.
Edit: The version of Vista is Home Basic with Service Pack 2
