|Again, purely for elimination there are a couple of things we should do:|
Download, install, update and run MalwareBytes freebie (green icon top right):
Unless it finds anything of consequence on the quick scan I think we can assume your issue is not virus related.
Run Windows 7 disk check:
This is against the off chance that there is a bad patch on the HD that needs fixing. It could be a part not used when in Safe Mode.
We are a bit stuck with throwing things at this issue in the hope we can unearth something. Some folk have resorted to reloading Windows but I doubt either of us want to think in that direction. In another case a RAM check for many hours found a faulty stick of RAM. If you have more than one you could try running the system with just one at a time but I'm inclined to agree that if it is OK in Safe Mode it points generally to software. Whatever, if you do decide to peer inside then clean the RAM edge connectors with a pencil eraser as oxide can cause intermittent faults. I usually pop the sticks in and out a few times to clear any oxide off the sockets themselves too.
As far as bigger guns are concerned there is always this:
It relies on what system disks you have available or whether you would really want to go this way - later if necessary maybe.
Always pop back and let us know the outcome - thanks
