When I start my laptop after the Press F2 to enter Setup screen it beeps without showing anything. After shutting it and restarting 3-4 times Windows starts and displays ++++++++++++ in all text boxes. I scanned with anti-virus but nothing was found. What could be the cause?
I'd lightly tap all the keys, and, especially the "+/=" key, just to make sure no keys are stuck...
Can you actually enter the setup normally, and manipulate the menus, examine/make changes to date, boot device priority, etc..?
Once the system boots it works normally. But whenever a text box appears it diplays ++++++++++++++++ in it. I then have to delete it and start typing.
Was the laptop's OS drive encrypted?
I never did any such thing.
How did you scan with an AV? (Are you saying you can boot to Windows desktop and operate normally?)
