I am using a Gateway laptop which came with Windows 7. Over the past few months I have been having a problem with +, 9, and / signs appearing where ever a textbox is available. I cannot make the signs stop, when I delete them they are immediately replaced. Alternatively, when I start up my laptop it is accompanied by a loud beeping noise which will not stop unless I'm in certain screens, I assume screens where the keyboard is disabled.
Though I had issue with the laptop, I managed to install Ubuntu, a dual boot, essentially and though I will get random signs appearing on this OS, I can stop them. Once I stop them, they do not return.
Recently I wiped my laptop, losing Ubuntu and reinstalled Windows 7, but the problem remained, making my laptop completely inaccessible until I reinstalled Ubuntu.
When I wiped it, there was always at least one partition which I could not format and one was always automatically created.
Does this sound like a Virus or a Hard Drive issue to you? what steps can be taken to solve the issue?
I uninstalled the keyboard, am using a usb one as the one that came with my laptop ceased to function, and I went for a month or so without a firewall.
