Yesterday my keyboard and mouse started acting weird. The keyboard isnt typing the correct letters (for example, the A key doesnt work at all, the Z key is functioning as the delete key, the backspace key types a random string of letters, and the shift key tabs). The mouse isnt functioning properly either (the left click is highlighting whatever I click on, and if I double click it opens the properties menu). Ive never had a problem with either before - the mouse is an old Dell mouse, and the keyboard is a Dynex which is only a few months old. The PC itself is custom built, running Windows XP Pro x64 OS.
I tried restarting the computer however I cannot type my login password to get back into the computer (Im writing this post from an old laptop). I attempted logging in to safe mode however the up and down arrow keys on the keyboard arent functioning so I cannot scroll down to choose the safe mode option, and the enter key doesnt seem to be doing anything either. My account is the only account on the computer, and is a passworded administrator account, and there is no guest account so there is no way for me to access the computer without being able to type my password.
I dont believe that this is an issue with the hardware as the mouse works with my laptop and Ive never had an issue with either piece before. Im concerned that it might be a virus messing with the controls. Before I restarted my computer I ran adaware and spybot which found a few things which I removed, but still didnt solve the problem. I attempted to run avg antivirus, however the program wouldnt update and hitting the Scan Now button wasnt doing anything.
I really need to be able to use my computer, but I cant get past the login screen to do anything at all. I have no idea how to proceed from here.
