turning on my Gateway computer, I can get the logon screen for windows 7, I put my password in and then I see the desktop screen for a second then the screen goes white. I CAN press control/alt/delete and get the task manager option. If I choose any of the options I get nothing but the white screen. Windows IS running behind the white screen but I can not see anything but white. Is my monitor dying or is it the computer?
It's not, it's a stupid piece of malware. You can boot in safe mode with command prompt and then when you get a command prompt just type explorer and then you can go about running your anti-malware tools like Malware Bytes etc.
