I have a Dell desktop computer that is several years old. I started having issues with internet searches being redirected. I found that somewhere along the line, a bunch of malware programs got installed on the PC such as yontoo, wambah(?) and others. I thought I had deleted all the files and add-ons but especially with yontoo, I kept finding files that the search feature did not find even though they were named "yontoo". Long story short, I tried to reboot in safe mode with F8 but it did not work. So I read that I could change the boot up instructions through msconfig and I reset the startup to boot safe mode (minimal). Now when I try to boot the machine, the motor comes on but nothing happens. Black screen with no cursor. Doesn't appear to doing anything but running the motor. I created a recovery disk from another computer and tried booting that way, but no go. I'm running Windows 7. Anyone have any idea where I go from here?
