Hi, lately, my desktop (Lenovo Ideacentre) has been crashing, generally when watching YouTube, with the message kernal dump mode something or other. It reboots fine, then will work OK for a bit. After crashing, I can only enter the password with the on screen keyboard, not with the mouse and keyboard. I've googled the issue-it all seems a bit beyond my computing skills! Anybody got a fix that an idiot would understand?
