Help please! My toshiba touchscreen has been broken for a long time now, we've just used an hdmi cord to connect it to a TV and used it as the monitor. Well it started acting up, getting slow and freezing so my husband was going to delete and reinstall the network drivers, (he says thats all) but we lost connection to our wifi before they could reinstall. We got busy and forgot about it for a little while and when we came back to it it wouldn't show anything on the TV anymore. I've tried using a new hdmi cord, tried using a vga cord, but i got nothing and I dont know how to fix it without being able to see and navigate the laptop. Is there a way to force windows to reinstall or update the drivers without being able to see the screen? Can somebody help me please?
