I've been recently facing a lot of problems with my laptop but now I am at rock bottom. I left my laptop alone for about 10 minutes and I came back my screen was black. I moved the mouse but to no avail. I then restarted it thinking it would reboot fresh but after the TOSHIBA logo the computer went into a black screen again. I do know I had a virus and I was having trouble with sound on my computer (a problem associated with the driver) is the black screen rooted from the above 2 problems? What do I possibly do now?
