Hi. My Toshiba laptop has been randomly crashing/freezing with colorful static on the monitor and loud static noise from the speakers (usually if I'm on youtube). This has been happening on and off for months. Sometimes it just crashes to a black screen and restarts but often it does the dramatic crashing. I don't have a good connection to go downloading troubleshooting stuff and I have no idea if its the battery, the video card, a virus (because rarely on boot-up the microsoft security essentials is turned off or malwarebytes has an error about root-kits that doesn't come up again when its restarted), or what. I don't know what to google to even start finding answers to this problem and I need help.
