I brought my computer home from college, where it was functioning fine, and after I plugged it in at home it loaded up once, and then froze and now it won't reboot at all...it comes up to a black screen that says reboot error....this same thing happened last summer when I plugged my computer in at home...it is not hooked up to a modem or the internet in any way now that I'm here, what could be causing this?? more importantly, how can I fix it??
