I attempted a BIOS update earlier today. After it finished, it said that the screen may be black and LED's may blink for a while after (I don't remember the exact wording). Well, the screen was still black after about 4 hours, so I turned it off, and now it refuses to boot. There are no beeps, no error codes, no POST, nothing, so I figure the BIOS must be corrupted or something. I've tried resets and the windows key+b trick with no luck. I've spent a few hours trying to figure out how to run a the BIOS from a USB, but info is a bit scarce, so I couldn't figure it out. So, what else can I try? I don't really have the time nor the money to send it in for repairs, but I need this computer for school by next week.
