So, today as I was trying to get onto my computer, it just wouldn't boot up (it was running just fine 4 or so hours beforehand). I've done a bit of reading, and am still unsure what the problem could be. It acts normally up until after the initial start up. Then it just sits there, black screen and nothing more (not a moniter problem, I've alread confirmed that).
I haven't messed with the thing since I discovered it wasn't working this afternoon, seeing how I leave to go on vacation in like...an hour or so. Has anyone here dealt with this problem before or at least know what I should check out after I get home in 13 days? Any help would be most appreciated.
Fake edit: Also apparently a friend of mine said it might be my motherboard, which frightens me.
