ok, so i was just starting up a game on my computer when my screen just went black and my computer just shut off. i turned it back on but there was no output and it wouldnt turn off. so, i unplugged it and plugged it back in. But this is where it gets bad, it wont turn on again, at all. I know it isnt a power strip issue because i have other things plugged into the strip tha are still working. I built the tower in november and have had no problems since, i have played the game that i started many times before. the only thing i can think of is that earlier today i blew the dust out of my computer but i have done that before. if anyone nows what could be going on please help. im 15 and i have been saving up for ths computer for a long time, i just want to know whats happening.
