I was trying to fix a power problem with my video card and possibly my burner, so I was looking for the voltage on my power supply when i came across a little red switch and a sticker saying 115/230v so being stupid as i am, with the computer on i switched it from the current 115 to the 230. When i look back at my screen it was blank, so my first thought was that i had moved the monitor cable which has given me problems before, so i tried everything i could think of including turning on and off the computer and monitor in every kind of combination. I took out the little round battery on the motherboard, and I disconnected everything except for power cable and monitor cable. Still i havnt gotten anything so far and the monitor seems to still work because i connected it to my sisters laptop (the one im using now), and my computer seems to turn on with no problems
