I was running my PC for about 2 hours and everything was running fine, then I turned it off and when I tried to turn it back on, the LEDs came on for about half a second then everything turned off and the power button and no affect after that. If I remove my video card, everything boots up and stay running but I do not have an image on my monitor. Does that mean my video card is broken, or does that mean my PSU doesn't have enough wattage to run everything? I know my video card says it needs a 500 watt PSU but I read that it works on PSUs under that.
