Hey guys, first time poster here. So I guess my dad was trying to install an external DVD burner, and when he plugged it in and put the driver CD in, the computer froze, and after restarting now nothing will come up on the monitor. The computer will turn on, but the light on the monitor remained orange as if no signal was coming in. After waiting a day, the computer would turn on with the keyboard plugged in, but it was not responsive to the ps2 keyboard when it was on the desktop, couldn't bring up the task manager or anything with ctrl alt delete, and then when you plug in the usb mouse, it freezes again, and goes back to the no display.I'm thinkin maybe a USB problem or something? The external burner is USB also. Can't get it to go into safe mode, I don't think it's taking input from the keyboard at all. The lights on the motherboard and case turn on with the power, but that's it. PC with XP with SP2 I believe, a pentium 4 fairly new computer, maybe 3 years old or so. Does anyone have any ideas about this?
