We have a Dell desktop running Windows XP which is about 8 years old. We only use it for surfing the net and storing some pictures. Last night after about :45 minutes a blue screen popped up stating a new hardware error. I failed to write it down so I'm not sure exactly what it said. I proceeded to shut it down and then when I tried to restart the system there was a beeping sound and the fan speed increased to what appeared to be the maximum speed. I shut it down and tried several times and nothing changed. So now I have nothing showing on my monitor and I have tried everything I can think of which is not much. I have a lack of knowledge on this topic and would appreciate any help you can provide. Thank You!!!
