can anyone help me with this? i recently changed my background picture and i noticed this blue tint to everything on the desktop and to a certain extent on Firefox and Internet Explorer.So i changed it again and still the same thing .I don't know what caused it but its a minor annoyance that i would like to correct soon. any help?

hey everyone i have an old HP computer that will not turn on. i believe what casued it was my brothers defective Ipod. he plugged it into my usb charger and nothing happend charging wise and my itunes never opened. i did get a messege from the tray saying there was a power surge or something and shortly after my computer shut off and i could not turn it back on. When i tried to turn it on the light would come on and i got a beeping noise from the case speaker.i think it might be the power supply but im not sure. any help would be appreciated.
