ok a friend of mine asked me if i could take a look at her pc. She said that the sound won't play and that she can no longer connect to the Internet.Upon starting the system the 1st thing i determined was that the problem maybe virus related since i found no virus protection on the pc at all.So i downloaded the free avg 8.0 but when i tried to install it its said that i need to install win xp sp2 so i did.I had found that the internet problem was resolved when i used the usb connection as when i did a check it said that the Ethernet card wasn't working and as for the sound it said no audio components were found. Ok after i installed sp2 the resolution went from an already bad 16bit to a horrid 4bits almost unsee able no matter what i tried i couldn't change the resolution so i tried to go in safe mode to see if i could adjust then but when i attempted to the pc rebooted and now i'm at my current problem the machine boots but the monitor will not come on it stays in the standby state and i get no picture the keyboard lights up as to show the pc is still working i even typed in her password at the startup screen and can hear activity but the monitor will not come on i turn it off and back on again and it will stay green for a couple of seconds then i will here a click and its back to the standby state again. I don't know to do can someone plz help i'm at my wits end
