have a dimension l933r its a old one got it from a friend . tag # dt5pk01 i put a new hard drive in it with xp nt format It was working great.Until i had a problem with firewall sotfware. it froz up. At the end it said that windows shut down my system

to save data. I did not care about data. But now the pc will not even boot up. There

is no lights on back the power is working fans come on a drive,cd, even re-formated hard drive again so there is nit even a op system on it . the hard drive starts up

but the bios will not boot Nothing on the screen. Can not find anything on dell website on mother comands to get bios to restart or system to boot. A boot

disk in a drive will not work. or cd. I unpluged all hardware, cards ,drives and rebooted still nothing The light on the mother bourd gose on when i turn it on

there is power to it .I do not think the key bourd doing anything. Hope someone can help. Thank you Eric
